Composite resin is a modern restorative material that is used to fill teeth where the cavity or space to be restored is small to medium. While there are multiple options for the material used in the filling procedure, most common and effective is composite resin. Composite resin has the advantage of being tooth coloured or “white” so that it matches the tooth perfectly.
With composite resin, less tooth structure needs to be removed in the preparation, as compared with amalgam fillings. This then allows more surface area to bond the filling to as well as providing a stronger overall tooth. Composite resin comes in many shades and colours that can be matched to the colour of your original teeth, allowing composite fillings to be used on your front or highly visible teeth.
The length of time needed depends on the size of the restoration. There are several steps in the procedure. First, the teeth are anaesthetised to prevent any pain or sensitivity, then the decayed portion of the tooth is cleaned. Next the tooth is prepared for bonding of the filling to the tooth. The adhesive is applied and hardened under a special light. The filling is then applied in thin layers to make sure that they are all hardened sufficiently. The final step to this procedure is to adjust and polish the filling so that it fits your bite and to make sure that you are comfortable.
Rubber dam is used wherever possible. Rubber dam is used to isolate the teeth from the rest of the mouth. It helps to keep the teeth dry when bonding composite resin and helps retract the tongue and lips. It will also help to prevent debris from falling into the mouth making the whole experience more comfortable for patients.
