I had a root canal done in my molar. after one month i felt pain while eating on it. i went to the dr. and he told me it's broken into two halvess i don't want to remove it if at all possible. do i have other options?

Fractured tooth: In certain instances, a fracture makes the tooth non-restorable. The initial pain could have been from the fracture, only it was not evident to your dentist or it could have fractured afterwards. A dental implant would probably be the better way to restore the site once the tooth is extracted.

Nature will prevail: Most rct teeth that fracture in half require removal. No one can force you to have treatment that you do not want. However, if the tooth is unrestorable, as advised by your dentist, and you elect to just leave it, in time you are almost guaranteed pain & swelling & have less options & more problems. Sometimes one has to accept the inevitable and cut their losses early. If unsure, seek 2nd opinion.

Need follow-up SOON!: If a back tooth requires rct, it typically requires protection with protection either with a crown or an interim "build-up" which covers the whole biting surface. Otherwise, the tooth can fracture vertically into the root, which is what your situation sounds like. If this is the case, the tooth may be non-restorable, and will become infected and more painful if not treated soon!

Rct molar: The only solution for tooth fractures is extraction. Even hairline fractures can continue to be a source of irritation and are often difficult to diagnose.
