Tooth Coloured Fillings Treatment invisibly repair as well as protect damaged teeth by replacing the ugly metallic fillings. These dental fillings mimic the look, feel and function of natural teeth. It comprises of two parts, enamel and the dextrins. The external enamel is imitated by dental porcelains while the inner dextrins is composed of plastic resin and silica filler. Metallic fillings or amalgams could not bond with the tooth and they merely rested on it and provided a degree of protection. Dental restoration recreates a tooth which looks natural and responds naturally by, allowing bite stress to pass through the tooth while receiving biting force. Direct fillings require small amounts of restorative materials being placed into cavities resulting from decay. The resin is applied in layers which are instantly set with special lights, meaning the entire filling can be built up and repaired by the time one leave the office. Semi-Direct fillings use Computer Assisted Design / Computer Assisted Milling to create the inlays. This technology allows dentist to make a harder, more durable porcelain restoration without having to send out a mould to a remote fabrication facility. Indirect fillings are used when a very large or complex restoration is required When there is not enough healthy tooth left to fill, a dental restoration is created to replace most of the visible tooth, or to crown it. These are more involved procedures and cannot be made directly to the tooth and cannot be placed the same day.
