The materials used to restore the missing tooth structure include nickel chrome alloys, resin composites (also known as white fillings), and silver amalgam. These are used as filling substances in the direct restorations. Indirect restoration means taking the tooth impressions, and fabricating the restoration externally.
The procedure for Dental Fillings
In the case of a toothache due to decay or caries, the dentist first identifies the affected area on one or more teeth. After being identified, isolation of the tooth is the first step in the filling. This is done in order to prevent the moisture from interfering with the process of bonding. After this the area is cleaned by removing the carries, the tooth is prepared for the filling process. The filling material is then put into the required area and then sealed with adhesive substance for bonding. Sometimes a special light is required to accelerate the bonding process. The composite restoration process is thus completed. It is natural looking as well as functional.
The composite materials are aesthetically better than the amalgam fillings. These filling can easily last for an average of 8 to 12 years. But this depends upon the individual oral hygiene supported with quality of dental products used.
The restoration by dental filling is safe, pain free and prevents the further dental decay and gives back strength and capacity to chew the various different foods.
