Replacing and Polishing Anterior Composite Fillings

Composites are the best method available to date to fill up dental cavities — especially situations which demands for superior aesthetics.

 

Composite restorations may last for a very long time, but as time passes, the microstructure of the surface may suffer the inevitable wear and tear damage. The altered irregular surface may pick up stains, causing the (originally) aesthetic filling to discolour. Depending on the severity, the discolouration of composites can be removed by either polishing; or some times, complete replacement of the restoration.

 

In the following example, both upper central incisors were filled with composites sometime ago. Discolouration of the upper right (your left) tooth is more obvious in comparison to the one on the left (your right). Some leakage is also noted around the margins of the filling next to the gums.  To prevent further propagation of dental caries underneath the filling, the previous composite filling was removed carefully, and then restored.

 

The upper left tooth with mild discolouration and surface irregularity was corrected with simple trimming and polishing.
