Please note: The name of this product may include ‘whitening’, but this mouthwash will not change the natural colour of your teeth.

At best it can remove external staining on the tooth surface, lifting discolouration and revealing the natural tooth colour, that may have been hidden, therefore gaining a whitening effect.

It cannot change the natural tooth colour, you require professional tooth bleaching/whitening for this to happen.

We explain this further in our post Best Whitening Mouthwash: Does Such A Thing Exist? and we also explain teeth whitening more generally in our simplified overview of teeth whitening.

In this review, I am taking a detailed look at Ultradex Sensitive Recalcifying and Whitening Daily Oral Rinse (view on Amazon).

It promises to protect teeth and gums, restore natural whiteness and eliminate bad breath instantly, but does it live up to these claims? We’ve put a fair few mouthwashes to the test now, and we’re keen to see how Ultradex compares to the others.

We start off with a brief summary of our findings, but for those that like the deep dive we’ll be going into all the details further down the page in our full Ultradex Mouthwash Review.

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

Does it actually work?

Yes in part it does but the impact and results will be different for different users.

I didn’t notice any visible whitening (or what is essentially stain removal) over the time I used it, but I feel my teeth are as stain free as they will ever be.

I did feel the effects of the recalcfying process though which was good. I got that dentist fresh and polished feel.

If you have never before focused on making your teeth appear whiter, and know that you have staining on the exterior surface of your teeth, then this used in conjunction with a good toothpaste, may enhance the results, but the mouthwash is not required for stain removal.


How much does it cost?

For a 250ml bottle, the cheapest price I found it for online was £5.99, but the usual price for it elsewhere is about £7.50.

I worked out that after purchasing a 250 ml bottle of this oral rinse, it would last you 8 days, if used twice daily. From this, I calculated that providing the suggested dose is being used (15ml) twice daily, to use the product would cost you 90p per day, which is very expensive.


Where can I buy it?

There are currently only a few sellers that stock this product. Ultradex can be purchased physically from Boots retailers or online from Amazon.


Would I recommend it?

Although it comes in smart looking packaging and felt like it was doing its job of recalcifying my teeth, I would not recommend it for everyone.

This is because in my opinion there are not enough benefits to justify spending that amount of money to use it daily.

It runs out very quickly, so you would have to restock it often and this will be pricey as you pay a lot for the amount you get in each bottle. In addition to the price issue, the freshness provided is not overly noticeable.

Full Review

Many of use desire whiter teeth. The Ultradex Sensitive Daily Oral Rinse claims to ‘recalcify and whiten teeth’, restoring the calcium compounds on your teeth and making them visibly whiter.

The product packaging states that the oral rinse was developed by Dental Professionals and with a leading UK university. Following further research into this, I found out that The Queen Mary University and Barts University were the two used throughout the development of the range of oral hygiene products.

This product whitens teeth by oxidising stains such as tea, coffee and wine. The oral rinse has hydroxyapatite crystals in it that fill in any microscopic cracks and create a smooth surface, as well as reducing adherence of further stains.

All sounds very fancy hey? Let me be clear here, this mouthwash does not change the natural colour of your teeth.

At best it helps remove surface staining to make the teeth appear whiter, but you will never get the effect achieved by professional teeth beaching.

The mouthwash is to be used twice daily in addition to brushing.


How I tested the mouthwash

It was suggested that this product was to be used twice a day at a dosage of 15ml per use (30ml per day). I rinsed the mouthwash around in my mouth for 30 seconds and spat it out when done.

For maximum effect, it was recommended that I was to use it 30 minutes after brushing, before eating or drinking anything.

The solution needs to be shaken before use, which is a first in my experience for a mouthwash.  What was a clear water like liquid changed to a chalky white colour as the bottle was shaken.

It was also stated that using the product at night-time before bed was especially effective as it gave the product time to work overnight as I was sleeping.

Alongside using this product I kept to my daily routine of using an electric toothbrush with a Crossaction brush head in the morning and evening as well as a daily floss.

I tested the Ultradex Sensitive Recalcifying and Whitening Daily Oral Rinse for two weeks.


Summary How I tested the mouthwash

  • Twice daily
  • Two weeks (14 days)
  • 15ml per use
  • Normal brushing routine kept
  • Flossed once a day

Daily Usage

The box the mouthwash comes in is primarily white with green design highlights and is labelled as being ‘mint flavour’.

The colours used on the box make it look very elegant and professional.  The bottle itself which holds 250ml of the mouthwash keeps a similar design and looks very ‘clean’.

It also says the mouthwash is ‘clinically proven technology’.   When researching this claim it transpires that 9 out of 10 people with sensitive teeth reported to have preferred this mouthwash over others. Only 66 people took part in the trial!

Having shaken the rinse and poured what I think to be 15ml into the cap, I swirled the chalky solution around my teeth and gums for 30 seconds, I noticed no tingling or burning sensation, just a slightly granular taste.  It did not taste completely smooth, but if there were any small bit in the rinse it was not obvious. This wasn’t terribly noticeable and I wouldn’t say it made the taste all that unpleasant.

Even though there was a lack of burning or tingling, I did feel like the mouthwash was still working as it should. I was unable to tell whether this actually had an effect on my teeth, or whether it was just psychological. Either way, my teeth felt noticeably improved after use.


I felt a bit like I had just had my teeth polished by my dentist. You could feel smoothness when running your tongue along your teeth. I put this down to the reclacifying effect that the product had promised to give.

The recommendation is to use twice a day, which is fine but you don’t get much from the 250ml bottle when using 30ml each day.  Add to that the silly design of the cap and the lack of ability to easily measure the dosage and it takes the shine off this oral rinse.  Yes, I could get a teaspoon and measure or just ‘judge’ it better but these are small hassles.

For a 250ml bottle, the cheapest price found was online for £5.99. At the majority of outlets, the price was generally around £7.50.

With 2 x 15ml dosages per day, a 250 ml bottle of this oral rinse lasts you 8 days.

This makes the cost some 90p per day, which is quite expensive, no matter your financial income.

Whether this is really worth it for you is personal opinion.  I would say if you are not put off by this cost then give it a go.


So having rinsed the mouth with the rinse it does provide a mild freshness that felt like it was doing its job. The freshness dulled after a couple of hours, but still gave a fresh breath for longer.  Confirming that it lasted 12 hours is not that easy, it may have had an effect but on the face of it, I think the effects perhaps lasted for around 6-8 hours.

I made the effort to use it as was recommended, using it at night time to make the effects more beneficial. I would personally suggest that you wait a short while after using it to eat or drink anything so as to avoid any unpleasant tastes or running the risk of ruining the effect the mouthwash is having.

The mouthwash contains no alcohol but does contain fluoride of approximately 0.06% – This is part of the Sodium Monoflurophosphate which is calculated at 660PPM (parts per million) and this is used to strengthen teeth.

The full list of of ingredients:

Aqua, Hydroxyapatite, Glycerin, PEG-60 Hydrogenated Castor Oil, Polysorbate 20, Sodium Monofluorophosphate, Aroma, Cellulose Gum, Sodium Saccharin, Trisodium Phosphate, Sodium Chlorite, Menthone Glycerin Acetal, Sodium Benzoate, Sodium Citrate, Citric Acid, Gellan Gum, Sodium Bicarbonate, Limonene, Linalool.

Such makeup means that there is no alcohol in the mouthwash, it is gluten free and it is suitable for vegans too.

As far as safety instructions go, it is stated that the product is not to be used by children under the age of 7, and shouldn’t be swallowed by anyone. It also says that the bottle shouldn’t be stored or put in direct sunlight. The product should be used within 12 months of opening.

And for those who like to support the UK, it is made in the UK!


Summary of Daily Usage

  • Professional packaging
  • Clear in colour until shaken before use at which point it becomes chalky white
  • No easy way to measure the rinse
  • A minty taste that isn’t too overpowering
  • 2 x 15ml doses rinsed round the mouth for 30 seconds
  • 250ml bottle lasts for approximately 16 uses
  • 1 use will cost you 45p – so 90p per day if using twice as recommended
  • Lasting fresh breath

The Results

The Ultradex Sensitive Recalcifying and Whitening Daily Oral Rinse provides freshness and recalcifying of the teeth. A “dentist-clean-feeling” could be felt after using the mouthwash; my teeth felt smooth where the recalcifying process had taken place.

The whitening effect that is promised from the product wasn’t noticeable in the 2 week trial period, however, this may be a benefit that takes 6+ weeks to take full effect.  But do remember, this whitening is really only stain removal, which can be achieved much more cost effectively with a good toothpaste.

Overall I think the price is a massive factor influencing the value of this product. It is very expensive to buy compared to others on the market and you only get 8 days’ worth of use of it. There aren’t enough benefits to make the product worth purchasing and using on a daily basis for me.

For the level of usage recommended (twice daily), it really needs to come at a cheaper price tag.


Conclusion, is Ultradex Sensitive Recalcifying and Whitening Daily Oral Rinse any good?

The recalcifying process could bring advantages for those with sensitive teeth.

A study, albeit a little weak, has found that there are those who would recommend this over other oral rinse products.  Not suffering from such sensitivity issues I cannot justify or endorse the claims that this really works better, but if you have yet to find a product that works, this could be worth testing despite the cost.

The cost does put me off a little, but despite that, there are parts to this rinse such as the chalky taste and the feel post-use that does make me feel that it is doing something more than the cheaper options, even if I was unable to really see the benefits within the 2 week test period.
