If you are concerned with a stained, crooked, chipped and/or gaps in between teeth, then these conditions can be corrected by cosmetic bonding. In most cases, this procedure can be done in a single appointment, in which layers of tooth-coloured composite resin are bonded to teeth to correct the defects and also cover the internal stains in teeth. These will eventually stain in a few years and will need to be replaced. As the material is composite resin, the restoration can break or fracture as well, it will need to be replaced when that happens. A more stable, aesthetic and long lasting solution will be to place ceramic veneers on those teeth.
