Fillings are used to repair a small to medium sized cavities. Even though a filling is meant to stand the test of time, they can also be lost due to chips, fractures or the natural processes of bacteria in your mouth. In general, the older and larger a filling is more likely to be lost.
If the tooth lacks the sufficient amount of enamel left to anchor a new filling, Dr. John McAllister might recommend having the entire enamel layer of the tool restored with a crown made from an artificial material, like gold, base metal or porcelain.
During the initial appointment Dr. John McAllister will examine the tooth, to assess its overall health and extent of any existing decay. If damage or decay extends beyond the enamel layer, your dentist might need to perform a root canal to provide enough healthy structure to anchor a crown.
Dr. John McAllister will create an abutment by removing the majority of the enamel layer. This leaves behind a small amount to protect the interior of the tooth. Later on this abutment, will anchor your new crown.
Dr. John McAllister will them form an impression of the area. This will be sent to a dental lab, where your new crown is made. Then he will cement a temporary crown over the abutment to protect it while you wait for the dental lab to complete your permanent crown.
Dr. John McAllister will call you in for a brief follow up appointment when your permanent crown is back from the lab. The temporary crown is removed and your new permanent crown is cemented in place.
If you have a tooth that has recently lost a filling, you should call Dr. John McAllister at 828-322-6731 to schedule an appointment.
