A filling is a way to restore a tooth damaged by decay back to its normal function and shape. If you have a tooth that requires filling, the dentist will first remove the decayed tooth material, clean the affected area, and then fill the cleaning out cavity with a filling material. A filling also helps prevent further decay by closing off any cracks or spaces where bacteria can enter.
There are two fillings available which include silver and also plastic. The dentist will work with you to determine which material is best for you, depending on the extent of repair, where in your mouth the filling is needed, and cost. Each of the filling materials is briefly explained below:
Amalgam (silver) fillings are a more inexpensive choice . However, due to their dark color they are more noticeable than composite restorations and are not recommended for fillings in very visible areas.
Composite (plastic) resins are custom made to the exact color of your natural teeth, creating a more natural appearance. Composite fillings also have the advantage of being able to actually bond your tooth together to help prevent fracture, which silver fillings do not. Because of the versatility of the composite resin, it is the filling material used in the majority of cases in today’s dentistry.
