Porcelain Dental Crowns in Sunnyvale
Durable and natural-looking crowns
A crown is a cap that completely covers a tooth. Crowns are generally made out of porcelain or some other type of ceramic. In some cases a porcelain crown will be fused to a strong shell of metal, such as gold for greatest longevity, or a hard ceramic.
Dr. Au has a lot of experience placing crowns as well as considerable training in aesthetic dentistry. He will choose a shade and shape of crown that will best match your other teeth. For your crown fabrication, we use an excellent lab that uses the best materials and creates very natural-looking restorations. While our quality is excellent, you will find our prices for crowns very competitive.
New porcelain crowns are made in two appointments, in the first, Dr. Au takes impressions, prepares your tooth for the crown and places a temporary crown. In the second appointment your permanent crown is cemented on.
Single Crown (Impression)
Patients have the option of all-ceramic crowns, meaning they have no metal in the core. For the hard-biting teeth in the back, Dr. Au uses crowns made out of a block of zirconia, the hardest known ceramic. For crowns on the front teeth, he layers the zirconia with aesthetic porcelain that gives the same translucent look of natural teeth.
Uses of Crowns
Porcelain crowns are employed for a variety of purposes, the most common being to take care of a very large cavity that threatens the health of the tooth.
Other reasons crowns are used include:
- To protect a tooth that has had a root canal. Teeth are more susceptible to fracture as a result of root canal therapy, as the dead tooth is now less resilient.
- Missing teeth can be replaced with dental implants, in which case for single-tooth replacements, a crown is attached to the implant.
- Crowns can be used for aesthetic purposes to improve the color, shape or style of a smile. Usually veneers are employed for this purpose, but in some cases a patient needs full coverage, such as when there is too much decay, the tooth has a fracture or the patient grinds down on his or her teeth.
- Crowns can also be used to correct a poor bite (how the teeth come together).
