small absess undr root canalled tooth

Posted by: s10ehhhhh  (8 years ago)
Hi, this is my first post

my last molar on the top right had a root canal done approx 6 years ago, I changed dentist 3 years ago and since then we have been keeping an eye on this particular tooth, because there is a small abscess un der the root, this abscess hasn't gotten bigger or worse, and theres no pain.

I recently got on a good insurance plan and I want to put crowns on my root canalled teeth.

my fist question is, can a small abscess remain as is for a long period of time and not cause problems?

my second question is, would it be worth it to invest on a crown for this tooth, my dentist said she would do it but did says there is a risk because of the small abscess, she also suggested to have the root canal treatment redone by a specialist (which is very expensive, and not covered under my plan)

What do you mean by an "abscess?"

If there is pus draining out of a fistula, you must have that remedied first, and don't even think about a crown until you do.

If there is merely a dark spot that has not regressed over one of the roots (a granuloma) and without symptoms, it is probably worth the risk to have a crown. Sometimes these things never go away completely, no matter how well the root canal is done.

kim, thanks for your response,

initially i though it was granuloma, but recently i have been feeling a little sensitivity behind the molar on the gums (should have mentionned that in the first post) so today i really took a look around there using a little mirror, and i saw what looked like a fistula, i wasnt able to upload a pic, so i put it as my profile pic, please take a look.

as you can see my tooth is in pretty poor shape (almost all filling) Is this a fistula? if so what are my options, can i redo the root canal, is there surgery, do i need to have it extracted?

this is really scaring cause from what i read this can lead to serious problems. i have a dentist appoint next week, so i am trying to get all the info i can before going

if this does lead to extraction, do i really need an implant, i do have an underbite, so my last molar on the bottom is aligned against the middle of the 2 top molars, meaning atleast the bottom tooth would bite up against a part of the remaining molar.

a lot of questions i know, thanks in advance

First of all, always avoid stupid resin fillings like this on upper molars. They frequently cause the root to die, and never last very long.

A fistula looks like a pimple- the middle is draining pus. This picture looks like swelling, but it could just be a variant of bone anatomy. Only an x-ray can differentiate. Also could be a periodontal abscess.

It is hard to do apical surgeries on upper molars, but not impossible. I have even done one on an indispensable upper wisdom tooth successfully, but it was not a fun surgery to do.

It is always better to replace 2nd molars, but no disaster if you lose it. The success ratio of implants is the lowest in that area- but still an impression 90% for non-smokers and non-diabetics.
