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
