Porcelain Crowns
A porcelain crown is a permanent restoration designed to cover structurally compromised teeth. Small fractures, cavities and stains can be successfully repaired with regular resin fillings. Crowns are used when more modest methods of restoration are not sufficient to regain the lost aesthetics and functionality of the dentition.
Why Choose a Crown
A crown is one of the most effective methods of dental treatment to save the existing teeth. It is a permanent solution and is often chosen by patients who do not feel comfortable wearing removable prosthetics such as partial dentures. Ultimately, crowns closely mimic the appearance of natural teeth, protect the remaining tooth structure and provide exceptional aesthetics. They also retain a correct occlusal plane allowing the patient to function in their usual routine manner. Other reasons why the crowns are a good choice include the following:
- Protect teeth weakened due to fractures, extensive decay or root canal treatment (RCT)
- Restore teeth that have been worn down because of grinding (bruxism)
- Support teeth with large fillings
- Cover the implants
- Cosmetic modifications for severe staining or misalignment
The Treatment
The process begins with an evaluation of any present conditions. Once it is determined that the patient is a good candidate to receive a crown, a prophylactic cleaning is performed by a hygienist to establish a positive oral flora. At the following appointment the tooth structure is reduced and prepared for a crown placement. The shape and the hue of the porcelain are chosen at that time to ensure patient’s satisfaction. Before the patient receives a permanent crown, a temporary restoration is placed to prevent any sensitivity and the adjacent teeth from migrating into the empty space.
The next appointment consists of crown delivery when the temporary crown is replaced with a permanent porcelain crown that replicates natural tooth and provides proper oral environment for the gingiva to form naturally around the new restoration. The dentist also ensures that the speech patterns, mastication and occlusal vertical dimensions are appropriately addressed. The porcelain crown is then cemented onto the prepared tooth matching, and often improving, the existing smile line.
Post-Care
Life expectancy for a crown is estimated to be on average of 20 years. With proper care at home, many crowns may last a lifetime. It is important to remember that although the crown protects the tooth structure, it does not completely eliminate the tooth’s vulnerability to decay and gum disease. Habitual home care regimen should be implemented as with any naturally existing dentition.
