Since your tooth is now hollow on the inside and has a tiny hole in it, the next step is to restore the affected tooth. This is accomplished by first filling the inside of the tooth with a rubber-like material called gutta-percha. In some cases, one or more metal posts may also be placed inside the tooth as a way of providing additional support. A dental filling, usually made with composite resin, will then be used to seal the access hole. Then, a dental crown is generally adhered over the entire tooth to protect it from damage or future decay. Depending on the type of dental crown you are getting, your tooth will likely need to be prepared for the crown by being reduced slightly in size. This allows your permanent crown to fit more naturally and comfortably. After your tooth has been prepared, a dental impression or oral scan will be taken of your mouth and sent to a dental lab. A temporary crown will be placed until your permanent crown has been fabricated and can be cemented in place.
