Dental fillings are the most common procedure that dentists perform. Dental filling are done with Gold, Amalgam, Composite, Ceramic and more. A filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and the fills the cleaned out cavity with a filling material.
By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, procelain, a composite resin( tooth-coloured fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).
Which Type of Filling is Best?
No one type of filling is best for everyone. What's right for you will be determined by the extent of the repair, whether you have allergies to certain materials, where in your mouth the filling is needed, and the cost. Considerations for different materials include:
Gold filling are made to in a laboratory and then cemented into place. Gold inlays are well tolerated by gum tissues, and may last more than 20 years. For these reasons, many authorities consider gold the best filling material. However, it is often expensive choice and requires multiple visits.
Amalgam (silver) fillings are resistant to wear and relatively inexpensive. However, due to their dark color, they are more noticeable than procelain or composite restorations and are not usually used in very visible areas, such as front teeth.
Composite (plastic) resins are matched to be the same colour as your teeth and therefore used where a natural appearance is desired. The ingredients are mixed and placed directly into the cavity, where they harden. Composites may not be the ideal material for large fillings as they may chip or wear over time. They can also become stained from coffee, tea or tobacco, and do not last as long as other types of fillings generally from three to 10 years.
Procelain fillings are called inlays or onlays and are produced to order in a lab and then bonded to the tooth. they can be matched to the tooth. they can be matched to the colour of the tooth and resist staining. A procelain restoration generally covers most of the tooth. their cost is similar to gold
If decay or a fracture has damaged a large portion of the tooth, a crown , or cap, may be recommended. Decay that has reached the nerve may be treated in two ways: through root canal therapy (in which damaged nerve is removed) or through a procedure called pulp capping (which attempts to keep the nerve alive).
