Abutment teeth
is it ok to use a tooth that has a more than 10 years root canal history and a newly developed deep decay, and more than half of the tooth is gone after cleaning the decay, to use it as an abutment tooth? Thank you!

Answer: Abutment Tooth
By Sarah h
Dental Professional
Assuming you are referring to a molar (2-3 roots), if the tooth doesn't have root caries or furcation involvement, the tooth is most likely strong enough to support a 3 unit bridge. It is best to see a dental radiograph in order to see the remaining tooth structure a well as the other abutment tooth/teeth. Your dentist would prepare you if the tooth was not strong enough to support the bridge, as they do not want their restorations to fail.
