Yes, it is very important to wear the crown on teeth that have root canal treatment because the teeth are weakened. However, with some exceptions, Crown is not absolutely necessary.
Crown crowns can be used to secure teeth and maintain their integrity after they have been destroyed, whether it is tooth decay or trauma. A tooth that must have a root canal already has a very large cavity that has reached the medullary cavity where the nerve is located. After the dentist has completely removed the teeth and completed the root canal treatment, there is usually not enough healthy dental material to fill the teeth. Then it is necessary to complete the treatment through the pillars and crowns to ensure that the teeth will not eventually break.
However, in some cases, the nerves of the teeth after the trauma are stimulated, not due to the destructive tooth cavity. If the traumatized tooth is not broken or broken, and if the tooth does not have a large filler, root canal treatment can be performed and the integrity of the tooth can be maintained. In this case, filling is sufficient to restore this tooth without the need for a crown.
