There are two type of tooth coloured restorations that are placed by dentists. One of these is COMPOSITE RESIN which is matched by the dentist to the remaining tooth structure. It is an advanced kind of plastic with glass filler particles, usually lasts about 5 to 7 years in a back tooth, but can chip, debond and stain with wear and tear. Resin is placed by the dentist straight on to the tooth, and set with a light and can be a good filling material when there is enough tooth structure to support it but if there is more tooth missing than present, it isn’t usually strong enough to hold up in the long term.
Porcelain is a natural looking option to restore teeth, that is not porous, and is much stronger than composite resin fillings. It is the most durable way to repair a damaged tooth with high aesthetic and functional demands. It is computer generated to match the defect in the tooth, without removing too much more tooth structure and is seamlessly bonded by your dentist. It is extremely durable, has excellent aesthetics and is very stable. It is made outside of the mouth with computer technology and hand finished and glazed by a master ceramist.. It takes two appointments to complete, where the first appointment is the preparation appointment, a temporary restoration is placed, and two weeks later the porcelain restoration is bonded into the cavity. They are bonded seamlessly to the remaining tooth by your dentist and look as good as the day they were placed many years later.
