A Dental Crown is a tooth-shaped “cap” that is placed over a tooth to cover the tooth to restore its shape, size, strength, and improve its appearance. Dental porcelain (also known as dental ceramic) is a porcelain used by a dental technician to create biocompatible life like crowns, bridges, and veneers for the patient. Evidence suggests they are effective they are biocompatible, esthetic and insoluble. The crowns when cemented into place fully covers the entire visible portion of a tooth.
A dental crown may be needed for the following reasons :
- To protect a weak tooth from breaking or to hold together parts of a cracked tooth.
- To restore an already broken tooth or a tooth that has been severely worn down.
- Save a tooth that has been so damaged by decay that it can’t support a filling.
- To cover a dental implant. (implant crown)
- To cover and support a tooth with a large filling when there isn’t a lot of tooth left
Porcelain or all Ceramic dental crowns provide a more natural color match than any other crown type and may be more suitable for people with metal allergies. 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 permanently cementing of the permanent crown. At the first appointment we will anesthetize (numb) the tooth and the gum tissue around the tooth. Next, the tooth receiving the crown, is reshaped along the surface and sides to make room for the crown. After reshaping the tooth, an impression of the tooth and the opposing arch of teeth is taken. This is done to insure a correct bite. The impressions are then sent to a dental lab for the processing of the crown. The dentist or dental assistant will make a temporary crown to be worn while the permanent crown is being made. The temporary crown is placed using a weak cement so it makes it easy to remove when placing the permanent crown. During the temp crown stage, we advise that you avoid sticky, chewy foods which can pull off the temporary crown. Avoid chewing hard foods. Slide floss out-rather than lifting out when cleaning your teeth. Lifting the floss out, as you normally would, might pull the temporary crown off. We schedule out 14 business days for your second appointment. At this visit we will remove the temporary crown and check the fit and color of the permanent crown. If everything is acceptable the new dental crown is permanently cemented in place.
