Fluoride and Tooth Decay

Tooth enamel is hard. It consists of many closely-packed rods made of minerals. When you eat, acid forms on the outside of the tooth and seeps into the enamel's rods. This demineralization process can produce a weak spot in the tooth's surface. If unchecked, the enamel can decay and create a cavity.

Fluoride helps prevent tooth decay by slowing the breakdown of enamel and speeding up the natural remineralization process. These microscopic views of the tooth's chewing surface show how fluoride works:

Healthy

Healthy tooth enamel rods before acid's onslaught.

Enamel rods demineralized, or broken down, by acid.

Demineralized
Remineralized

Enamel rods remineralized or rebuilt, by fluoride and the minerals in saliva.

Common sources of fluoride are fluoridated drinking water, toothpaste and mouth rinse. Inform Dr. Ortega if your drinking water is not fluoridated. High concentration fluoride gels, mouth rinses, drops and tablets may be recommended by Dr. Ortega.

Dr. Ortega may recommend at home fluoride treatments to reverse the decay process. If the weak spot is left unchecked, a cavity may form, necessitating a filling. If decay is allowed to spread, it may penetrate the root and enter the pulp (nerve) chamber, causing an abscess and requiring root canal treatment.

PROGRESSION OF TOOTH DECAY

Tooth decay often begins on biting surfaces, between the teeth, and on exposed roots.
 

Tooth decay
Untreated

Untreated, the cavity becomes larger.

Decay spreads beneath the enamel and can destroy the tooth structure.

Spreads
Enters pulp

Decay enters the pulp and an abscess may occur.

Use of fluoridated toothpaste can help prevent tooth decay at its early stage.

Be sure to follow the special home care instructions provided by Dr. Ortega.
