How Do Desensitizing Toothpastes Work?

The video discusses sensitive teeth and how desensitizing toothpastes work. It explains tooth anatomy, focusing on enamel, dentin, and pulp. Desensitizing toothpastes use chemicals like potassium nitrate and strontium chloride to block pain signals or tubules. However, these toothpastes only provide temporary relief and do not heal eroded enamel. The video concludes with a reminder to consult a dentist for persistent issues and thanks to Patreon supporters.
