Cosmetic Fillings & Inlays
White fillings and inlays are relatively new solutions to the problem of replacing holes caused by decay. They supersede amalgram (silver coloured and mercury containing) fillings, which have been used for around 150 years. Cosmetically, it makes more sense to use a tooth-coloured substance to fill holes, rather than unsightly amalgam which can spoil an otherwise attractive smile.
Method
White Fillings: Decay or old amalgam is removed, the holes are shaped and these are then filled with a tooth-coloured paste or composite containing glass particles. The composite is then cured with ultraviolet light.
Inlays: The best inlays are made from porcelain, providing a state-of-art way to fill holes left by decay. The decay is removed and an impression taken of the tooth which is used to create a plaster cast on which the inlay can be modelled. The result is an inlay which precisely fits the offending hole, modelled in detail to resemble a natural tooth.
