For all our best efforts to keep our teeth healthy in Gloucester, sometimes problems get through. Tooth decay starts with the build up bacteria, leading to plaque, gum disease and ultimately tooth decay. Often, tooth decay or caries are a result of poor oral hygiene and lack of dental visits over a period of time and getting treatment can be expensive. If the decay is in it’s early stages, the best course of action may be a flouride varnish or paste. Flouride with strengthen the enamel in the tooth and make it resistant to the causes of decay. If however, the decay is in a more advanced state, the tooth may require a filling, a root canal or a crown. A filling is used where the decay has not penetrated deep in to tooth, and can be made from various materials, the most common being a silver amalgam, but the more popular being a tooth coloured composite. Gold inlays and onlays can also be used to fill the cavity. If the decay is very bad, it may require a root canal to remove the dead nerves and pulp inside the tooth, then the tooth can be filled or have a crown fitted. Crowns too come in various colours and materials. But sometimes, the dentist will have no choice but to extract the tooth. Once this has been done, replacement can be expensive, in the form of a bridge or an implant.
