If you have tooth decay, then you will need to have a filling. The area must be prepared prior to a filling, by removing all the decay and shaping the cavity to hold the filling in place. If the decay is more extensive, your dentist may need to place an inlay or only (partial crown).
Amalgam fillings are silver coloured, they are made by combining mercury and a silver alloy (composed of 50% Mercury, 35% Silver, 15% Tin and other metals). Silver Amalgam fillings are long lasting, hard wearing.They are normally used on the back 'chewing' teeth or if a tooth contains a lot of cavity.
White Fillings, which are also known as composite resins, allow teeth to be filled using more aesthetically pleasing materials, giving a much improved appearance. White Fillings do not contain mercury and are an ideal choice for achieving long term aesthetic aesthetic results.
White fillings have always been considered less durable than silver amalgam fillings. But new materials are available comparable to silver amalgam. The life expectancy of a white filling can depend greatly on where it is in your mouth and how heavily your teeth come together when you bite.
If you have excessive pain in your mouth or tooth, you may need a root canal. A root canal is necessary when a large tooth cavity reaches the nerves within a tooth and becomes infected.
Root canal pain can be unbearable. By removing bacteria and damaged or dead nerves, the tooth can be sealed and the tooth infection can begin to heal, allowing the tooth to be restored back to full health.
