When treating the cavity, the dentist will remove the decayed portion of your tooth and fill it with a tooth colored material called a composite.
The material used in the filling can be closely matched to the color of your teeth. Composite fillings provide good durability for small to medium cavities, and the procedure typically involves removing less tooth structure than you would during an amalgam filling. They are also particularly well suited for treating front or highly visible teeth because of their natural look.
How its done
After the dentist numbs the area where the filling is to be placed, he will remove any decay. A substance is then applied to help open up the pores of your teeth for a stronger bond, and hardened and cured with a special light. Once this is complete, the filling is applied in thin layers to slowly form the complete filling. After the composite has hardened, the filling will be smoothened and polished to be comfortable and fit your bite.
After you’ve had your tooth filled with composite, you may experience a temporary period of heightened hot and cold tooth sensitivity. Composite filling hardens instantly, so you can eat and drink immediately. Make sure to consult your dentist to understand which type of filling is right for you.
