When repairing a small cavity a dental amalgam filling (also known as a "silver" filling) can restore your tooth to shape and function in a cost effective manner.

Dental amalgam is made of a mixture of metals and is usually used to repair cavities in the back of the mouth. It is very durable and has been used by dentists for many years.

During the first step, your tooth is prepared by removing the decayed portion, leaving a small area that will be filled with the amalgam.

Your dentist then applies the amalgam to the prepared area, presses it into place, and shapes it to match the contours of your tooth.

As a final step, the amalgam is then polished to create a smooth finish.

Once completed, your tooth is free of decay and restored to its natural strength and durability.
