20 years post O Surgery, can a mandibular extraction cause TMJ

I am 20 years post Orthagnathic surgery. I needed a molar to be extracted on lower right. I had terrific pain in my left jaw during extraction. i have worked in the dental field for decades. I asked the doctor to please section my tooth at that painful moment. that was 2 1/2years ago. my left condile is flat now. I have TMJ pain and muscles spasms every day. Especially after talking for a while and of course chewing . My husband is an Orthodontist. He made me a splint which seems to work well after wearing over night. But mid day, everyday, its back !

Answer: Idiopathic Condylar Resorption

By BracesInfo.com Expert 10

It is not likely that the extraction or trauma created during single tooth extraction caused the loss of vertical dimension in your condyle. What are you describing sounds like Idiopathic Condylar Resorption (ICR). It occurs in about 9:1 females to males. While this disease is well documented, it is poorly understood. Many say that it is linked with orthodontic treatment and orthoganathic surgery, however with no direct cause-effect relationship, it may be coincidental. The recommended treatment is splint therapy as well as additional surgeries, however nothing can completely cure the resorption just slow the progression and minimize the pain significantly.
