The Cosmetic Wonder of Porcelain Crowns
Porcelain crowns have been a staple in cosmetic dentistry for years. It gives the dentist and patient a much more aesthetic appearance as a final product. In the past crowns and bridges were traditionally made of porcelain fused to metal (PFM). With the development of modern porcelain, which are incredibly strong and reflect light similar to natural teeth, full porcelain crowns can be used in most areas in which porcelain fused to metal crowns were used. This is especially true in a cosmetic area of the mouth.
Porcelain crowns are very versatile and used in many ways. The cosmetic enhancement use of porcelain crowns include, changing color of teeth, closing gaps between teeth, fixing teeth that are crooked or crowded, changing shape or size of teeth. Porcelain crowns are also used to cover and protect damaged teeth, (tooth that has a root canal, broken, cracked, large fillings), and to act as a new tooth in the case of dental implants. Their versatility gives the dentist a greater flexibility in using them to fix potential issues for the patient.
The first step often times includes impressions for study models and photos. The patient and dentist can then discuss and plan what the end result should be. The treatment includes preparation of the tooth surface for the porcelain crowns. The outer enamel and sometimes a bit of the dentin are removed. This allows room for the porcelain crowns to fit over the teeth and be in perfect cosmetic alignment with the others. Impressions are taken of the newly reshaped teeth and temporary crowns are made. The porcelain crowns are custom made in the laboratory. The porcelain crowns are then cemented or bonded onto the teeth using an adhesive bonding material. The placement of the porcelain crown will normally take about 30 minutes (depends on amount of porcelain crowns being placed). Once completed, the patient can eat normally and enjoy the benefits of a beautiful new porcelain crown that matches and blends perfectly with the patients existing teeth. Only you and the dentist should know anything was done.
