Dental restorations


A dental restoration or dental filling is a dental restorative material used to restore the function, integrity and morphology of missing tooth structure. The structural loss typically results from caries or external trauma. Due to a cavity classification different materials are being used, for example :

- composites also called white fillings, usually light cured. A thin glue or bonding material is required. Composites are filled layer by layer and photo-polymerized each using light.

- glass ionomer cements are commonly used in dentistry as filling materials and luting cements. They bond chemically to dental hard tissues and release fluoride that may be beneficial for patients who are at high risk for decay.

- porcelain, ceramic or glass like fillings. They are usually used as inlays, onlays or crowns.

- another type of restoration is porcelain-fused-to-metal, which provides strength to a crown or bridge. These restorations are very strong and durable.

Sometimes a cavity can be very deep and close to the nerve. When this happens, the dentist will put a medicated temporary filling in the tooth for a while before putting in the permanent filling. This significantly reduces the chances of sensitivity especially to hot and cold.
