If you happen to be diagnosed with a cavity in one or more teeth, a dentist will often use a filling to prevent any further damage.

Fillings can be comprised of materials such as amalgam (silver), plastic and porcelain. Let us take a look at three important takeaway points:
-  Larger areas of damage may require a crown or a cap.
-  It is possible to select a filling which matches the colour of your tooth.
-  Ignoring a cavity can lead to further dental complications, including root canal treatment.

A filling protects the tooth from further decay.

"A filling is a way to restore a tooth damaged by decay back to its normal function and shape."
