Can you explain the tooth preparation process for veneers?
Your comment has been received. Thank you.
Preparation is the next phase after the treatment plan design which is dedicated to preparing and taking an impression of the teeth. The procedure usually takes between 1.5 2 hours. Although porcelain veneers are very thin, in most of the cases the depth of the tooth has to be adjusted to allow for the small added thickness of the veneer. The procedure involves removing only a thin amount of the enamel which is the outer layer of the tooth. The tooth surfaces that have to be reduced are the front face and the top of the tooth. The amount of enamel that has to be removed is usually nearly equal to the thickness of the veneerto be added to the tooth surface between 0.5mm to 1.0mm, but it can be up to 2.0mm. It depends on how drastic is the change on the shape or size of the tooth. This procedure of tooth reduction is called ‘prepping’. In some cases, no enamel has to be removed. Next, after the tooth or teeth are prepared, your dentist will take an impression of the teeth and make a mold. This model is sent to a dental laboratory, which will fabricate the porcelain shells (veneers). It take a 221 days for the lab to return the veneers to the dentist. If the veneers are going to be made in a dental lab, it may be needed that you are fitted with temporary veneers for some days while your permanent ones are fabricated. Temporary veneers may be necessary if teeth have undergone extensive preparation and they have become unsightly or sensitive to hot and cold due to enamel loss. Even if not needed for these reasons, temporary veneers may be beneficial for the final result of the treatment, as they can give you a preview of the expected outcome. Based on how the temporary veneers look in your mouth you can ask your cosmetic dentist to make any adjustments or changes in shape or size you would like to the final model before the development of the permanent tooth veneer. Temporary dental veneers have an additional cost, so the dentist will not always use them.
