Placing a dental filling involves replacing damaged tooth structure due to decay or fracture with a type of restorative material. Dental fillings help to restore form and function to the damaged tooth. Your dentist will discuss which restorative material is best for your specific tooth.
Composite resin restorations, are tooth-colored fillings and are a durable restorative material in most situations. They are tooth colored so they blend in well with surrounding tooth structure and can often be placed on both front or back teeth. In order to place a composite restoration tooth structure must be clean, dry and free of saliva. For this reason composite resin my not be the best option in certain areas of the mouth.
Silver amalgam restorations have been used in dentistry for over 100 years. They are a durable restorative material which are often used for larger restorations, especially on the back teeth, or areas below the gum line which are difficult to keep dry during placement.
