Cavities in teeth happen because of decay or wearing away of teeth. The hard structure of
the tooth gets damaged leading to a hole on the tooth structure. They are very common
dental problems caused by food, poor teeth cleaning methods, excess sugar in diet and
excessive grinding of teeth.
Initially, they can cause tooth sensitivity, black discolouration on teeth, food lodgement
and when not treated, root infection and tooth pain.
For cavities involving enamel and dentin, fillings can be done with silver amalgam or
tooth coloured filling materials. When cavity is shallow but wide, complex fillings like
inlays and onlays can be considered. When tooth cavity is deep, root canal treatment is
the option advised.
