Patient's Query

Hello doctor,

I have the first upper molar root canal treated 15 years ago. It has undergone two root canals treatment but does it seem incomplete? I did a CBCT and it shows a cyst and sinusitis although I have not that much pain. I am 41 and the dentist told me that I have bone resorption at the upper left maxillary region and I also have been recently diagnosed with Hashimoto thyroiditis. Should I get the tooth extracted? Should I try again for a new third root canal? What about periodontitis which is at the beginning?


Welcome to icliniq.com.

At first, I appreciate you because you have so much awareness of your oral health. The life span of normal root canal treated tooth is 5 to 6 years. If you have 15-year-old treated tooth, it means you are so health conscious and take care of your oral hygiene. My opinion is you should go for extraction along with cyst removal because third-time root canal of the same tooth is not a good idea. Periodontitis is nothing but an infection of gum tissue which is totally curable and depends upon your oral hygiene.

Bone resorption is a kind of bone loss due to demineralization. There are many things which are responsible for that like age factor, some diseases, calcium level, gingivitis with periodontitis is also a cause of bone loss.

Same symptoms don't mean you have the same problem. Consult a doctor now!
