Porcelain dental crowns replace the exterior portion of a tooth to re–establish its original function and to create a natural appearance. Crowns are the treatment of choice in situations where tooth decay has destroyed most of the original tooth, when a traumatic event has caused damage, or in cases of severe enamel erosion. They are also an option for people who grind and clench their teeth so much that the original structure of their teeth has been compromised.
The great benefit to porcelain crowns is they can not only replicate the original tooth in function, but can be designed to look like the original or even better. When patients select a porcelain veneer for cosmetic reasons, they’re usually covering up the front portion of the tooth that has some aesthetic flaw. A porcelain crown is thicker than a veneer and, in some situations, this thickness is needed. A porcelain crown can be used for cosmetic reasons, but it’s best to seek the advice of an AACD member dentist.
Crowns and veneers are situated and secured in the mouth in a similar fashion, using a light-sensitive resin placed between the original tooth and crown, and then hardening that resin with a special curing light.
Partial crowns, often referred to as onlays, are a type of restoration or filling that covers one or more cusps. An inlay is similar to a filling but the work resides completely within the cusps on a tooth’s chewing surface. These restorations are much more conservative than crowns, and can be imperceptible from your natural tooth.
POTENTIAL CROWN DOWNSIDES
Porcelain dental crowns do require some laboratory time to be created and times vary according to the laboratory and its distance from your dentist, so expect to be fitted with a temporary, or provisional, crown for a while.
Some patients may experience sensitivity to hot and cold temperatures after porcelain crowns are attached. It’s best to consult with your dentist for more information about your individual case.
While porcelain crowns are very durable, they do not have the flexibility of natural teeth, so avoiding certain foods may be necessary. Chronic tooth grinders and jaw clenchers will need to be fitted with a nighttime mouth guard to protect the porcelain from unnecessary and excessive pressure and use.
MAINTENANCE OF A CROWN
Maintaining porcelain dental crowns is actually quite simple. Much like your original teeth, they require routine brushing with non-abrasive fluoride toothpaste and regular flossing.
A follow-up appointment will be scheduled to evaluate the crowns shortly after they’re placed, so the dentist can review the work and see how your mouth is reacting to the crowns. Even if you think the crowns are successful, this follow-up appointment is an important part of your future oral health.
