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 running through the layer beneath your enamel. When they sit open, heat, cold and pressure reach the nerve inside your tooth — the twinge you feel as sensitivity. Sealing them helps block that signal at the surface.

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
Been using it over a year now. Teeth stay comfortable, strong and bright. Wouldn't use anything else.
And I've tried them all. Nothing else stopped the pain like this. Just wish I'd found it years ago.
Tried Oral-B and Sensodyne, both dearer and less effective. This is my new staple. Relief and great value.
Loving the whitening effect, my teeth have a proper glow. And the sensitivity I bought it for is gone.
Two benefits in one. Cold sensitivity settled and there's a lovely shine to my smile. Really happy overall.
Not only calmer teeth but a noticeably brighter smile. Lovely glow after a few weeks. Really pleased.
Was spending a fortune on sensitivity toothpaste. This costs less and works harder. Only wish the tube was bigger.
Big coffee and red wine drinker. Used to pay for it. Now no twinges and teeth look brighter too.
Walking outside in winter made me gasp. That's completely stopped. Can't quite believe a toothpaste fixed it.
I actually order iced drinks now without a second thought. Something I couldn't do for years. Brilliant stuff.
No nonsense, no gimmicks. Brushed twice a day for a month and the sharp pain is basically gone.
Noticeably less see-through at the edges of my teeth. They feel stronger and the sensitivity has faded right down.
My teeth used to feel fragile. Few months in they feel solid and the sharp twinges have vanished.
Ice water used to make me wince. Two weeks with this and that sharp jolt is just gone. Wish I'd switched sooner.
I'd almost given up trying different brands. This one actually delivered. Sensitivity down noticeably within a fortnight.
Doesn't feel harsh like some sensitivity pastes, but the results are stronger. Teeth calm and enamel feels healthier.
First week was subtle, but it keeps improving. By month two I'd forgotten I ever had sensitive teeth.
Teeth are visibly brighter and the sensitivity's gone. That extra shine has made me smile more. Love it.
Nothing flashy, just reliable daily relief at a fair price. My teeth have been comfortable for months now.
Cheaper than the big brands and works better. My whole family uses it now. No complaints at all.
Tea then cold water used to be a nightmare combo. Now nothing. My teeth just feel normal again.
I gave up ice cream years ago because of the pain. Not anymore. Total game changer for me.
Testing it with a glass of iced water every week. From wincing to nothing in about a month.
Dentist said my enamel was thinning. A few months on this and my last check-up was the best in years.
First coffee of the day used to be agony. Now I don't even think about it. Brilliant.
The scale and polish used to be torture. This year it was completely painless. Says it all really.
Random jolts of pain used to catch me off guard. Haven't had one in weeks. Such a relief.
Give it time. Three weeks before I really noticed, but now it's transformed how my teeth feel daily.
Bought it for sensitivity but my teeth look noticeably brighter too. Lovely shine and glow, and no more zingers with coffee.
Used Sensodyne for years and still flinched at ice cream. This actually stopped it. Different league honestly.
Honestly bought it for sensitivity, but the whitening surprised me. Real shine and glow, and coffee stains fading too.
Three wins really: no more cold twinges, stronger enamel and a lovely shine. Didn't expect all three honestly.
Does exactly what I need without the premium price tag. Sensitivity gone within weeks. Can't ask for more.
Half a year of daily use and my teeth feel rock solid. No sensitivity, no relapse. Part of my routine now.
Didn't think a toothpaste could really help. Proven wrong. Cold drinks no longer make me flinch at all.
Didn't notice much week one, nearly gave up. By week three the cold-air twinges had properly settled. Glad I stuck with it.
Sugar used to send a jolt through my back teeth. Gone now. Eating whatever I like again.
Colgate Sensitive never really cut it. Two weeks with this and the difference is night and day. Won't go back.
Smoother, stronger, no more wincing at cold. Took a few weeks but the wait was completely worth it.
There's a smooth, strong feeling after brushing, like a protective layer. Sensitivity gone and enamel feels tougher.
Kept a little diary. Week one nothing, week four better, now at eight weeks totally pain free.
Came for the sensitivity, stayed for the whitening. Teeth have a real shine now and the cold twinges are gone.
Bought one tube to try, now everyone uses it. Great value and my husband's sensitivity has completely settled.
Years of avoiding cold and hot foods. Three months on this and I eat and drink freely again. Life changing.
Sensodyne prices had crept up for less effect. Swapped to this, better relief, kinder on my wallet.
Tried loads of expensive sensitivity brands that did nothing. This one actually works and costs less. Genuinely great value.
