It is common for some fillings to fall out when they have become old. Once this happens, pain can be felt due to exposed tissue, but the pain is not generally severe. The tooth may also become chipped once the filling is gone. The first thing the dentist will do is to clean any decay that may be built up between the tooth and the old filling, once this is done, they will start the process of placing a dental crown over the tooth. If you are having this problem and have never had this done before, it is likely confusing to you. If so, keep reading so you will know what is going to happen when you sit in the dentist's chair.
Dental Crown Mold
The dentist will need to do a mold to make a dental crown. First, they will make an impression of both your lower and upper jaw. This is to help the dental lab to create a drown that will fit when you bite down. The mold will be sent to a dental laboratory to have the crown made.
The dentist will also make a smaller impression of your tooth to create a temporary crown. This is generally done in the dentist office. The temporary crown is worn until the dentist can put on the permanent crown. It is important that you be careful with the temporary crown, such as not chewing on that side, because it can fall off. If this happens, you will have to go back to the dentist to have the crown secured again.
Permanent Dental Crown
When the permanent dental crown arrives, the dentist will remove the temporary crown and then place the new crown over your tooth. When it is in place the dentist will ask you to bite down. This is to see if your teeth meet each other instead of the teeth first meeting with the crown. If the crown is too large, the dentist will have to use a special type of file to file it down until you have the right bite.
This may take time because they will file a little bit at a time until the dental crown fits your tooth perfectly. The entire process of installing a permanent crown may take approximately one or less hours. You will receive an anesthetic injection before the crown is placed in most cases.
