A dental crown is a tooth-shaped “cap” that is placed over a tooth to cover the tooth to restore its shape and size, strength, and improve its appearance. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line. Today all ceramic or full porcelain crowns are favored as the most beautiful crown. They provide better a natural color match than any other crown type and may be more suitable for people with metal allergies.
A Porcelain Crown may be needed for any of the following reasons:
To protect a weak tooth suffering from decay, a crack, or break
To restore a broken tooth or one that has been severely worn down
To support a tooth with a large filling
To cover a dental implant
For cosmetic reasons
Preparing a tooth for a crown usually requires two visits to the dentist. The first step involves examining and preparing the tooth, the second visit involves placement of the permanent crown.
At the first visit in preparation for a crown, your dentist may take a few X-rays to check the roots of the tooth receiving the crown and surrounding bone. If the tooth has suffered a lot of decay or if there is a risk of infection or injury to the tooth’s pulp, a root canal treatment may first be performed. The tooth to be treated is cleaned, reshaped, and thus prepared for treatment. The tooth is filed so that the crown can snugly fit on top of the concerned tooth.
With the help of dental putty, an impression of the tooth is taken. The mold is then sent to the laboratory to make the new crown. In the meantime, the patient gets a temporary crown fitted on the tooth. A period of two to three weeks is required for the crown to be prepared.
At the second visit, your dentist will remove the temporary crown and check the fit and color of the permanent crown. If everything is acceptable, a local anesthetic will be used to numb the tooth and the new crown is permanently cemented in place.
Good oral hygiene and regularly scheduled are important for healthy teeth and gums. Hardy, sticky gum and candy should be avoided to increase the longevity of the crown.
