In general, a crown may be recommended if:
-The tooth is severely damaged or weakened by decay or trauma
-The root canal treatment has left the tooth structurally compromised
-The tooth is in the front of the mouth and visible when smiling
-The patient grinds or clenches their teeth, which could put additional stress on the tooth
However, in some cases, a crown may not be necessary. For example, if the tooth is not severely damaged and is located in the back of the mouth, a filling may be sufficient to restore the tooth's function and appearance.
Ultimately, the decision of whether or not to place a crown after root canal treatment should be made in consultation with a dentist or endodontist.
