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