If you need one or more teeth filled, composite fillings are a popular alternative to amalgam fillings. Before you make your decision, you may want to talk to your dentist about any questions you have.
These are some of the more frequently asked questions about composite fillings.
Composite fillings are made from a tooth-colored resin consisting of a plastic mixture that has been reinforced with powdered glass material. Composite materials provide a more natural appearance than other types because the material can be matched to the color of the natural teeth.
The composite material used for treating cavities may also be used for dental bonding and for repairing cracked, chipped, or broken teeth. It can also be used to improve the appearance of an oddly shaped tooth or to close unwanted spaces between teeth for a more pleasing smile.
The exact time to complete the filling procedure varies depending on how large the cavity is and where it is located. Treatments using composite materials usually take about 10-20 minutes longer than amalgam.
The primary advantages of composite fillings are that the material bonds well, may prevent tooth sensitivity, and can be made to closely match the color of the patient's natural teeth.
If you consume food or drink that stains the teeth, such as coffee, tea, or red wine, after getting your treatment, the composite material may change colors. Your dentist can place a clear plastic coating over the filling to prevent this. Composite materials are not as durable as amalgam and may wear out and need to be replaced sooner. For this reason, some dentists recommend using other types of materials in the back teeth where there is more bite pressure and the filling is not as visible.
The dentist prepares the tooth and then applies the composite material in layers that are each hardened with a specialized light. Once all the layers have been applied and hardened, the dentist shapes the composite to fit the tooth and then polishes it.
It depends on your insurance plan. Composite materials usually cost more than amalgam. Some insurance plans may cover the cost up to the cost of an equivalent amalgam option and you will pay the rest.
If your composite fillings are worn due to teeth grinding or chewing, your dentist may be able to repair them.
