Preventing Tooth Decay

What is tooth decay?
Tooth enamel is hard yet porous. Plaque on the surface of your teeth can produce acids that seep into the pores (rods) of the enamel and break down its internal structure. The process, is called demineralization, can create a weak spot on the surface of the tooth that may become a cavity if left untreated.

Decay often begins on biting surfaces, between the teeth, on exposed roots, and around existing fillings. Untreated, decay spreads into the tooth and can destroy the tooth structure. Decay enters and effects the pulp.

The role of fluoride:
Fluoride helps prevent tooth decay by slowing the breakdown of enamel and speeding up the remineralization process. The new enamel crystals that form are harder, larger and more resistant to acid.

Fluoride increases the rate of remineralization and protects against demineralization.

Treating and preventing tooth decay:
Common sources of fluoride are fluoridated drinking water, toothpaste, and mouth rinse. Inform your dentist if your drinking water is not fluoridated. He or she may recommend that you use high-concentration fluoride gels, mouth rinses, drops, or tablets.
