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.
