How bad does a tooth have to get before it can't be saved by root canal treatment?


Answers:    i don't know if this helps but a couple of years ago i had the most terrific pain in my tooth it had a huge hole in the back molar and i had lost half the tooth i thought it would have to be taken out but the dentist said no i needed root canal treatment they cleaned the tooth out and packed it with a gauze then i had to come back and have it filled with a root canal filling by that time more of the tooth was coming away but my dentist said the tooth could be saved i have had it refilled twice now and i would say there is more filling than tooth but my dentist said even the most rotten tooth can be saved if the nerve is causing the problem because its the nerve that causes the pain and if its a permanent tooth they would rather save it than take it out good luck
a root canal takes out the tooth and the root and then they replace it with a fake tooth. so if you get a root canal your tooth has already gotten bad.
It would have to be really bad, like bone degeneration in your jaw- they would have nothing to anchor the root to.
It would have to get back and very weak. When they do a root canal they grind down most of the tooth, but leave enough to build up on. Then they put a cap on it. Now if the tooth is too broken, then it would have to be pulled. I Know from experience. I cracked a tooth in half both ways, and they couldn't save it.
Good luck.
ADRIAN,

THE ONLY REASON TO NOT BE ABLE TO SAVE A TOOTH WITH A ROOT CANAL IS THAT THERE IS NOT SUFFICIENT BONE SUPPORT FOR THIS TOOTH.SINCE A ROOT CANAL ONLY REMOVES THE NERVE AND SMALL BLOOD VESSELS FROM A TOOTH, THE TOOTH EVENTUALLY BECOMES BRITTLE AND WILL NEED A CROWN BEFORE IT BREAKS.
IF THERE IS NOT ENOUGH BONE TO HOLD THE TOOTH A ROOT CANAL IS A WASTE OF GOOD MONEY.
It depends on how badly the decay is in the tooth. Once all the decay is removed and there is not enough tooth structure left of the tooth,or the decay was so bad that the decay went into the nerve,then the tooth would be considered hopeless and it will need to be extracted.
Sounds as though the tooth is very weak,if it cracks into the gum there's nothing to be done.It hs to be removed.
A tooth can crack down its root and may not be able to be saved by rct. This can happen simply by biting down hard/or the wrong way on something. A root canal will not work as once its filled, the tooth continues to flex letting in bacteria. Also, a tooth that has bad decay that extends below the gum line may not be able to be saved. If your Dentist suggest rct get it sooner than later as it will be less expensive in the long run as opposed to replacing the tooth with bridgework or an implant or a denture. Also infection may soon follow.
Root canal treatment (RCT) involves removing the nerves and blood vessels that occupy the canal of the tooth root - in a molar tooth there will be a canal in each root. The empty canal is then filled with an inert material to stop infection getting into the empty space. Almost always this procedure is needed where a tooth has a large hole such that the decay has pentrated down to the tooth pulp and the delicate tissue is infected with bacteria.

For a tooth to be so bad as to not be saved by RCT one or more of the following will apply:

a. Very little sound tooth structure left once the decay is fully removed.

b. Disease of the bone surrounding the tooth (periodontal disease) to an extent that the root(s) is poorly supported.

c. Inability to carry out the RCT because of anatomical difficulties in the tooth.

d. History of failed RCT in the same tooth.

e. Patient has high caries risk and will not modify diet/oral hygiene to reduce the risk.

f. There are certain rare medical conditions that contraindicate RCT

Mostly, though, as long as there is sound tooth tissue to work with RCT will save very broken down teeth and the tooth can be repaired after the RCT is complete. Can get expensive of course - sometimes it can be better to just lose the tooth and get over it!
In my case the rot had seeped down below the gum-line and before I knew it - crack. The lower it goes the harder it is to fix. I had to have the tooth out because it was almost shattered. Only the one tooth in the whole mouth was bad, though. Strange.
