Please help! Tooth pain years after root canal?

Please help! Tooth pain years after root canal?

Bummer: Root canals may fail over time by loosing their seal. Another possibility is a cracked root. My advice would be to see an endodontist, root canal specialist to evaluate whether the tooth can be saved. 10 year on root canals is around 90%.

I've had tooth pain on the tooth I had a root canal on 5 years ago when chewing. Sometimes unbearable. Could it have something to do with infection?

See your dentist: If you have a tooth with an old root canal treatment and it has started to show, any type of symptoms like pain or swelling, it should be examined by your dentist for possible infection and re-treatment.

Tooth pain since having root canal and crown in January. Doc has adjusted bite. Still hurts. Want to have it pulled. Do u have to have abx for tooth pull?

See an endodontist: Endodontists are dentists who have at least 2-3 years of advanced training in root canals. They are experts at diagnosing complications after root canal treatment and use advanced special equipment to treat patients efficiently and comfortably.

Tooth pain started 3 weeks after perm crown. Dentist: wait, see if the nerves correct themselves. Root canal? Wait? Heat hurts and can't chew food

RCT: Sensitivity to heat is especially a classic sign of nerve involvement and the need for root canal therapy. Pain on biting pressure can be merely the bite being high and the need to adjust the bite. However, both symptoms combined along with the course of events that you describe would make the need for rct very likely. I think 3 weeks is long enough to wait for resolution. See your dentist now.

Crowned tooth pain/possible missed 4 canal from root canal 2 years ago I had a root canal and a crown. When I finally settled on my current dentist (for insurance network reasons) I had a root canal and crown. The first 2 dentists said I had a 4th root so

Crowned tooth pain/possible missed 4 canal from root canal 2 years ago I had a root canal and a crown. When I finally settled on my current dentist (for insurance network reasons) I had a root canal and crown. The first 2 dentists said I had a 4th root so

See Endodontist: 95% of upper molars have 4 canals. The missed canal is called the mb2 canal. Microscopically trained endodontists are adept at finding and treating this problem. I suggest you see one asap. In the future, suggest to your dentist you want to see a specialist. You are in control of your treatment!

I've had a recurring sinus infection, coupled with severe tooth pain. Do I possibly need a root canal?

I've had a recurring sinus infection, coupled with severe tooth pain. Do I possibly need a root canal?

Maybe...: It sounds like there is an infection that is tooth related. If this is the case and your tooth can be saved, a root canal may be your answer. There are too many issues to resolve without a professional evaluation. See your dentist asap and get well ;-).

Gum slicing pain from extraction a year ago. Recent Root canal, another extraction, causing more severe gum & tooth pain. 5 dentist & oral clueless.

Gum slicing pain from extraction a year ago. Recent Root canal, another extraction, causing more severe gum & tooth pain. 5 dentist & oral clueless.

Proper exam: You need to do your homework and find the right place to go to, an oral surgeon or a qualified dentist who can give you the proper physical and radiological examination to reach to a diagnosis and a treatment plan for your condition, weather it's a remaining root from previous extraction or remains infections I'm sure it can be taken care of.

Tooth pain in several teeth from just heat and x-rays came out negative. I have deep fillings on one of my teeth. Do I need a root canal?

Tooth pain in several teeth from just heat and x-rays came out negative. I have deep fillings on one of my teeth. Do I need a root canal?

Yes and No: You need a root canal if one or more of your teeth have irreversible nerve inflammation, or if the tooth or teeth are dead or dying. You don't need a root canal if the pain-causing inflammation is reversible. You may need to replace the deep filling with a sedative liner and a new filling. You may also need to do a bite adjustment. You should probably see an endodontist for a 2nd opinion.

Had a root canal on wisdom tooth. Pain for three weeks. Pain reliever Round the clock. Pain in cheek and jawbone. Half of face with teeth in pain.

Had a root canal on wisdom tooth. Pain for three weeks. Pain reliever Round the clock. Pain in cheek and jawbone. Half of face with teeth in pain.

See specialist: Have you been in touch with the Dentist?? If a specialist did the treatment, they would want to see you ASAP to address this issue. If not done by specialist, then you should see an Endodontist for evaluation and treatment. My concern based on your report is that you may have cracked the tooth, and if this is the case, it will need to be extracted. Good Luck -- Make Appt.

See dentist: Return for follow up with the dentist who did the root canal or get a second opinion. It is possible on lower teeth to get inflammation in the nerve canal that runs inside of the jaw bone. This pressure will cause everything along the whole side to hurt. Seek follow up care.

Cramp like tooth pain to hot foods. Light tapping causes ache. Xrays shows nothing. Endo say root canal not necessary. Am uncomfortable, what next?

Endo second opinion: In many cases, seeking a second opinion is not only warranted, but necessary. Unless your disease is life threatening and requires emergency care, it is never a bad idea to seek a second opinion. Getting a second opinion helps you feel more confident about your diagnosis and treatment plan. See a board certified endodontist.

Had terrible toothache in upper left tooth. Pain went away after three days. X-rays-no root canal needed. Gums sore and cheek puffy. Root canal needed?

Probably: Radiographs are not a crystal ball... they don't disclose everything. Did your dentist check to see if the tooth was vital (alive)? Swelling may be from a periodontal issue, so yes, in that case root canal may not be needed. More info necessary to make a proper diagnosis. Have your dentist re-examine you or refer you to an endodontist if s/he can't determine the cause of your swelling.
