In dentistry, a veneer is a thin layer of restorative material placed over a tooth surface, either to improve the aesthetics of a tooth, or to protect a damaged tooth surface. Dental veneers are custom-designed shells of tooth-like ceramic material that, when applied over the surface of a tooth, can cover worn tooth enamel, uneven tooth alignment or spacing, and chips or cracks. Worn enamel: Over time, the thin, hard white substance covering your teeth (enamel) may become worn, dulled, and discoloured. Such wear and discoloration may be natural or the result of a genetic predisposition; however, it is often a result of your habits (soft drinks, tea or coffee consumption, smoking, medication use, etc.). Wear and tear: Teeth naturally wear down as people age. Aged teeth are more likely to have chips, cracks or a generally uneven appearance. Crooked or Misaligned teeth: Certain people may be born with abnormal spacing between the teeth that grows wider as they age. Uneven teeth: Uneven teeth can result from tooth grinding or general wear and tear. Regardless of what causes unattractive teeth, dental veneers may solve most or even all of your cosmetic dental issues.
