Crooked teeth

Straight teeth can not only improve your smile but are also easier to clean, so are less vulnerable to disease.

Treatment:

One way to overcome crooked teeth is with veneers, a thin porcelain shell, which is bonded to your own teeth.

A tooth shade is chosen and an impression taken of the teeth then a small amount of the tooth's surface is filed away.

Each tooth takes roughly ten minutes to file with no pain or discomfort.

Once the veneers have been made, they are bonded on with a special dental bonding material, which is extremely strong and can last up to 20 years.
