Sensitive toothpastes can be hit or miss. S3 is different.

Calms, strengthens and protects sensitive teeth.
120+ clinical studies support the ingredients in S3.
Most sensitivity toothpastes just mask the problem. S3 goes after the root cause. It calms the pain, while also rebuilding the enamel and laying down a protective layer.

The only triple-active sensitive toothpaste
Sensitive teeth need three things. S3 is the only toothpaste that brings them together into one daily formula.
Results you can see. And feel.
Independently tested at the University of Reading

Dentine tubules are microscopic channels in the layer beneath your enamel. When enamel wears or gums recede, they are left exposed, and heat, cold and sweetness can reach the nerve inside the tooth. That is the twinge you feel as sensitivity.

With S3 you could feel less sensitive in 7 days. Next month? You've forgotten what sensitivity felt like.



Loved by people that used to feel sensitivity
Bought this because it said it was good whitening as well as sensitive. Would say it works great!
A good toothpaste with a pleasant taste thatchelped to aleviate sensitivity in my teeth after few days. I hoped that reminaliastion would improve opacity of teeth but it wasn't noticeable .
In my late seventies still with most of my own teeth, albeit with a history of tooth sensitivity. This new toothpaste has helped with that sensitivity, which during the recent warm spell has been a real blessing. I recommend it to anyone with tooth sensitivity, especially older folks.
This toothpaste is amazing if you have sensitive Teeth ,my teeth was so much better after 2 days using this , I can now drink hot / cold drinks without any issues, definitely worth buying, i will purchase again:)
Having suffered with sensitive teeth for as long as I can recall, I’ve ran the gamut of brands out there claiming to address the issue. At best, they tend to improve the situation rather than cure it. S3, which I’ve been using for about 6 weeks at time of writing, is in a different league. There was an almost immediate difference in how my teeth reacted to cold drinks, ice cream, etc., and it has only got better and better since then. It’s a strange position to be in now, where my reactions to previous triggers are simply psychological, rather than physical - I’ve got a lot of muscle memory and bad habits to unlearn! For anyone even thinking about trying S3, please do so - it’s no exaggeration to say it could well change your life. It is more expensive than those “sensitive” toothpastes to be found on the supermarket shelves but it worth every single penny. Buy smarter, not cheaper.
I do suffer from mild sensitivity sometimes and I am using S3 since 4 weeks because I was interested in hydroxyapatite toothpaste but didn't want to give up to fluoride. Tbh, the experience so far is WOW. My teeth feel so gentle and I started seeing also a better, whither color on the enamel. Sensitivity is also gone, but I am strongly surprised by the daily compounding effect on the general health of my teeth. Happy subscriber so far!!
Never actually experienced any benefit from sensitive toothpastes until using S3. I was trying Colgate sensitive because Sensodyne did nothing, but that was also pretty poor. As soon as I switched to S3 I was genuinely amazed at the difference!
I'm a 50yr plus mom of 3 living in the UK - that really looks after her teeth, however due to stress I've been clenching my teeth while I sleep which has resulted in my teeth being quite sensitive due to fine hairline cracks that have developed over the years. Despite using a mouth guard at night and using the usual toothpastes recommended by my dentist non have helped. (The likes of Sensodyne and other popular brands caused a burning sensation on my front teeth when I first applied them when brushing (due to the hairline cracks)! A few weeks ago I was on my social media when this advert for S3 toothpaste came up on my feed, and out of desperation I decided to give this toothpaste a go. I am SO happy that I did! I have been using the S3 toothpaste for over 2 weeks now and Honestly - WHAT A DIFFERENCE! I now no longer flinch when I start brushing my teeth as the sensitivity has gone. It's so good that I immediately ordered another and I've just received my second tube a few days ago, as I never want to be without it, and will always have one spare in the cupboard. The peppermint taste is very pleasant and not overpowering and my teeth are not only desensitised but clean and naturally white. (I don't drink wine and generally try and stay away from foods that stain my teeth). I can HIGHLY recommend using the S3 Sensitivity Science. Not only will your teeth feel AMAZING but the customer care and attention to detail is FIRST CLASS! The team genuinely care and have been in touch making sure that the S3 is working for me. What a BRILLIANT company and thank you for developing a toothpaste that WORKS. You have a customer for life! THANK YOU!
Been using it for a couple of months now and i genuinely can’t remember the last time I had sensitivity and my teeth are quite worn down in places. Will be my main toothpaste going forward definitely.
This amazing S3 toothpaste is incredible it's designed for sensitive teeth. I have tried this and I no longer have to take cold items out of the fridge for a couple of hours. It definitely helps with sensitivity, I'm not saying it's completely gone but the longer I use i believe it will. My tube has lasted weeks think its time to order. Great quality
Excellent product. I had been suffering with sensitivity with one of my back teeth due to an exposed nerve. I had tried other branded sensitive toothpastes but nothing really helped. I came across S3 on social media and thought I would try it. I'm so glad that I did, it's really has made a difference. I have just purchased again and will be making this my new regular toothpaste
Excellent toothpaste! Highly recommend.
This is a pricy toothpaste, but worth every penny! I have quite badly receded gums, and even looking at ice cream made me feel funny. After using this tootpaste for just over a month, the other day I had a whole tub of Haagen Dazs without any issues, so I can definitely say it works!
Fantastic toothpaste, genuinely feel like it's strengthening my teeth
So grateful to have finally found a toothpaste that actually helps with my sensitivity. After a few uses only, the difference on my teeth was noticeable. The S3 website is also very well designed and with thorough information about how the toothpaste works, good pricing and significant savings when subscribing.
Wow this is great- game changing for my sensitive teeth!
First question - worth it? Hell yeh it is! Does every single thing it says it does... as quick as it does. I'm converted!
Great product. On my second tube and love it. Sensitivity all gone, teeth feel clean and fresh.
The company contacted me before the package arrived today it was on its way, they then wassap me as it arrived and gave me tips and advice, a founder then reaches out on some questions, and then the product started working, have only been using a week and its 100% making a difference, and the customer service is refreshingly, jenuine great people to deal with, with a great product
I love the unique taste of the toothpaste. The packaging was premium quality. I tested this for three weeks on my sensitive teeth and the improvement was immense. No more sensitive teeth when eating ice cream ice poles or even biting an apple. Highly recommend this product my teeth felt really good.
Great taste and teeth feel great. Had a small problem with my order but they resolved it the next day - can’t ask for anything more
Good quality, definitely felt like my teeth respond to this better then what I've used before
Great toothpaste - they don’t talk about the whitening enough, my teeth have never looked better! Leaves teeth feeling like you’ve just been to the hygienist, love it
Helped my sensitivity more than anything else I’ve tried before
Lucky enough to try pre launch and so impressed with the results. Such a positive impact on my sensitive teeth. Cant wait to get my hands on some more.
I couldn't believe my luck after trying this for 2 weeks to find out that my sensitivity are completely gone. I'm not even joking. I've never found a sensitive toothpaste that actually delivered 100% sensitivity protection to hot and cold. I did find that the original price point of £19.99 was way out of my budget. But my next subscription thankfully was £14.99 which is way more affordable. Based on the research I've done considering the amount of work that they've done to produce this, I think it's a reasonable cost. Although I do think for a toothpaste, it is still overpriced. But I am over the moon with the results and as I can't find anything else that solves my sensitivity as good as this, I'm more than happy to pay it for now. The customer service has been absolutely outstanding. I can't fault them at all. Every time I've emailed them I've had a reply within 24 hours. It's always been a friendly response and very helpful service.
Incredible! I grind my teeth at night and get sensitive to hot things especially. Been using S3 for the last month and have really noticed the diffeerence - no sensitivity at all it’s incredible
I have never found a toothpaste for sensitive teeth that delivers what it promises until now! I have been using S3 for a couple of months and I no longer worry about cold or hot foods and drinks. The results are truly amazing and I promise that is not hyperbole!
So I’ve been using S3 for 3 weeks or so and it’s a revelation. I’d pretty much forgotten about sensitivity and I’d swear my teeth are shinier too. Certainly feel smoother
The packaging made me feel like I was sampling luxury. Even the tube itself with the lid was different from others. The toothpaste was a little wetter than I was used to but the taste was great and it did the job! Will definitely get again.
I've tried many other products for my sensitivity before, and after a while they sort of loose its effect on me. I have been using S3 for a while, and it just keeps working. Being able to drink cold drinks without worrying about it is such a relief.
I received this as part of a product testing campaign, the toothpaste was lovely and really helped keep my teeth clean.and fresh x
Recently had a filling done in a back tooth, so my dentist told me to buy a specific toothpaste. didn’t like the smell and was complaining so my girlfriend bought me this one…I have to say it’s not cheap but I’ll buy it again since it does the job and sensitivity overall is much much better. Recommended!
I have always had sensitive teeth and I’ve seen a noticeable difference from the first time I tried S3. It’s a product that I will continue to use. I have caught by the marketing and it’s really exciting to find a product that really lives up to it! Something that will be a staple in my bathroom for years to come!
I thought I’d experiment with new toothpaste after some slight sensitivity and this toothpaste has massively helped. Took a week or so but haven’t had any sensitivity since . Would rather not subscribe but they do a discount
I have some mild sensitivity that comes and goes and I wanted a toothpaste to treat this plus protect them in the future. S3 toothpaste has been great at this, no more sensitivity and it leaves an amazing fresh feeling after using. Would highly recommend.
Noticeable reduction in sensitivity
Fantastic, this product is simply fantastic. I suffered from tooth sensitivity for decades, tried anything offered in the market, included treatments recommended by my dentist. Nothing ever worked or only marginally did. The effectiveness of this toothpaste came as a surprise and overcame any optimistic expectations. Soon after starting regular use, I surprised myself enjoying hot coffee and ice cream without that constant background of pain that ruined every bite, every sip. I am still in pleasant disbelief.
This Toothpaste has definitely reduced my teeth sensitivity to hot and cold stimuli. I still get some sensitivity to sweet stimuli but this has significantly reduced in frequency and intensity. Lovely minty flavour and doesn't feel overly harsh on my teeth
From the very first brush my teeth felt and looked visibly stronger and protected.They felt smoother and my sensitivity lessened day by day.It was like I had a protective film over my teeth that was rebuilt my enamel and enabled me to enjoy both hot and cold food and drink without pain...I would highly recommend it.
A great toothpaste that I found helped with my sensitive teeth. It has a nice texture and not overpowering taste. I think it is quite expensive but I did like the toothpaste.
This is a good toothpaste and it certainly works to protect my sensitive teeth. I can't say I've seen a huge improvement in the appearance of teeth so no sure it's worth the money but perhaps it needs more time to work it's magic
Great toothpaste for sensitivity. After a couple of uses I noticed my sensitivity had improved. Teeth felt clean after use and a little went a long way. The only downside was the flavour was not too strong and I would prefer more of a minty taste but that’s just personal preference. For sensitivity I would recommend.
The toothpaste was good leaving me feel fresh and clean after brushing. Not harsh on my sensitive teeth and gum. Definitively would repurchase and recommend to family and friends.
Brilliant toothpaste used for recommended time and seen a use difference in the shade of my teeth colour will definitely continue to use.
Looks lovely straight out of the box, luxurious toothpaste and I love how they included instructions on what will happen each week you use etc. I loved that it’s backed by a dentist and has many benefits-more than usual toothpaste. Taste is ok, it’s not like super fresh but it’s pleasant. I wasn’t sure about the tube material-sometimes you have to really squeeze it as product gets stuck on top I really liked receiving an email after 1 and teo weeks saying what’s happening to my teeth by then etc
I have had sensitive teeth for over 2 years after using this for 2 days I see the difference straight away its brilliant i can now drink hot & cold drinks and no pain or discomfort, i wish I knew about it before as I would of give it a go ,I have tryed different ones in the past but this one is by far the best :)
Amazing toothpaste, perfect for my over sensitive teeth. It really does make a difference. The only downside is the price as it’s quite expensive so may not be able to purchase anymore.
Move out of the way all you other sensitive toothpastes - they all sort of work, after a while. This is a game changer, not only does this stuff work - it works right away. Tastes great, feels great on the teeth, dentist complimented them as well. AND looks great, superb packaging, easy to apply, lasts ages. I will not be switching back to the other stuff!!!
All in all, I like the flavour of the toothpaste. Its not overpowering yet still left my mouth and breath feeling fresh and clean. Its not incredibly foaming, which I preferred, as I felt I could really spend the right amount of time on brushing without feeling the need to spit One thing I would think could improve is the product appearance, its slightly opaque and gloopy like which was a little off putting
