Dental filling is a procedure used to fill a hole or cavity in a tooth. Fillings are applied in case of dental caries or in tooth lost due to trauma. Filling is the process of restoring decayed, broken or worn teeth. The aesthetic appearance of today’s fillers is quite good and can be applied in a single session.
Filling types used today are amalgam fillings, composite fillings and porcelain fillings.
Amalgam fillings consist of a mixture of mercury, silver, tin and copper. Amalgam fillings, which are especially used in posterior teeth, are extremely resistant to pressure and chewing. However, its use has been declining in recent years.
Composite fillings consist of a plastic mixture with silicon dioxide particles. It is frequently used in posterior and anterior teeth due to its robustness in terms of both aesthetics and durability. It is a costlier type of filling than amalgam fillings.
Porcelain fillings are the most compatible filling material with teeth among all filling materials. There is no loss of texture in porcelain fillings and they are extremely durable fillings. They are primarily preferred in teeth where substance loss is intense.
