Dental Filling


Share it Please

A dental restoration or dental filling is a dental restorative material used to restore a tooth damaged by decay back to its normal function and shape. Usually the structural loose result from external trauma or caries, and sometimes it is lost internally during tooth preparation to improve the aesthetics or the physical integrity of the intended restorative material. The replacement of missing tooth/teeth structure is supported by dental implants which divided into two types: direct restorations and indirect restorations. A root canal filling is a restorative technique for filling the space where the dental pulp resides. Dentists by using an explorer, a metal instrument with a sharp tip, check for possible decay. Healthy tooth enamel is hard and can damage a healthy tooth so it should be usual with caution. For filling, dentist usually first removes the decayed tooth material, cleans the affected area and then fills the cleaned out cavity with a filling material. Gold, porcelain, a composite resin and an amalgam are som materials used for fillings. Based on the cost, any allergy or other conditions, you can choose materials for filling. Some types of filling materials cause sensitivity to air, pressure, sweet foods or cold. In some of these cases may take out the filling and put in a new one.
