Veneers last for a long time and moreover they require very little tooth preparation. They look very natural and healthy.
For a strong bond between the teeth and the veneer the enamel has to be reduced. The dentist reduces the enamel and takes the impression of the teeth, and then it is sent to the lab where the veneer is made. The thickness of the veneer is same as the amount of veneer reduced. Hence the veneer looks very natural, as its color is made identical to the surrounding teeth.
Patient does not experience any pain, but there is some amount of discomfort when the enamel is reduced .The dentist gives an anesthesia before filing and reshaping the teeth, but there is no pain when the veneer is attached. Sensitivity to cold/ hot can be felt after the veneer is fitted.
