Using porcelain veneers to improve the symmetry of worn teeth.

For the most part, this virtual makeover case simply involves a smile that needs improved symmetry.

The upper teeth.

For whatever reason (we assume wear, see below), the upper left and right sides of this smile have a different look. That's not, however, what we expect to see when we look at someone. Instead, we expect the situation where both sides of the mouth are mirror images of each other.

The lower teeth.

Compounding this person's cosmetic issues are their lower teeth. When we look at a smile, we expect to see a smooth, symmetrical transition from the biting edge of one tooth to another. With this case, the worn edges of the lower teeth give them a slightly irregular appearance.

The solution.

Our digital makeover shows how the placement of restorations on the upper front teeth, and just a little tooth buffing and reshaping for the lowers, could go a long way in helping to give this smile a more uniform look.

Case issues and concerns:

a) Tooth alignment.

When you look at this person's bottom teeth, you can see that they're arranged at two different levels. A lower one that involves the right and left back teeth. And a slightly higher one involving the front ones.

Related to this configuration, this person has what is termed a "deep vertical overbite." This term simply means that when this person closes together, their upper and lower front teeth overlap significantly.

b) Tooth wear.

People who have a deep overbite frequently show signs of tooth wear. With this case:

• The curvature of the biting edges of the upper and lower teeth generally seem to mirror each other. This is typically a sign of tooth-against-tooth wear.
• The biting edges of several of the teeth appear chipped and irregular. This is often due to the fact that as enamel wears thin it chips easily.
