Best Water Flosser

In this post I run through my recommendations for the best water flosser, or oral irrigator as they are also known.

The recommendations are based on my own hands-on testing, completed as part of my water flosser reviews. 

My number 1 choice is the Waterpik WP-660, which I found to be excellent when testing. 

The Waterpik Cordless Advanced is the best cordless water flosser, based on cleaning performance. But I personally use the Sonicare Airfloss Ultra because it is not as bulky and it’s easy to use. 

However, I have rated the WP-660 as the best overall because Waterpik models have performed better than the Airfloss in clinical trials. 

But that’s not to say you should choose between those two electric flossers alone. All of the products below are excellent choices. 

The most important thing is that you floss regularly, so whichever tool makes that easiest to achieve is the best choice. 

Immediately below you can find a list of my recommendations, and further down the page, I’ve included a detailed buyer’s guide, which was medically reviewed by our in-house dentist Dr. Gemma Wheeler.

A quick note on terminology

There are various terms that are used interchangeably to refer to these devices, including:

  • water flosser
  • electric flosser
  • water jet flosser
  • oral irrigator
  • water toothpick

The name of one of the best known brands, Waterpik, is also used by some to refer more broadly to these products. 

But from a technical standpoint, they are all one and the same. 

Our top 8 picks for the best water flosser you can buy in 2021

In the sections below you can read a little more about each water flosser that we have included on the list and why.

1. Waterpik WP-660

Short review: It is the standard to beat.  

It offers all the desirable features including:

  • A 90 second run time
  • Built-in timer/pacer
  • Water control button on the handle
  • 10 pressure settings
  • 7 tips included in the box
  • A slimmer profile

It is too now quieter than other models too.

Available in a range of colours this oral irrigator is backed by many clinical studies.

Best Water Flosser 2021 1

What I like

  • Excellent cleaning offered
  • Good box contents
  • Various pressure settings
  • Large water tank given the units size
  • Water control button on handle

What I dislike

  • The massage mode seems a little unnecessary
  • Not the largest tank given it’s one of the more premium models
  • It is quite expensive

Buy from Amazon.com.

2. Waterpik WP-560 Cordless Advanced

Short review: The best true cordless water flosser.

A good size water tank, with variable pressure settings built into a smart and appealing unit.

The box contents is good. It is by far the cheapest, but it is made by a leading brand and is clinically proven.

With a built-in rechargeable battery complete with magnetic charger it is convenient to use, although the battery life could be better.

What I like

  • Cordless
  • Cleaning ability
  • Rechargeable
  • Box contents

What I dislike

  • Size
  • Price

Buy from Amazon.com.

3. Sonicare Airfloss Ultra

Short review: Perhaps not strictly a water flosser, the AirFloss uses a combination of water and air to achieve a similar effect but delivers short sharp bursts to get in between the teeth.

What makes it so good and desirable is the much smaller profile, it’s cordless, really easy to use and can achieve a clean in 30 seconds. It makes for effortless everyday use.

The Ultra model offers 3 different burst configurations so you can select the mode that is right for you.

The unit comes in 3 different colour options.

Whilst the AirFloss is actually our preferred go to flosser, clinical studies show Waterpik models are better.

Best Water Flosser 2021 2

What I like

  • Simplicity of use
  • Less messy and takes less getting used to
  • Different burst modes
  • Design
  • Portability
  • Battery life

What I dislike

  • Targets only in between teeth rather than along the whole gumline
  • Price

Buy from Farmers.

4.Waterpik Ultra Plus

Short review: Very similar to the Waterpik WP-660 that tops this list, the Ultra Plus isn’t quite as feature rich. It is a fraction cheaper, but there isn’t much in it.

It comes with a good box contents, which includes 7 tips.

The lid of the unit doubles up as a storage compartment for those tips.

A full tank of water will last around 90+ seconds of use.

There is a choice of 10 pressure settings, controlled via a rotating dial on the main unit.

Water flow can be switched on and off from the handle and all tips can be rotated a full 360 degrees.

What I like

  • Excellent cleaning offered
  • Good box contents
  • Various pressure settings
  • Large water tank
  • Nozzle storage lid

What I dislike

  • It is quite expensive

Buy from Shaver Shop and Chemist Warehouse.

5. Waterpik Cordless Select

Short review: Another cordless option from the reputable brand that is Waterpik.

The water tank offers up to 45 seconds of usage depending on which of the 2 pressure settings you select.

Designed to be quiet when in use, it is also easy to recharge thanks to the magnetic USB charging cable. It charges in just 4 hours.

4 water flossing tips are provided and they all rotate a full 360 degrees.

It is too waterproof for those who like to use a water flosser whilst in the shower.

Best Water Flosser 2021 3

What I like

  • Cordless
  • Cleaning ability
  • Rechargeable
  • Box contents

What I dislike

  • Price
  • No travel pouch included

Buy from Shaver Shop and Chemist Warehouse.

6. Fairywill 5020E Cordless Water Flosser

Short review: Fairywill are all about value for money and there is absolutely no denying that this is what you get with the 5020E.

It does not look the absolute smartest, nor does it feel the most premium to the touch. But, to a large extent when you consider that this is at least half the price of most other cordless options it is a sacrifice worth making.

Available in different colour options, an amazing 8 jet tips are included in the box.

You do too get 3 different flossing modes from this cordless option.

Although the battery will last about 30 days on a full charge, the detachable USB style cable is not quite as slick as the magnetic options you get on Waterpik models. It is too quite easy to lose the little rubber grommet that fits inside the charging port of the unit.

What I like

  • Price
  • Box contents
  • 3 flossing modes
  • Colour options

What I dislike

  • Charging cable
  • Material quality

Buy from Amazon.com.

7. H2ofloss Water HF-9 Flosser

Short review: A budget countertop water flosser.

You can’t really argue with what you get in the box for the money.

The water tank has an impressive 800ml capacity.  12 tips are included in the box and there is a storage unit for these provided.

The nozzles can be rotated a full 360 degrees like premium brand Waterpik.

Adjust the pressure from 5-110PSI via the button on the handle and you can get a minimum of 150 seconds running time, which is pretty is impressive too.

Quality is not the best and there are reports of some units failing early in the life of the product.

If you want to try a countertop option and can’t commit to spending a lot, this is an attractive option.

Best Water Flosser 2021 4

What I like

  • 12 tips included
  • Tip storage unit
  • Large 800ml water reservoir
  • Long running time
  • Variable pressure settings
  • Price

What I dislike

  • Quality and reliability concerns

Buy from Amazon.com.

8. Oral-B Aquacare 4

Short review: The Aquacare 4 just about does the job.

It is not the best example of a cordless water flosser.

I have used equivalent products from lesser-known brands that have delivered a better overall experience.

The build quality is questionable.

The design and button placement isn’t ideal.

The power of the water jet isn’t the most intense and the number of advertised modes is a bit misleading.

I expected better from a brand leader like Oral-B.

What I like

  • Cordless
  • Rechargeable
  • Different water streams

What I dislike

  • Build quality
  • Nozzle design and rotation
  • Button placement
  • Chunky charging stand

Buy from Shaver Shop, Farmers, Braun.net and JB Hi-Fi.

Water Flosser Buyer’s Guide

Mention flossing and most shudder at the thought.  It is awkward, a hassle, it hurts and recent news articles suggest it might not be as effective as we once thought!

Brushing your teeth only cleans 60% of the tooth surface, some 40% goes uncleaned unless you partake in interdental cleaning whether that is flossing or using interdental brushes.

If flossing or interdental brushes are not for you, there are alternatives! One such solution, backed by clinical evidence, is the use of an electric water flosser.

Read on to get extensive information on electric flossers and understand why I have picked the devices recommended below.

What is an electric water flosser?

An electric water flosser, or an electric flosser / water flosser as they are also known, is an oral hygiene product that pushes water (or mouthwash) into the mouth at pressure through a nozzle, with the intention of washing away plaque, bacteria and food debris that might reside on the teeth and along the gumline.

It is an additional or alternative to the more conventional flossing you may be familiar with.

Kind of like a jet wash or pressure washer (albeit smaller and less powerful) the water is a soft, yet effective option for achieving a cleaner and healthier mouth.

A water flosser in reality is taking advantage of modern technology to help you achieve good oral health with an emphasis on convenience and comfort.

Best Water Flosser 2021 5

What’s the difference between a water flosser and oral irrigator?

Nothing aside from the name.

These are two terms often used interchangeably, but they describe the same sort of device.

You may also see them referenced as water irrigator or a water jet flosser.

How does a water flosser work?

The flosser has 2 major parts, the water tank/reservoir and the pump.

The tank is normally visible and easily accessible whilst the pump is situated inside the body of the flosser unit.

Powered by electricity (be that mains power or power stored in a battery) when the power is switched on, the pump draws water from the tank/reservoir through pipes and tubes, pulled into and out of the pump and up through the the tip of it through a nozzle at the end of the flosser at a higher pressure to deliver a stream of water into the user’s mouth.

Subject to the model of water flosser, this stream of water can be switched on and off, delivered at higher and lower pressures and oriented at different angles to be more effective.

For the best effect, it is advised to fill the tank with lukewarm water, although cold is fine.

Also acceptable is a splash of mouthwash in with the water for added freshness and potential health benefit.

Types of water flosser

Electric flossers can come in various shapes, sizes and designs.  Whilst they aim to do the same job there are either designed to be countertop mounted or portable.  In other words one needs mains power all the time whilst the other is cordless.

  • Corded (countertop)

Typically the more feature rich oral irrigators must be sat on a countertop or work surface because they are larger and less portable and require mains power to function.

A larger water reservoir for multiple or longer one time use, extra power settings and accessories are common features of this type of flosser.

Corded water flossers tend to be the most capable and effective.

To give you an idea of size, they typically take up a surface area similar to a kettle would in a kitchen.

Best Water Flosser 2021 7
  • Cordless (portable)

Powered by batteries, this type of flosser is smaller for one handed use and is not tied to mains electricity via a power cable.

Ideal for those who do not have a power socket in the bathroom, a portable flosser has the water tank built into the handle, which means less usage time and tend to have less control on the power of the water flow.

Why do electric flossers exist and do I need one?

Oral health is a massive issue globally.  Even in the most developed countries too few are taking good enough care of their mouth and teeth.

In 2010 a study by the Centre for Disease Control and  Prevention (CDC) found that 47.2 of Americans over 30 years old had some form of gum disease.  That is 64.7 million people in the USA alone.

Gum or periodontal disease (as it is otherwise known) is a chronic inflammatory disease that affects the gum tissue and bone supporting the teeth. If left untreated, periodontal disease can lead to tooth loss.

Want the cold hard facts? Check out this infographic, you will no doubt understand the importance of some kind of flossing regime having read it!

Typical signs of periodontal disease are red or swollen gums, tender or bleeding gums.

Sadly this is an all too common situation and the reason the gums and teeth get like this is though a poor oral healthcare routine.

Best Water Flosser 2021 9

Flossing is often associated with bleeding and pain, but actually its normally due to a lack of proper care that blood and pain present themselves most often when flossing.

Gum disease is reversible however, if caught early enough.

This is where the water jet flosser then comes in.

It has been developed to be a more comfortable, enjoyable and effective way to clean in between the teeth and along the gumline.

The pulsating action of a dental oral irrigator creates a small-scale compression and decompression effect that forces disease-causing subgingival bacteria out from deep within gum pockets (the spaces created around teeth when gum tissue and bone are destroyed), where ordinary floss can’t reach.

You do not have to have or use an electric flosser.

Many people have chosen to because of the benefits (shown below) that these devices bring.

Best Water Flosser 2021 10

Unlike floss there has been more thorough research into the use of water flossers with Barnes 2005 study (1 & 2) being the overarching evidence users want.  His study found that the addition of a water flosser to a daily oral healthcare routine resulted in a 93% reduction in bleeding and up to 52% better at reducing gingivitis (inflamed gums) than traditional dental floss.

Pros and cons of water flossers

Like most things in life there are pros and cons to using a water jet flosser.

Not everyone will agree with the benefits and drawbacks and not all points raised will apply to all users.

Oral irrigator manufacturers primarily ‘sell’ them on the convenience and comfort of using one in comparison to regular dental floss which is something many of us are drawn to.  But in this instance there is clinical evidence to support the sale.

Here is what I believe to be the main benefits and negatives when it comes to living with and using an electric flosser.

Benefits of an electric flosser

  • Ease of use
    • Very simple to use and more enjoyable to use than regular string dental floss and interdental brushes. No awkward hand trickery required to get to all the gaps in your teeth and mouth.
  • Comfort
    • The often offer adjustable pressure and angled tips, which typically means a much more comfortable experience to use with a lot less pain.  Bleeding is much less common  It is a more gentle approach and works well for those with sensitive gums.
  • Speed
    • Once perfected in the technique it is often quicker than regular flossing.
  • Enhanced clean
    • The jets of water gets into even the smallest gaps and can even flush out food particles bacteria under the gumline which traditional flossing cannot reach.
  • One product that does the job of many
    • You might currently have string dental floss and interdental brushes.  Potentially a water flosser could replace these.
  • Braces
    • Exceptionally good for those with braces as the water is more effective and easier to use than traditional flossing techniques.
  • Dexterity
    • If you have limited dexterity a flosser can really help make the process of interdental cleaning easier due to the design and electronic assistance. May be more suitable if you have limited hand movement, e.g arthritis.

Negatives of an electric flosser

  • Cost
    • Considerably more expensive than a packet of string dental floss and a lot less portable. Consideration needs to be made for the ‘lifetime’ value as over time their cost is significantly reduced when you compare to buying a reel of floss at a few dollars ($) each time.
  • Size/Portability
    • Whilst smaller cordless options exist the counter top flossers are reasonably large and when space is limited can feel like an unnecessary item or a waste of valuable shelf space.  Even the portable options are larger than might be ideal for a weekend travel bag for example.
  • Power
    • They require mains power and this can limit where they are positioned and will not work for all.  For those with no mains power in a bathroom the cordless options exist.
  • Technique
    • It does initially take a little getting used to and can be messy until you perfect the method.
  • Effectiveness
    • Plaque sticks to the tooth and floss scrapes this away, some suggest traditional dental floss is better for removing plaque than an electric water flosser.
Best Water Flosser 2021 11


Whilst a variety of brands exist within the water flosser market, it is predominantly dominated by a company called Waterpik.

A US brand, the company has the most extensive range of products to suit different users needs and budgets and really sets the standard.

In fact many will suggest buying a Waterpik — Waterpik is a brand and not a product type.

Due to their dominance, Waterpik have become synonymous with this product much like Hoover have with vacuum cleaners.

Oral-B, Sonicare, Panasonic are other big names that exist in this space amongst others.

What do the facts and clinical studies say

The results of clinical studies and what advice you get from dental professionals often depends on a number of circumstances.

Many major dental brands have financed clinical studies.  Whilst the results have to an extent be justified and fair, there is inevitably some influence over the reported results if their own product is being tested.

Brands ideally want compelling statistics to help sell their products, thus focusing on the positive results is important; often being creative in the way statistics are reported to allow quotes such as X%, but perhaps not making clear how big the trial was etc.

However, in the water flossing market, market leader Waterpik has set a standard, not only conducting its own studies but opening up to independent bodies and industry professionals to test and challenge the products to really show whether it does or does not work.

Best Water Flosser 2021 12

The result is an overwhelming support for their products and an industry wide acceptance that a Waterpik Water Flosser is a viable product for interdental cleaning.

A 2005 study by Barnes of 105 participants found that the addition of a water flosser to their routine resulted in a 93% improvement in reducing bleeding and up to 52% better at reducing gingivitis than traditional dental floss

A 2009 study by Gorur at the University of Southern California Centre for Biofilms found that a three second water flossing application removed 99.9% of plaque biofilm.

Dr. David Jolkovsky, a diplomate of the American Board of Periodontology, wrote a literature review that addressed the safety of the water flosser.

The studies unequivocally showed that a Waterpik Water Flosser reduces inflammation, removes bacteria from deep periodontal pockets, does not cause damage to mouth tissues and is in the same range as brushing teeth, flossing, and using wooden sticks in the incidence of bacteremia.

Strong praise for these products, whilst the evidence is present to show the benefits there will always be those who still advise on a traditional string floss or interdental brushes.  There are still valid arguments for its use.  Most notable is the ability for dental floss and interdental brushes to actually scrape plaque away, giving an extra or enhanced contact point for more efficient removal.

For ‘most’ people a combination of the both works well if you are already in the routine of flosser a water flosser can further aid your oral health.

However, one of the biggest overriding problems is the failure of the general public to adopt flossing as part of the daily routine.

Best Water Flosser 2021 13

I believe Dr Terri Tilliss summaries the situation best.  “To achieve optimal oral hygiene, the key is an effective device that people will use long-term… since traditional string floss has negative associations, patients are often receptive to learning about alternatives. It seems futile to continue to hope for floss compliance in patients who have never developed daily flossing behaviors.”

But Dr Tilliss is not alone in his comments.  Hygienist Susan Clark remarks “One key to prevention is finding delivery systems and techniques that patients will feel comfortable performing on a daily basis. It becomes a win-win situation for the dental hygienist and dental patient when they work together as a team to find solutions for improved home care. “

If you want to know more, do check out Waterpik’s clinical research that is available.

Water flosser v manual flossing

Let’s be clear, the intention between both an electric water flosser and traditional string style floss is the same; to remove the plaque, bacteria and food debris that isn’t or wasn’t removed during brushing for a cleaner mouth and improved oral health.

However, water flossing typically has the benefits outlined earlier in this article that make it  a more appealing option than traditional floss.

Best Water Flosser 2021 14

Hygienist Jamie Collins writes at Dentistry IQ, “I have spent years encouraging many, many individuals who are not ever going to be flossers to try different products for interproximal care. Flossing is a hard habit to get into, and an easy one to drop. The key is to find something patients are willing to use. Through trial and error, I have found that one product does not work for all; if patients don’t like it, they won’t use it.”

She believes flossing is still the gold standard though.

Therefore, really the decision is personal, but if you are one who has not established a habit of flossing regularly already a dental water flosser might just be the answer to establishing a routine for good oral health.

Is water flossing messy?

Initially, yes, but with a little practice it is easily mastered.

If you try to look at yourself in the mirror when doing it, you may end up with a splashed mirror, water all over the sink and down your top.

Practice makes perfect and many products come with some good instructions.

The best way to show you is to watch someone else.

The following video from Waterpik gives a good demonstration.

How to Use a Waterpik® Water Flosser (UK)

What to look for in an electric flosser

The deciding factors with an electric tooth flosser are thankfully a lot less when compared to choosing an electric toothbrush.

Here are the key things you want to consider.  Different models may offer different features and box contents, so do consider what is most important to you.

  • Portability/Space

The first major consideration is whether you want or need a portable flosser.

A portable flosser works best if you do not have a power outlet in the bathroom (or any other room you intend to use it in) and if you travel frequently.

Another consideration at this stage might be surface space.  If you have particularly limited countertop or storage space for the flosser.

Countertop water flossers are generally better.

  • Water tank/reservoir size

Portable flossers have a small tank suitable for one, possibly two flossing sessions.

They will require refilling more frequently and can be a little more awkward to refill to, due to their shape and size.

A traditional flosser will offer a water tank that will last multiple cleans or allow for extended flossing time without fear of running out of water.

Waterpik for example, their cordless flossers hold up to 210ml and the countertop up to 1,000ml.

The amount of flossing timer varies on the pressure and size of tank, but as a guide.

  • 150 ml = 30+ seconds of flossing time
  • 210 ml = 45+ seconds of flossing time
  • 450 ml = 60+ seconds of flossing time
  • 650-1000 ml = 90+ seconds of flossing time

You can refill the reservoir to extend flossing time.

Best Water Flosser 2021 15
  • Adjustable pressure settings

Countertop water flossers will often offer a wider range of pressure settings from very soft through to a harder and more powerful water jet.

Measured in Bar the pressure there may be anywhere between 2-10 pressure settings from .68 through to 6.89 Bar.

Portable flossers do sometimes offer different pressure settings but this is often high or low rather than a more accurate level of control, typically measuring at 3.1-5.2 Bar.

  • Different tips

The more premium models, particularly those from Waterpik offer a range of different styles of interchangeable tips.

The range of tips are shown in the following image:

Best Water Flosser 2021 16
  • Classic jet tip – The Classic Jet Tip is the standard tip for everyday use. It cleans deep between teeth and below the gumline to help prevent gum disease and improve your oral health.
  • Plaque seeker tip – The Plaque Seeker Tip removes plaque around all types of dental work and hard-to-reach areas. It has 3 thin tufts of bristles that gently access stubborn plaque around dental implants, crowns, bridges and veneers.
  • Tongue cleaner tip – The spoon-like shape of the Tongue Cleaner effectively traps and removes bacteria from the tongue to help prevent bad breath.
  • Pik pocket tip – The Pik Pocket Tip is specifically designed to deliver water or anti-bacterial solutions deep into periodontal pockets as prescribed by your dental professional.
  • Orthodontic tip – The Orthodontic Tip has a tapered brush on the end to help remove plaque from braces and orthodontics. It also helps flush out bacteria and food debris from around teeth and under the gums.
  • Toothbrush tip – The Toothbrush Tip is similar to a manual toothbrush (it is not an electric or sonic toothbrush). It attaches to the Water Flosser handle and allows you to manually brush your teeth as you water floss.

  • Adjustable/rotatable nozzle

The neck of the plastic nozzle that comes out from the flosser will not normally be adjustable.  The plastic body of the nozzle tube itself will have been set during the design and manufacturing process.

However some models allow you to rotate the nozzle head to adjust the position and resulting angle allowing you to better target certain sports in the mouth.

The nozzle can often rotate a full 360 degrees thanks to a click wheel style adjustment.

  • Noise

Like an electric toothbrush the pump inside does make a noise.  This might not be something you want to use in the middle of the night if others are asleep around you.

The portable options tend to be quieter than a countertop option.

  • Timer/pacer

Select models have a built in timer like an electric toothbrush that helps ensure you floss for an equal amount of time in different parts of the mouth.

The suggestion is up to a minute spent flossing.

The pacer comes at 30 seconds via a pause in the flow of water and then again at 60 seconds.

  • Internal/removable battery

Mains powered oral irrigators are most powerful but if opting for portable options, think about the internal battery or removable battery if these are used.

How long will the battery last for, how quickly does it recharge.

Best Water Flosser 2021 17
  • Price

Naturally subjective you do in some respects get what you pay for.

You can pick up an electric flosser for less than $50.  For $80 you are on the road to a good quality product.

As a rough guide spending somewhere between $80-150 is going to get you a decent water flosser with a good range of features.

Spending more will likely result in diminishing returns for every pound spent, whilst spending less may leave you short of desirable features and quality might be an issue.

  • Colours

Some models come in a variety of colour options.  Sadly the choice is limited, so don’t go in expecting this as a feature.

With all this information in mind, what is the best water tooth flosser?

Replacement nozzles

It can vary from brand to brand, but the general advice, much like a toothbrush head is to replace the tip/water flosser nozzle every three months.

Most brands will offer spares that can be purchased, often in packs of two.

Best Water Flosser 2021 18

Multiple users

One of the benefits of most flossers is that the nozzles are detachable and interchangeable.

Waterpik offer the biggest range of nozzles/tips and make it easiest to actually change tips.

The ease with which they can be changed means one water flosser can be used between multiple people, but do ensure that tip is changed.

Water resistance

Always refer to the particular models instruction book for confirmation, but the handles of most flossers are water resistant and designed to survive exposure to water.

Cordless models are often safe to use in a shower, if you chose.

Do be aware that corded models are connected to power and have safety measures built in, but avoid excessive moisture and submersion.

At all costs avoid the plug coming into contact with water or touching the plug with wet hands.

Voltage and 2 plugs

Depending on the model you choose will depend on the exact power and connector that comes supplied with it.

All of those sold in New Zealand should come with a 2 pin power supply. Just be aware if you are importing from the USA, that you will likely need a plug adapter.

Best Water Flosser 2021 19

Cordless models will often have the same 2 pin connector on the charging stand, unless the model is powered by removable batteries in which case no charging stand will be provided.

If you intend to travel with the flosser be aware of the different power requirements internationally.  As a quick reference guide:

  • Printed on base/plug – 100-240V
    • Where can it be used? Globally
    • Do I need a voltage convertor? No
    • Do I need a plug adapter? Subject to country
  • Printed on base/plug – 220-240V
    • Where can it be used? In countries with 200-240V (e.g. Australisa, most European countries, NOT US/Canada)
    • Do I need a voltage convertor? Yes if the voltage of the country you are travelling to is less than 220V
    • Do I need a plug adapter? Subject to country
  • Printed on base/plug– 110 Volts 60 Cycles
    • Where can it be used? In countries with 110 volts (e.g. US/Canada)
    • Do I need a voltage convertor? Yes if the voltage of the country you are travelling to is higher than 110V
    • Do I need a plug adapter? Subject to country

Long term maintenance / replacement parts

Generally speaking a water flosser will need little in the way of replacement parts or maintenance.

They are designed to last several years and require little user involvement outside of doing their job.

Good practice is to wipe the flosser clean occasionally with a damp cloth and dry off excess moisture.

If not being used empty the tank/reservoir and allow it to dry.

Lukewarm water and antibacterial mouthwash can be used through the system to help kill off any germs and keep the system operational.

For those with lids look to place those on top of the tank to preserve the unit.

Best Water Flosser 2021 20


Subject to change between models and manufacturers, most come with a 2 year (24 month) warranty that will cover any faults that are not as a result of user damage.

An example might be the pump failing to push water through.

You will need to contact the manufacturers respective customer service line but will likely need your original proof of purchase and once accepted arrange repair or replacement of the product.

Where to buy

Due to the size and slightly more specialised nature of the electric flosser, sadly the availability is not quite as great as most other dental products.

You are less likely to see a wide range in your local supermarket, but chemists like Chemist Warehouse do offer them.

Many manufacturers offer their own online stores and then there are the other retailers like Shaver shop who offer a wide portfolio of products.
