Recurring ulcer: Any sore or lesion in the mouth that does not heal in 10-14 days, or is recurring, needs to be examined and possibly biopsied. If your dentist is unsure why you are have a lesion, Have the root canal evaluated by an endodontist.

Upper molar crowned, root canaled, if soreness is, due to bite (unprofessional) only, can it still get infected? Assuming root canal was successful.

Upper molar crowned, root canaled, if soreness is, due to bite (unprofessional) only, can it still get infected?  Assuming root canal was successful.

Residual pain: If the root canal was very recent, it is common for the tooth to have residual pain, which should subside. If the the bite is off, a simple adjustment should take care of it. Don't be to quick to throw your gp under the bus! go back and have it evaluated. Good luck. ...Read more

Metal crowned molar( #3) 6 months ago. Soft food is ok to chew. When chewing hard food, very sore to chew. What is it? Bite or root canal?

Metal crowned molar( #3) 6 months ago. Soft food is ok to chew. When chewing hard food, very sore to chew. What is it?  Bite or root canal?

Either: Get the bite checked first. Often times teeth move slightly after crown place ment, enough to alter occlusion and cause chewing pain. Adjusting the bite will solve the problem. If your bite is correct, or if you continue having problems, have it examined by an endodontist for possible endodontic treatment. ...Read more

I had root canal treatment, is it normal that the teeth next to the treated tooth feel tender to biting?

I had root canal treatment, is it normal that the teeth next to the treated tooth feel tender to biting?

Yes this can: Be noted. One possible reson is that the bite load on the treated tooth was changed or even removed as a part of the root canal procedure. This places a little more load/chewing stress on the adjacent teeth. Also, inflammation from the "sick" tooth can have an influence on the neighbors. Explain this issue w your treating dentist. ...Read more

I have symptoms of sinusitis with mild facial swelling. A year ago, I had a root canal on the same side on the upper molar number two with a crown placed. That tooth is tender now. What could be the cause of swelling, tooth or sinus? I am not sure whom to

I have symptoms of sinusitis with mild facial swelling. A year ago, I had a root canal on the same side on the upper molar number two with a crown placed. That tooth is tender now. What could be the cause of swelling, tooth or sinus? I am not sure whom to

Dentist First: From you history, i would start with the root canal tooth, then work from there. It is possible, given your timeline, that the root canal possibly failed, and the infection recurred. If so, treatment is necessary and may allow you to still save the tooth. It is possible it's a sinus infection, but my first guess would be the rct tooth. You want a "pa x-ray", digital if possible, or ct scan. ...Read more

I had teeth #14, crowned, root canalled, 3 roots are cleaned, sealed through bottom of crown, still sore.Can 4th canal spread back to 3, 2, 1 if ..Is?

I had teeth #14, crowned, root canalled, 3 roots are cleaned, sealed through bottom of crown, still sore.Can 4th canal spread back to 3, 2, 1 if ..Is?

No, but: This needs to be checked by your own dentist. It could be an incomplete or failed root canal therapy, a fracture of the crown or root, or simple the tooth is sore from contacting your other teeth prematurely, requiring a simple bite adjustment to resolve. If all normal clinical and radiographic tests fail to diagnose the problem, you might consider a cbct (3d image) to figure out the cause. ...Read more

I have pasta on my teeth but I'm wondering why despite the teeth were sealed outside, the teeth ache after years and it leads me to have root canal?

Pasta?: I assume you mean plaque, an accumulation of bacteria and food debris, or Tarter, calcified plaque. Sealants protect the grooves on the chewing surfaces of the teteth, not the smooth surfaces. Sounds like you have a combination of inproper oral hygiene and lack of regular professional care. Please seek immediate help. ...Read more

Firm palpable lump by spinous process doesn't hurt. Ct scan normal = "normal tissue". Can cause lower front teeth to throb, ache? Even post root canal?

Firm palpable lump by spinous process doesn't hurt. Ct scan normal = "normal tissue". Can cause lower front teeth to throb, ache? Even post root canal?

Probably not: A firm lump on the spinous process of a neck vertebrae can be examined by a primary doctor, and then a neurologist, neurosurgeon, or ENT doctors to get ideas on what it is. If the ct finds no problem, the doctors can help decide whether or not more evaluation is needed. That bump is probably not causing toothache, so the question for one's doctors is: is there something else causing toothache? ...Read more

I have had pain in my back right bottom tooth but it had a root canal. I grind there so is it sore root?

I have had pain in my back right bottom tooth but it had a root canal. I grind there so is it sore root?

Could be fractured: You don't say if the back tooth has had a crown on it, but after root canals, molars can break if you grind on them. Dentists put crowns on these teeth to protect them from fracture after root canals. Get this checked by your dentist - a fractured root hurts in the jaw bone, not in the middle of the tooth. ...Read more
