Look for the American Dental Association Seal of Acceptance. This means the sensitivity toothpaste meets their criteria for effectiveness and safety, and the vendor has paid to display the seal.
Also look for
- A product specifically designed for sensitive teeth
- Potassium nitrate or strontium chloride in the ingredients’ list because, over time, these help your teeth’s nerve endings block stimuli
- Components that balance the pH of the toothpaste so that it is not acidic
Look for and avoid
- Claims of teeth-whitening or special abrasive polishing ingredients that could further harm your already sensitive teeth
- Any allergens or chemical sensitivities you known about (for example, some tartar-control toothpastes contain triclosan, which is an allergen for some)
Whatever product you choose, remember it may take several weeks to notice a decreased sensitivity of your teeth.
