Oral Disease

Plaque

Plaque is the sticky film

of bacteria that coat

your teeth

These bacteria secrete

acids as a waste

product that can

dissolve enamel

Cavities

Formed when the

enamel is dissolved

by the acid from the

bacteria

– These bacteria

live on sugars

Cavities Cavities must be

drilled first and then filled.

The deeper they penetrate into the tooth, the more difficult the repair.

Plaque Plaque left in place

long enough forms tartar

Tartar provides a permanent home for harmful bacteria

Periodontal disease

Plaque accumulates

forming tartar

A build up of tartar

can lead to disease

of the teeth or gums:

periodontal disease
