Do I need a crown after a root canal?
Cadbury Dental team3 min readPublished Last updated
Back teeth almost always need a crown after root canal treatment, because they take heavy chewing forces and the tooth is more brittle once the pulp is removed. Front teeth with limited tooth loss can often be restored with a bonded filling instead.
Why protection matters
The most common reason a well-treated root-filled tooth is eventually lost is fracture, not reinfection. A crown holds the remaining tooth together and dramatically improves long-term survival.
- Molars and premolars: crown recommended in most cases.
- Front teeth with intact walls: often a bonded filling is enough.
- Heavily broken-down teeth: a core build-up first, then a crown.
Crowns, bridges & root canal: your questions on this topic
How soon after the root canal?
Usually within a few weeks, once we're satisfied the tooth is settled and comfortable.
What if I delay?
The risk of fracture rises with time. A fractured root-filled tooth often can't be saved.
Is the crown included in the root canal fee?
No — it's quoted separately, and you'll have both figures before starting.
