Getting a dental veneer usually requires three to four visits to the dentist
First visit for consultation. During this appointment, your dentist will examine your teeth to make sure dental veneers are right for you and discuss your expectations, the procedure and some of its limits. They will take X-rays, photos and scan your teeth to make digital impressions of your mouth and teeth to design the treatment plan and prepare the digital wax up. So on the next visit they will have ready the silicon keys to fabricate the mock up before the preparation of the teeth and the temporaries after.
Second visit to prepare the teeth. Veneers is less invasive method than the crowns. The dentist must remove only 0,3 to 0,6mm amount nearly equal to the thickness of the veneer to be added to the outer surface of the tooth. A local anaesthetic may be used to make sure there is no discomfort. A scan is taken and send to the lab. Forget the old silicon impressions they caused vomiting and nausea. One to two weeks later the lab will sent the venners. Temporary dental veneers are used in the meantime.
Third Visit. In this appointment the dentist will make a try-in of the venners. This is necessary to evaluate the fit,shape ,size, colour and make any changes if needed.
Final appointment to bond the veneers.
On this appointment your dentist will prepare the teeth to receive the veneer. Your teeth will be cleaned, polished, and etched. Etching roughens the tooth to allow a strong bonding process. A special cement is applied to the veneer and it is then placed on your tooth. The veneer color can be adjusted with the shade of cement to be used. Once the veneer is properly positioned, your dentist will shine a special light beam on it to activate the cement, causing it to harden very quickly. The final steps involve removing any excess cement, checking the occlusion and making any needed adjustments. You may have to return for a follow-up visit in a couple of weeks to check your gums and the veneer's placement.
