IV-AN AGEING SMILE
With time the natural function of the teeth causes the enamel to wear down. Grinding and clenching dramatically speeds this process up.
Prevention is usually best and your dentist may recommend that you wear a night guard if he finds your teeth to be abnormally worn down.
The more that your front teeth wear down, the more their length will appear identical. The central incisors should be slightly longer than the lateral incisors and the canines should appear more pointy. Constant wear will tend to flatten the contour of these teeth and result in a premature aged look.
If the teeth are already damaged by this wear and tear, porcelain veneers or crowns may be needed to restore the teeth to their original shape.
