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. This process, called demineralization, can create a weak spot on the surface of the tooth that may become a cavity if left untreated.

beginning tooth decay untreated tooth decay
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.
infected tooth pulp
Decay enters and infects the pulp.

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.

plaque fluoride protection

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.

To help strengthen weak spots and exposed roots and prevent the early stages of tooth decay, brush regularly with a fluoridated toothpaste like Crest® Cavity Protection. In one study, patients using Crest Cavity Protection developed 41% fewer cavities than patients using a toothpaste without fluoride.*
