Toothpaste for sensitive teeth

Toothpastes for sensitive teeth that work at the source — they seal exposed dentinal tubules with hydroxyapatite, rather than just numbing the nerve. All are SLS-free; most are fluoride-free (see the “Ingredients” filter).

Where does sensitivity come from?

Underneath the enamel is dentin, full of microscopic tubules leading to the nerve. When these are exposed, every sip of cold water results in an unpleasant “jolt.” Traditional toothpastes numb the nerve or temporarily block the tubules. Nano-hydroxyapatite fills them with your teeth’s natural building material — so the effect builds up gradually but provides long-lasting relief.

How to choose

PrevDent nHAp — 15% nano-hydroxyapatite plus potassium nitrate, offering both mechanisms at once; a good choice if sensitivity is bothersome and you want quick relief. PrevDent OrthoCare nHAp — the same pair of ingredients in a version for people with orthodontic braces, whose teeth ache after every adjustment. Ollie (Clean Mint, Strong Mint) — 10% nHAp and potassium gluconate with 11–13 ingredients; for those who want the shortest ingredient list possible. BOKA (Ela Mint, Cinna Mint, Lemon Lavender, Refresh Mint) — nHAp with no concentration specified; sufficient for mild sensitivity, with the most interesting flavors. LyDenti SMIYO Sensitive — hydroxyapatite and potassium nitrate in a whitening toothpaste; for those who want brighter teeth despite sensitivity. Results depend on regular use — evaluate them after a few weeks. More: what for tooth sensitivity, hydroxyapatite toothpastes.

Most common questions

How quickly does a toothpaste for sensitivity start working?

Potassium nitrate and nano-hydroxyapatite are ingredients used in toothpastes for sensitive teeth; studies have evaluated their effectiveness after a few weeks of regular use. Do not rinse thoroughly after brushing — the ingredients need to stay on your teeth.

Can I use sensitivity toothpaste permanently?

Yes. These are daily-use toothpastes, not a treatment with breaks.

Does whitening toothpaste worsen sensitivity?

It can, if it contains strong abrasives. PrevDent nHAp, BOKA Refresh Mint, and LyDenti SMIYO combine gentle brightening with care for sensitive teeth, without using peroxides.

I have braces and my teeth hurt after appointments — what should I choose?

PrevDent OrthoCare nHAp: potassium nitrate is an ingredient used in toothpastes for sensitive teeth, and nHAp supports the remineralization of the enamel surface around the brackets. Pair it with an alcohol-free OrthoCare mouthwash that doesn't sting.

When should I see a dentist?

If the pain is sharp, localized, or does not go away after a month of using the toothpaste — it could be a cavity, a crack, or gum recession, which toothpaste will not fix.
