Tooth decay happens to many of us.  Whether it is due to poor dental care, diet, fluoride deficiency, or another factor, tooth decay is a painful, bothersome problem. 

Tooth decay, most often called cavities or caries, occurs due to a build up of bacteria in the mouth, which becomes dental plaque.  When sugary or starchy foods are eaten, the bacteria produce acids, and plaque traps these acids against the tooth enamel.  The acids then attack the enamel and dissolve the enamel surface, creating a hole. 

Since tooth decay is so common, most treatments are non-invasive.  If the decay is just beginning, a fluoride treatment of a liquid solution, gel, or foam can help the tooth repair itself.  If the decay has created a hole, a filling is usually necessary.  The buildup is removed and the hole is sealed with a material such as silver alloy, gold, or porcelain. 

A dental crown may be needed if the decay is more severe.  The decay is drilled away and a crown made of metal/and or porcelain is used to cap the tooth.  In extreme cases, a root canal or tooth extraction may be necessary.  Your dentist can determine the type of treatment you need if you suffer from tooth decay.
