Sodium fluoride is used in toothpaste and mouthwashes to strengthen enamel, protect against acid attacks, and reduce tooth sensitivity by blocking dentinal tubules.
Properties
Colorless, odorless, crystalline compound.
Highly soluble in water.
Has both desensitizing and anti-cavity properties.
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.
Storage
Store in a cool, dry place, away from moisture, heat, and direct sunlight.
Keep in a tightly closed container to prevent contamination.
Both calcium carbonate and sodium fluoride are effective in managing tooth sensitivity and improving overall oral health through different mechanisms.
