Preparation
- Produced by neutralizing hydrofluoric acid with sodium hydroxide or sodium carbonate, followed by crystallization.
Uses
- Toothpaste and Mouthwashes: Strengthens tooth enamel, making it resistant to acid attacks and decay.
- Desensitizing: Forms a protective layer on teeth, blocking dentinal tubules and reducing sensitivity.
