Sensitivity toothpastes are one type of treatment to reduce tooth sensitivity. You can find common toothpaste brands in many stores that people have found to be effective.

Sensodyne Toothpaste to Reduce Tooth Sensitivity

According to Consumer Research, Sensodyne is the favorite for dealing with sensitive gums and teeth. People report that regular brushing decreases sensitivity. Sensodyne Repair and Protect Toothpaste is ADA approved and also contains the active ingredient of stannous fluoride, which is an anti-cavity forming substance.

Colgate Sensitive Complete Protection Toothpaste

Another toothpaste with positive feedback is Colgate Sensitive Complete Protection Toothpaste. It and Sensodyne both contain potassium nitrate, which is the substance that builds up tolerance for cold and hot foods and drinks.

Aquafresh Sensitive Toothpaste

Similar to Sensodyne and Colgate, Aquafresh contains a potassium nitrate agent to reduce sensitivity. Because it also contains a whitening agent, it doesn’t carry the ADA seal of approval. People also notice its effectiveness after using it for a few weeks.

How Potassium Nitrate Works

The theory is that potassium ions make the nerves inactive — they block the transmission of pain at the tooth pulp level. The best way to use toothpaste containing potassium nitrate is not to rinse right away after brushing. Let it stay in your mouth for about 30 minutes. It may take a few weeks of use before you notice a difference. Potassium nitrate has been used since the 1980s in toothpastes for sensitivity.

Nano-hydroxyapatite (Nano-HAp)

Nano-HAp is a relatively new agent that has been used in dental products to reduce tooth sensitivity. It works by occluding the exposed dental tubules. Studies show that it is highly effective. You can look for toothpastes and mouthwashes that contain this substance. Smilox is one brand name that contains Nano-Hap.
