Root Canals

Crown necessary after root canal?



I am going to do a root canal on tooth #20, one of the back teeth.

The tooth has no damage from outside, just infection down below - is it necessary to do a crown on it after root canal???

I am worried it may weaken the tooth. I`m leaning towards just doing a permanent filling? But my dentist seem admant about doing a crown afterwards.


A similar question has been answered previously. The link below will connect you to that answer.

In relation to this particular question, tooth #20 that you are asking about is a premolar.  Also, sometimes if there is no visible damage to the tooth, there is a crack in the tooth that is creating problems.  With a cracked tooth, a crown is a must.
