Sensodyne Repair & Protect toothpaste

By Sensodyne

A toothpaste for sensitive teeth built around NovaMin. As with any sensitivity toothpaste, you need to keep using it for the effect to last, and persistent or one-tooth sensitivity should be checked by a dentist.

Can be useful for

A product can support daily care but can’t treat a dental problem on its own. See a dentist if symptoms persist.

Choosing toothpaste

  • Check the fluoride level (ppm) on the pack – at least 1,350ppm for adults.
  • For children: a smear for under-3s and a pea-sized amount for ages 3 to 6.
  • Sensitivity toothpastes need continued use to keep working.
  • After brushing, spit out but don't rinse.
  • See a dentist if sensitivity is severe, lasts weeks or affects one tooth.
