Biotene Mouthwash Review

Biotene Mouthwash

Today I will be testing the Biotene, which is a mouthwash especially for people who are suffering with a dry mouth. It promises to give the mouth ‘soothing moisturisation’.

For a more detailed comparison of choices and to learn more about mouthwash, see our best mouthwash post.

Does it actually work?

Yes, it works best for those with diagnosed ‘dry mouth’ and suffer with such as a result of medication.

For those without such, it does offer some, but limited benefit.

How much does it cost?

At the time of the writing the cost is around or just below £8 per 500ml bottle.  Although online retailers like Amazon (view Biotene on Amazon) do offer bundles where there are cost savings for buying multiple bottles.

Unfortunately Biotene is not available to purchase at places such as supermarkets, for example Tesco, and can only be purchased through drug stores or websites online.

For the quoted price you get a 500ml bottle of the moisturising mouthwash.

The price of the oral rinse doesn’t vary all that much depending on the location of purchase, however if you want to purchase it for the cheapest possible price, going online is definitely the recommended method.

Where can I buy it?

As I mentioned before, this product is not available to purchase in places such as local supermarkets, or corner shops and has to be acquired in bigger drugstores.

So far, the only places the mouthwash can currently be purchased is from the following; Amazon, Superdrug and local pharmacies, including Lloyds Pharmacy.

Buying online will give you option to have Biotene delivered to you if that is the method you would prefer.


  • Does what it should
  • Nicely designed bottle and packaging
  • Alcohol free
  • Helps with things such as mouth ulcers as well as dry mouth


  • The taste isn’t as nice as normal oral rinses
  • The texture was off putting
  • More expensive than some other every-day mouthwashes
  • Doesn’t smell very pleasant
  • There were no cap measurements so a spoon was needed
  • Not sold in lots of outlets
Biotene Mouthwash Review 1

Would I recommend it?

I would recommend this if you are willing to pay for a bottle on a regular basis. If you are thinking about using it often and think it would benefit you a lot, it may be worth the investment.  It is of particular interest to those with medically diagnosed dry mouth or those who appear to suffer as a result of particular medication.

There aren’t many other cheaper options for this sort of rinse, and Biotene seems to be the most popular one with the best customer feedback.

It does what it should, but for the price you pay, I would expect it to work a bit better than it actually does.

Biotene Mouthwash Review

Full Review

No one wants their day to be ruined by a dry mouth. If you are brushing your teeth and keeping yourself hydrated but still find yourself suffering with a dry mouth maybe Biotene is the rinse for you.

This mouthwash for dry mouth can help relieve dryness and also help to sooth any oral irritations you may be suffering from such as mouth ulcers and denture sores.

The moisturisers and lubricants in Biotene, replace and aid your natural saliva production to reduce the feeling and effects of dry mouth.

Biotene is a company dedicated to providing relief for dry mouth by providing a range of products. These include sprays, gels, oral rinses and toothpastes. They have a very informative website which tells you more about what they offer.

This is an everyday mouthwash that can be used safely a couple as many times a day as you like for as long as you like.

How I tested the mouthwash

The guidance from Biotene (view on Amazon) is to rinse 15ml (one tablespoon) around the mouth for 30 seconds up to 5 times a day.

For the purposes of this review the times I tested the mouthwash as follows:

  • In the morning as soon as I wake up, about an hour before I brush my teeth
  • In the evening, around 5pm
  • Before bed, a little while after brushing my teeth

Each time I used the recommended 15ml dosage.

This test lasted for 10 days.

In line with this my normal tooth brushing pattern remained, cleaning my teeth twice a day for 2 minutes with an Oral-B electric toothbrush with Oral-B 3D White toothpaste.

It should be noted that I do not suffer from dry mouth and this review is based on personal testing along with feedback from those that do suffer from such and their experience of Biotene.

Summary of how I tested the mouthwash

  • Test lasted for 10 days
  • Used at 3 different times of the day
  • Used 15ml each time
  • Used Oral-B electric toothbrush with Oral-B 3D White toothpaste
  • Cleaned twice a day for 2 minutes each time
  • No changes in diet

Daily Usage

Biotene dry mouth oral rinse is here for you whenever you need a blast of moisture.

The mouthwash is clear and has a weak smell to it. The smell isn’t as pleasant as other types of mouthwash, it smells faintly of mint, but it isn’t enough to make it smell appealing in any way.  However, it’s not about the smell, it i about how it can improve your dry mouth.

Biotene Mouthwash Review 2

When I first tested to the rinse, I found the taste was nowhere near as pleasant as other mouthwashes I have used in the past. It tastes very similar to how it smells. I did find that after a few uses I grew more accustomed to the taste. The texture is also not very pleasant, as it has a slightly thicker consistency to regular mouthwash, but I also found I grew more accustomed to this too as I used the product more and more.

To someone who does not suffer with dry mouth this feeling is unusual but the thicker consistency come as a welcome relief to a mouth feeling dry.

The initial taste when you first put the mouthwash into your mouth is quite a dull one, there is a slight hint of mint, but not much. As this is a mouthwash made for moistening the mouth and not killing bacteria, it had less of a kick than regular mouthwashes. There is a slight tingling sensation on the tongue, but this is quite weak. Throughout the entire 30 seconds it is to be tested for, the taste or the intensity doesn’t really change that much.

Once spat out, there is a noticeably thin layer of lubrication around the mouth and a slightly numb sensation to the tongue. The aftertaste is a little bland and unpleasant and makes me want to use another mouthwash to freshen my breath.

This thin layer of lubrication is the Glycerin that bonds with water to form a thicker, moisture rich layer in the mouth similar to the naturally occurring saliva.

The ingredients in the mouthwash are Aqua, Glycerin, Xylitol, Sorbitol, Propylene Glycol, Poloxamer 407, Sodium Benzoate, Hydroxyethylcellulose, Methylparaben, Proplparaben, Aroma, Sodium Phosphate and Disodium Phosphate.

This mouthwash is alcohol free.

Biotene Mouthwash Review 3

The recommended dosage is 15ml. Swish this around the mouth for about 30 seconds and then spit out.

From the 500ml bottle will get approximately 33 uses out of it.  If you then use three times a day you are getting about 11 days use from the bottle.

If you ever receive advice from your dentist or hygienist to alter your routine do take their advice.

As with any product used within the mouth, should you notice any side effects stop using and seek further assistance.

It is not advised for children under the age of 12 to use this mouthwash for dry mouth.

This works out to be quite an expensive investment as it works out the mouthwash will cost you roughly 24 pence per use, which a lot of money for only one use. This is if you use it only 3 times a day, however the bottle suggests you can use it up to 5 times a day, and doing this would mean the bottle would only last you approximately just under a week and would cost you a lot more as you’d have to purchase a new bottle every week.

This is not me saying do not use this product, this is just my personal opinion and the different costs I calculated.

Biotene Mouthwash Review 4

Suffering from a dry mouth can be irritating and uncomfortable, so it is understandable to want to find something that will help. Biotene may not be the cheapest option, but if it the only thing that works, it may be worth the investment.

Retailers like Amazon do offer bundles that include multiple bottles at a cost saving (Buy Biotene on Amazon).  Buying just 3 bottles at the same time allows the per use cost to come down to 17 pence.  Thats pretty reasonable cost saving just for buying a couple of extra bottles, that you are likely to use anyway.

The bottle isn’t very fancy looking, and looks more clinical than anything else. This isn’t a bad thing though as it makes it look very professional. The design is simple, and is not too busy looking so you can clearly see its purpose.

The font is very large on the front so it is easy to read however it is a lot smaller on the back, making it hard to read things such as safety instructions and ingredients.

Speaking of safety instructions, there isn’t as many as normal mouthwashes usual have, however this can be expected as the purpose of this mouthwash is different to the more common ones and it doesn’t contain any potentially dangerous substances like alcohol.

Once removed, the cap has a large cup like design. Inside the cap there are no measuring lines, and the only suggested method of measuring is a tablespoon. The cap and bottle are both made of a smooth plastic, making it hard to grip sometimes, especially when wet.

Biotene Mouthwash Review 5

Overall Biotene dry mouth looks very professional and although not the best designed, may be worth a shot if you are suffering from a dry mouth and have yet to come across a product that works for you.

Summary of Daily Usage

  • Transparent in colour
  • A dull taste, with a numbing sensation
  • Didn’t smell any better than it tasted
  • 3 x 15ml dosages rinsed and gargled in the mouth for a 30 seconds then spat out
  • Lid has no measuring lines in for controlling dosage of mouthwash, so a spoon is needed
  • The lid is a bit small and hard to grip
  • Smart and professional bottle
  • 500ml bottle offers approximately 33 uses
  • 1 use can cost up to 24p

The Results

This mouthwash for dry mouth was designed to help moisturise and help sooth oral irritations.

I could feel that my mouth was considerably less dry after use, however this didn’t last for as long as I was expecting it to, but I do not suffer from dry mouth.

The feedback from those suffering is on the whole considerably more positive as if this is almost some kind of miracle product.  Conditions such as dry mouth can really affect well being and to have something so simple improve this is great.

Biotene Mouthwash Review 6

You would have to use this up to 5 times a day like the bottle suggests to maintain a moisturised mouth throughout the day. This is quite inconvenient if you work or go out during the day as it means you would have to carry it around with you and the bottle is quite big and heavy.

The moisturising effect lasted for about 90 minutes after use, for me, but could be greater for you.

Conclusion, is Biotene dry mouth mouthwash any good?

Aside from how expensive it is to continually use this product and the not so pleasant taste of the mouthwash, I see no reason not to try it out if you find you are suffering with a dry mouth on a daily basis.

If you find it works for you and you can afford to continually purchase this on a regular basis, you should definitely invest into this product. If you find it is not working for you, maybe try another one of Biotene’s range of products that you may find more suitable. If you find it is too expensive to keep continually buying, maybe look on the market for a cheaper alternative that still does a good job.
