Dental amalgam is a dental filling material used to fill cavities caused by tooth decay. It has been used for more than 150 years in hundreds of millions of patients.
Dental amalgam is a mixture of metals, consisting of liquid mercury and a powdered alloy composed of silver, tin, and copper. Approximately 50% of dental amalgam is elemental mercury by weight.
Dental amalgam fillings are also known as “silver fillings” because of their silver-like appearance.
Natural, tooth-colored composite fillings are less obvious than older silver amalgam fillings. Sometimes fillings need to be replaced, and many people choose to replace their fillings with composites when it is necessary to replace older fillings. Composite fillings wear well in small cavities but tend to wear out sooner than silver fillings in large cavities.
Gold fillings, also called inlays or onlays, are composed of an alloy of gold, copper and other metals.
This type of dental filling is usually considered the most durable, lasting 20 years or more, but it is also the most costly. Gold fillings also require more than one office visit to place because they require impressions to manufacture at a dental laboratory.
Root Canal Treatment
Endodontic therapy or root canal therapy, is a sequence of treatment that involves the removal of the pulp tissue (which consist of nerve tissue, blood vessels and other cellular elements) from its chamber and the root canals and the subsequent shaping, cleaning, and decontamination of the hollows with tiny files and irrigating solutions and the filling of the decontaminated canals with an inert filling such as gutta-percha and typically a eugenol-based cement.
- In the situation that a tooth is considered so threatened (because of decay, cracking, etc.) that future infection is considered likely or inevitable.
- Darkening of the tooth when the patient meets with an accident/ trauma to anterior tooth
- A long standing dental infection in the bone that erodes through the side of the bone and causes sudden, serious and painful swelling.
- In case of severely worn out teeth, where crown is the required treatment. Before placing a crown in such a case, that tooth may need to be Root Canal Treatment.
After endodontic surgery the tooth will be “dead”, and if an infection is spread at the apex, root end surgery is required, therefore it is very important to have regular X-rays taken of the root canal to ensure that the tooth is not having any problems that the patient is not aware of. However, if no infection at the apex, with the removal of nerves and blood supply from the tooth, (which is now brittle) it is best that the tooth be fitted (protected) with a crown that covers the cusps of the tooth otherwise, over the years, the tooth almost certainly fractures.
