When a tooth must be restored or a person simply wants a better smile, he or she can go to a cosmetic dentist and have a resin crown made that will cover the tooth. A resin crown is made from a special mixture of microscopic particles and cosmetic dental resin. The particles resemble tiny pieces of glass mixed into the resin, which is then cured to harden and strengthen the compound.
A model of the tooth is used to make the resin crown. The resin compound is molded around this tooth and then hardened with a curing light. This is done by experts in a dental lab. Later, when it is ready, the crown will be bonded to the tooth that needs restoration. In the meantime, however, certain preparations must be made to make the tooth ready for the crown.
It normally takes two visits to prepare for and receive a resin crown.
During the first visit to the office, the cosmetic dentist begins by numbing the gum tissue beneath the tooth in order to free the patient from any possible discomfort or pain. After that, the dentist takes additional precautions against the possibility that of pieces of dental debris falling into your throat.
This is averted by means of a device known as a rubber dam. The rubber dam is placed in the back of the mouth and effectively shields the airway and esophagus from dental debris.
The next step is to start working on the tooth itself. The dentist checks for decay and identifies the nature and degree of damage it has done to the tooth. He or she then removes it with a dental handpiece and reshapes the tooth so the resin crown will better fit over its surface when it is mounted.
The resin crown is not made by the cosmetic dentist. Instead, it is made by a dental laboratory that has never seen nor will ever see your actual teeth. To show them what the dentist sees, the dentist takes an impression of the teeth and uses it to build a model. Then, the dentist sends this model to the lab, which in turn uses it to create the dental crown.
To protect this vulnerable tooth from the possibility of decay, damage, and alignment problems, the dentist protects it with a temporary crown before sending the patient home. It usually takes a week or two for the lab to make the permanent crown and send it back to the Cosmetic Dentistry Centers.
When it arrives, the patient is called back to the office the second appointment. The dentist removes the temporary crown and mounts the permanent one in its place. Initially, the crown is not cemented to the tooth. The dentist needs to see if it fits correctly, lines up evenly with other teeth, and measures at exactly the same height as existing teeth.
Once the resin crown has passed all of these tests, it is then bonded to the tooth. The patient can expect this new crown to offer a number of key benefits during the years to come.
-It is made from material that expands and contracts like natural tooth structures.
-During chewing, it is easier than other materials on opposing teeth.
-It appears natural because it can be made to imitate the color of natural teeth.
