Enamel defects (called enamel hypoplasia) are areas where the
crowns are not covered by protective enamel or have poorly formed
enamel. They commonly occur when a tooth is in a developing stage
early in puppy hood or kitten hood. Localized injuries can affect
enamel formation and occur commonly, for example, when a vigorous
6-week old pup jumps from someone’s arms and hits the floor. A deep
bruise can interfere with normal enamel formation. Also, any fever
producing illness can cause enamel defects in a number of teeth.
These defects are still commonly referred to as “distemper teeth”
because distemper is a fever-producing disease that was common
before modern vaccines were in widespread use. Regardless of the
cause, when enamel damaged, the remaining tooth structure
protecting the pulp is quite thin. This causes the teeth to be
sensitive. It also enables bacteria to enter the tooth’s pulp
chamber, resulting in death of the tooth. It is recommended that
these areas be cleaned and sealed to prevent bacteria from
entering. The areas can be restored with a bonded restoration as
pictured above. However, some energetic chewers will eventually
chip the restoration off. An older pet’s teeth with enamel
defects may or may not be healthy. They should be evaluated to
determine whether they are okay or need
therapy.
