Abscess on Root Canal tooth

User Level:

Posted by: Maelei  (1 years ago)
Hello, I had an abscess on #19 molar about 6 months ago. I took 7 days of amoxicillin and have decided to extract the tooth if it flares up again. I have had no problems with the tooth since the abscess. I have also beefed up my dental regimen with lots of xylitol. I went to the dentist yesterday and the x-ray is still showing a dark spot or abscess on that same tooth but I have no pain or problems. Is that infection in there or will by body reabsorb in time the pocket the abscess was in? I just want to make sure there is no more infection or I will get the tooth extracted soon. Thanks for your time.

Why would any sane person want an important molar tooth ripped out of their jawbone?

Lack of symptoms means nothing. Don't fool yourself. That abscess will come to haunt you when your immunity drops, and guess what? It may be antibiotic resistant this time!

Thanks Dr. Henry. Well, I am sane and I really don't want to remove the tooth. It had a root canal and crown 11 years ago and I do not want to have any more problems with the tooth. There are no guarentees with the retreatment and that is a lot of money. So, is that still an infection? What is that on the x-ray. It does not look the same as first diagnoised. It is kind of in the middle of roots of the tooth and not at the bottom anymore. I am trying to get an honest answer of what it is 6 months later and if my body will reabsorb whatever it is. Thanks.

In your original post, you did not say that the tooth already had a root canal. That is important info to omit.

A dark spot at the juncture of the roots is completely different from a dark spot at the end of a root. It indicates you have lost bone in the furcation. This is a game changer. Can your dentist pass a periodontal probe into where the dark spot on the x-ray?

You need to sit down and have a long conversation with your dentist, and possibly a gum specialist, before making a decision. The success rates on root canal retreatment drops to about 80%, whereas success rates for implants in the lower jaw is about 95%.

The question is why have you lost bone higher up on the root. It may be a gum problem rather than a root problem. It may be a root fracture. The chance of success depends on the diagnosis, and a diagnosis is impossible to make on an online forum.

Good luck. I hope you are able to save the tooth, but if you cannot, grafting and an implant is a viable option.

Goodness bone loss! So the shadow on the x-ray is possible bone loss from the abscess? Will my body repair the bone loss? If it is a gum issue then bacteia could be getting down there through the gums? How can I strengthen my gums? I have spoke to my dentist and he isn't sure why there is no pain. He said it could have turned into a cyst. But I am not sure what that means too. He was just pressuring me to extract the tooth or retreat. I have an appointment set up for a cleaning at a dental school where they check your gums maybe they can tell me more. Thank you so much for you time I really appreciate it.

The question is, why has there been bone loss?

Could be a failing root canal
Could be a gum infection
Could be a fracture.

How can one be absolutely sure of the cause? The truth is, it is not always possible to know. These cases are sometimes difficult to diagnose. Sometimes I have extracted a tooth that could not be saved, and found no reason for the bone loss- it was forever to remain a mystery. If you got the dental school, perhaps some of the endo and perio faculty can have a lood to see.
