My back tooth still hurts after root canal and crown, what are my options?

See an endodontist. You should get a second opinion with an endodontist about all of your options.
Re-evaluation. The dentist(s) treating you need to reevaluate this tooth to determine why you are still sensitive. Please call for a follow-up appointment.

Just lost a crown on my lower back tooth. It already had a root canal couple years ago, the tooth close to gum line, do I have to get a crown now?

Get i replaced. Once a crown is lost, even with a previous root canal, the tooth is subject to decay, movement and gingival (gum) overgrowth. This can lead to more compliated procedures such as surgery before the crown can be replaced or it can even cause the loss of the tooth. Read more...
Would need to. Be clinically and radiographically evaluated by a dentist to see if restorable. Better addressed sooner rather than later as later might be non restorable / irreparable. Hope this helps. Read more...
Need crown. The tooth is more brittle and needs the protection of a crown. You might need a "crown lengthening" which exposes more of the tooth so a crown will fit properly. Read more...
Get it checked. It would be wise to have the tooth looked at critically to determine why the crown came off. If it was due to a deficiency in the structure of the underlying tooth, this will need to be corrected or the problem could keep recurring. If it was a material failure, the chances of success are higher. Read more...

What is it like getting a root canal on upper back tooth if TMJ and limited ability to open? Solutions?

Root canal with TMJ. If you need a root canal, then you need a root canal. The only alternative is extraction of the tooth. These days, with good local anesthesia, a root canal should be painless. If you can't open wide enough, it may be necessary to treat the TMJ problem first. This starts with finding out what the problem is and where it lies, whether in the muscles or the joint itself. This may require a TMJ mri. Read more...
Options. The dentist can give you a muscle relaxer pill to relax the muscles which will allow you to open wider with less strain during the appointment. Read more...
Might be impossible. See an endodontist. If he can't get access, you either have to see a TMJ doc to get you open wider, or have the tooth extracted. Read more...
Top docs! While it is theoretically possible that if you can't open your jaw wide enough and\or the tooth presents with a difficult access and angulation issue, RCT might be impossible. You would then have to have the tooth removed. However, in 40 years of dental practice, I honestly can't remember not being able to resolve this issue. Discuss with an Endodontist and a dentist who treats TMJ\TMD issues. Read more...

Can I have just 1 root taken out of a back tooth and how strong will it be. I've had loads of infections in just the one root and 3 root canals.

Hemisection. Yes, sometimes when one root is the culprit of many recurring infections, a removal of just the one root can be done. This is called a hemisection. An oral surgeon or endodontist should evaluate the long-0term prognosis of the tooth to see if this is an alternative for you. Read more...
You could, but. I am assuming you have had three root canal procedures performed on the same tooth that has the problematic root. Has the option of an apicoectomy been discussed or offered? You can have just one root removed (root amputation or a hemisection) performed, but with a history of three root canal procedures, is saving the tooth the best option or removal and consideration of an implant better?
