How are the back teeth different from the front teeth when you have a root canal done?
16 years ago I had a root canal done to a canine tooth and also one done to premolar tooth. For both of them I had put on a permanent filling. The canine survived for 15 years but changed the color to yellow-black ( I put a crown on it because of the color) while the other one broke of in 2 years.
So I was wondering whats the difference between front and back teeth’s and why they last different after the nerve was removed?

Front teeth typically have only one root. Therefore, normally you have to get treated only in 1 canal.
Top Premolars typically have at least 2 canals. Molars 3 or even 4 canals.
Lower Premolars typically have 1 canal and sometimes 2.
Canines are the strongest built tooth in each arch. The root is the longest and the cross-sectional measurement is also the higher than a premolar even if it has a single root.
Therefore, it is stronger and durable as a result of its bulky structure.
