Over time, the thin hard white substance covering your teeth (enamel) may become worn, dull and discolored. Such wear and discolouration 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.)
Teeth naturally wear down with age. Aged teeth are more likely to have chips, cracks or a generally uneven appearance.
Uneven teeth can result from tooth grinding or general wear & tear. Porcelain veneers create a very life-like tooth appearance and are resistant to staining. Porcelain veneers are a beautiful way to revamp stained, chipped and crooked teeth.
Wear and tear
Certain people may be born with abnormal spacing between the teeth that grows wider with age.
