S, can I suggest going to see an endodontist, at least for their opinion? They will be able to give you a fairly accurate prediction of success, and if they do the treatment, they will do a really good job!

I totally understand where you're coming from, but you need to talk to your dentist (or a specialist) about YOUR particular tooth. They are all so individual. Sure, some RCTs fail, some quickly, but more often years down the track. If the tooth is a good candidate for RCT, and the treatment is done well, then the tooth *should* last you for some years yet. I can tell you that over the years I've seen many more RC treated teeth last the distance than not . The ones that don't hang in there are few and far between.

Exo and implant is certainly a viable option (and often an excellent one), but very exxy (which I'm sure you know) and is invasive and non-reversible. Personally, I would want to be very sure that my tooth wasn't going to last long before heading down that road.

Can you tell me which tooth it is that's giving you trouble? Oh, and has anyone mentioned the likelihood of this tooth needing a crown after the RCT?
