Veneers
are thin custom-made shells designed to cover
the front side of teeth. Made of tooth-colored
porcelain materials, veneers are used to treat
spaces between teeth and teeth that are chipped
or worn, permanently stained, poorly shaped,
slightly crooked or just to create a more
esthetic smile. There are essentially three
types of preparation for Veneers:
1. No Prep Veneers - Veneers
that are made with little or no removal of
tooth structure and are often prepared without
shots. Veneers of this type are usually reversible
(can be removed with little damage to the
original tooth structure) and provide the
least chance of sensitivity.
2.
Minimal Prep Veneers - Veneers
that are prepared with some contouring of
the tooth structure, and may or may not require
shots
3.
Full Preparation Veneers - Veneers
in which tooth structure is remove to provide
the optimal shape and size, and requires that
the patient is anesthetized
Often
Veneers are prepared using a combination of
the above preparation types. Preparation varies
from Minimum to Full Preparation depending
the existing tooth anatomy, alignment, and
the intended result. Cuttting more tooth structure
often allows the laboratory to produce Veneers
that are ideal and results in a more perfect
smile.
