Sensodyne Toothpaste Product FAQs


What is the #1 dentist recommended toothpaste for sensitive teeth?

Sensodyne® toothpaste is the #1 dentist recommended toothpaste for sensitive teeth. 9 out of 10 dentists recommend it for patients with sensitive teeth.

How do desensitizing toothpastes work?

Exposed dentin may become susceptible to triggers such as cold food or drinks. Sensodyne formulas work in two different ways: Sensodyne® toothpaste formula contains the active ingredient potassium nitrate and works at the source of the pain to calm and soothe the nerve.  Sensodyne® Repair & Protect formula contains the active ingredient stannous fluoride and builds a robust reparative layer over and within the exposed dentin tubules to create a barrier for pain triggers.  Each Sensodyne® toothpaste, with regular brushing, is proven to relieve the pain of tooth sensitivity. 

How often should I use Sensodyne toothpaste?

Use Sensodyne® toothpaste twice a day, every day, in place of your regular toothpaste for ongoing protection from tooth sensitivity.

How long will I use Sensodyne toothpaste before I notice less sensitivity?

Clinical studies show potassium nitrate progressively reduces the pain of sensitivity over a period of weeks. The potassium ions in Sensodyne® toothpaste surrounds nerves and stops them from firing. This means transmission of nerve impulses is prevented and the resulting pain can be relieved. Stannous fluoride containing toothpaste (e.g. Sensodyne Repair & Protect) provides lasting protection against the pain of dentin hypersensitivity (tooth sensitivity) following 4 weeks of use when used as directed.  Always read the label. Sensodyne® toothpaste should be used twice daily to help prevent the nerve response and relieve the pain of sensitive teeth. Sensitive teeth may indicate an underlying problem that needs prompt care.  If symptoms persist or worsen see your dentist.

Once I stop using Sensodyne toothpaste, will my tooth sensitivity return?

Whether or not the pain will return depends on the individual. To stop the pain from coming back, your dental professional may recommend replacing your regular toothpaste with Sensodyne® toothpaste and using it twice a day, every day.

Why should children under 12 consult a dentist before using Sensodyne toothpaste?

The Sensodyne® toothpaste variations for sensitive teeth are not formulated or recommended for children under the age of 12. Sensitivity is rarely a problem for children that young. Check with your child's dentist to get the proper recommendation.

Does Sensodyne toothpaste contain fluoride?

All Sensodyne® toothpaste variants contain fluoride.

Is Sensodyne toothpaste available as a travel-sized tube?

Sensodyne® toothpaste is available in a travel-sized tube in major retail outlets.

Can I use mouthwash after brushing with Sensodyne toothpaste?

Yes, you may use mouthwash or eat or drink after using Sensodyne® toothpaste.

What is the Relative Dentin Abrasion (RDA) for Sensodyne toothpaste?

All Sensodyne® toothpastes fall within the American Dental Association (ADA), Food and Drug Administration (FDA) and International Organisation for Standardisation (ISO) guidelines for daily use dentifrices. Typically, Sensodyne® toothpastes have low to moderate RDA in the range of 60-120, depending on variants (and market). Sensodyne® ProNamel® toothpaste has a low RDA value of approximately 35.

Do Sensodyne toothpaste tooth-whitening formulas actually bleach as well as relieve sensitivity?

Sensodyne® toothpaste whitening formulas do not bleach. They contain a matrix of polishing and cleaning ingredients which all contribute to the cleaning and whitening effect. Sensodyne® toothpaste variants contain clinically proven desensitizing active ingredients.

Is Sensodyne toothpaste safe to use during tooth-whitening treatments?

Sensodyne is for sensitive teeth. If your teeth are sensitive after whitening, you can use this product. Research has shown that using Sensodyne® toothpaste two weeks before and during the whitening process can significantly:

  • Reduce the chances that whitening related tooth sensitivity will develop.
  • Increase "sensitivity free" days during and after the whitening process.

How is Sensodyne ® Repair & Protect toothpaste different from the other Sensodyne® toothpaste?

Sensodyne® Repair & Protect toothpaste uses a different active ingredient. The active ingredient used in Sensodyne® Repair & Protect toothpaste is stannous fluoride, which builds a repairing layer over the vulnerable areas of your teeth, to protect from pain.
