Do you know why your jaw broke ?? Because of the extraction or because of the cyst ?
WW said it.
Such cysts are not that uncommon, however doctors don't know what causes them or why.
First of all I have no symptoms. Nada. Zero. I had no sign there was a problem. I have good, strong teeth and I'm in excellent health.
Cysts like this grow about .5mm per month. That means my cyst had been there for almost a year and a half.
It "eats" the bone which, of course, causes a structural weakness. It's unclear whether such cysts offers any substitute strength.
Depending on the cyst there are two ways to access them: from the side---in my case, it was on the inside of the jaw---or from above.
The definitive scans showed the roots of the last molar *possibly* inside of the cyst which could have killed the tooth. That was the reason for the root canal first: secure that molar. That would have meant the cyst was *inside* the jaw and could be problematic.
Fortunately that wasn't the case. The cyst was outside the jaw on the inside, all covered with gum and tissue.
There are two ways to extract it: 1) from the side, literally cutting a 1" flap in the gum (radical) or 2) from above, removing the (in my case, healthy) wisdom tooth.
The first surgeon we visited (the one without a name) wanted to do #1, which is a somewhat radical approach. We opted for #2 in a step-by-step approach.
We also figured since the lower wisdom tooth was coming out, by face would be numb, so we might as well whack the upper also. The difficulty was that both teeth were healthy. Bad or impacted teeth with infection come out much easier. Mine were in solid.
Once the lower wisdom tooth was out, the oral surgeon cut deeper until the cyst was lanced. He physically drained & flushed it of the contents, and injected powerful antibiotics in it's place.
We just didn't know how weak the jaw bone was. That's what I'm living through now.
The knowledge is out there in the Dominican medical community. One must edumacate himself on one's conditions to make sound judgement on the options available of patient plans.
BTW: the cyst had dissolved about 65% of the mandible in one area.
I'll try to scan the CT & xrays to show what the docs saw.
