Traditionally, cavities (holes) in teeth were restored with a silver coloured filling material (amalgam). Over time, the seal between the filling and tooth can become lost. This can cause discolouration of the surrounding tooth and even decay underneath the filling. In addition to this, as the silver coloured filling material is very rigid compared to the relatively brittle tooth surrounding it, fracture lines can begin to form within the tooth structure. You may be unaware of this until part of the tooth breaks away or such issues are highlighted by your dentist.
Replacement of silver coloured or an existing and failing tooth coloured filling with a high grade composite restoration (white filling) can not only greatly improve the appearance of the tooth, but also reduce the possibility of problems occurring such as fractures, discolouration and decay
White fillings are made of composite resin (a combination of plastic and glass) that is placed in the area of the tooth to be filled once the existing filling or decay has been removed and the tooth cleaned. The material is carefully built up layer by layer, and then cured (set) with a blue light. This process is relatively quick, easy and can provide highly aesthetic results.
