White or tooth-coloured fillings fulfill all of the important functions of regular fillings, but with the added cosmetic advantage of blending in with the rest of your teeth to keep your smile looking bright and natural.
About white fillings
The fillings are virtually indistinguishable from regular teeth and do not blacken over time. In addition to the aesthetic benefits, white fillings are also safer than traditional silver amalgam fillings. This is due to the materials used in each method. White fillings are made from composite resin, a reliable material also implemented in other cosmetic dental procedures, such as tooth bonding and certain dental bridges. White fillings are also durable and stronger than traditional fillings.
Why not silver fillings?
The silver amalgam fillings that have often been used have raised concerns in recent times. The mercury within the silver fillings does not damage the mouth immediately, but there is a small risk of mercury leakage over time, which can spread in small amounts throughout the body. At the moment there is wide debate over the effects this produces and the wisdom of using mercury in dentistry. Older fillings are especially likely to contain mercury. Talk to your dentist for information about the substances used in making your fillings.
Replacing old fillings
Many people from Bristol hear about tooth coloured-fillings for the first time when they need treatment for a new cavity, and this can prompt them to ask their dentist to remove and replace their old silver fillings. Doing so leads to a more symmetrical and attractive smile, untarnished by flecks of metal. The procedure is simple and can often be performed in conjunction with the placing of a new white filling. Broken or cracked fillings can also be replaced.
How long do white fillings last for?
White fillings are very durable, lasting on average between 6 and 12 years. As always this depends on your individual oral hygiene. People who keep their teeth and mouth healthy can make their fillings last even longer.
