They are used to treat a decayed tooth where the cavity has not touched the blood and nerve chamber of the tooth.

They can be white tooth colored fillings or silver fillings.

Sometimes decay can happen on areas of teeth next to the gums from cheek side or tongue side and these cavities can make your teeth very sensitive and expose the nerve faster. These are called Cervical cavities or Cervical Caries and happen mostly due to receding gum line and exposure of the root of the teeth.

Filling is needed on these surfaces of the teeth to treat decay and changing Oral hygiene habits can make a significant contribution to them.

Use of a  soft bristled tooth brush with correct brushing habit is recommended.

Oral Hygiene Instructions are absolutely necessary to maintain healthy teeth in the mouth.
