  Dental Repair Procedures  
 
There are lots of reasons for undertaking dental procedures. It can be for maintenance, treatment of disease, or even for cosmetic reasons. Here we look at procedures used to repair teeth that have been damaged by disease and disorders.

Amalgam fillings

Dental filling is a restorative treatment used to repair tooth decay, minimal tooth fractures, and other damaged surfaces of the teeth. Dental filling may also be used to even out teeth surfaces for better bite. There are many filling materials available, of which are porcelain and silver amalgam, composite, and glass and resin ionomers.

Amalgams

Dental amalgams are tried and tested inexpensive restorative fillings that are used in dentistry for more than a century. Although its use is decreasing, it continues to be a valued choice for dentists since it is the most thoroughly researched and tested material.

Dental amalgams have been metal alloys made from mercury and metals like, platinum, gold, zinc and cadmium. Modern amalgams are made from mercury and alloys composed of silver, tin, copper and small amounts of Zinc, indium and palladium. Although concerns have been raised about safety of dental amalgams relating to its mercury content, major international scientific and health organizations have agreed that dental amalgams are safe, reliable, and are an effective restorative material.

Alloy components cause oral lesions in both patients and attending dental personnel, but only rarely. Amalgam removal can resolve the problem. Another disadvantage of amalgams is the tooth discoloration they cause. Also, patients may experience short-term hot or cold sensitivity after the filling is placed.

Composite fillings

Composite fillings, sometimes called composites or filled resins, make good a good alternative to amalgams since it is tooth-colored. They contain a mixture of glass or quarts, providing good durability and resistance to fracture. Composite fillings cost moderate depending on the size of the filling, and are also subject to discoloration over time.

Alternatives to amalgam fillings

Patients are now searching for aesthetically more acceptable fillings and refusing amalgam restorations. The latest fillings in use in the restoration of posterior teeth include resin-based composites, porcelain- fused- to- metal crowns (PFM), ionomers, cast gold alloy and all ceramic restorations. These fillings vary significantly in cost and longevity.
