The first thing that your dentist will do is to assess the situation to find out what has caused the crown to come off. If it is a result of tooth decay, the dentist will have to first treat the decay before installing a new crown or filling. That is because tooth decay deteriorates teeth, therefore, reducing their size.
The dentist will tell you how to take care of your fillings or crown to avoid getting them lost. Biting down on hard things with your crowned tooth is not recommended at all because of the known risks. However, some dentists forget to emphasize the importance of lost crowns or fillings to their clients.

You don’t have to panic if your crown or filling is lost. There is no need to call the emergency line as you can survive one night without your crown or filling. However, you should be ready to deal with the irritation that is caused as a result of exposure to the protected tooth. The pain is manageable unless in severe circumstances depending on the condition of the crowned tooth.
