Dental Did You Know: The Reason you Crown Posterior Teeth that have had a Root Canal.

From the Royal College of Dental Surgeons of Ontario's PEAK article program:

In a retrospective study of uncrowned endodontically treated teeth, the overall survival rates of molars without crowns at 1, 2, and 5 years were 96%, 88% and 36% respectively.

Yikes! So no matter how conservative the access for the root canal is and the lack of any significant caries, you should crown these teeth within two years and preferably one.
