Compared to filings which just cover a small portion of a tooth, a crown (or cap) encases the entire visible portion of a tooth. In effect, the crown acts as the tooth’s new outer surface. A dental crown is used when a tooth is broken or decayed to such an extent that fillings aren’t able to repair the problem. The crown is able to provide a protective shell around the damaged or decayed tooth to strengthen it, as well as to improve the appearance of the tooth. While crowns come in different materials, Dr. Tharp uses a zirconia material which is all porcelain and no metal.
How it’s done
The first visit involves reshaping the tooth and taking impressions to create the crown. After Dr. Tharp reshapes your tooth, he will use a special material to create an impression of it. This impression will be sent to a dental laboratory to be made into a permanent crown. Before sending you home, he will provide you with a temporary crown to cover your tooth in between visits.
When you return, he will have received the permanent crown from the laboratory. Dr. Tharp will remove the temporary crown and fit the new permanent one. Before cementing, he will ensure that it fits comfortably and matches the color of your teeth.
