Cavities/Tooth Decay

Tooth decay and cavities are one of the world’s most common problem.  It is softening of the tooth enamel which damages the structure of the tooth. It is caused by acids when plaque bacteria break down sugar in your mouth. If left untreated a cavity occurs due to the loss of minerals.

Tooth decay can happen to anyone from babies to elderly people. Bottle-fed babies are at a higher risk.
