These are Dental Veneers which are fabricated in porcelain.
When the patient walks in for porcelain Veneers the dentist has to roughen/shape the poter surface of teeth after which a set of very precise Impressions/molds of the teeth are made and sent to the lab. The shade of the veneers is also decided by the dentistry in conjunction with the patient and sent to the lab. The patient is thus sent home with a set of temporary veneers on the outer surface of teeth if needed.
The lab creates a mock-up of the Veneers and sends it to the dentist who approves it and gives the lab the go ahead.
In the second appointment, the Venners are fixed on the surface of the teeth using special resins meant for the purpose. After affixing the laminates the excess resin is removed and the outer surface is polished for any resin residues.
