Ok, I missed the length before - this could be d-latum (fish tapeworm); it's been diagnosed in me and it's the longest tapeworm.
it must be it then because this is extremely extremely long and as you described, it just tangles around the teeth and the whole face (in additon to the whole body)
I am actually glad that someone else feels this too, it's been unreal to deal with them and the worst is that they get into the body tissues, in no way they stay in the intestines only as everything you can read about them would suggest - obviously nobody does research this so nobody truly knows, only the sufferers
some time ago I posted article about the parasites where they admitted those were found in the US and one of them was diphilobotrium latum (d-latum) - fish tapeworm, apparently someone even filed a court case against the restaurant where the person got infected with the fish Tapeworm - no wonder, after experiencing so much suffering and pain because of this I would totally do the same if I knew where I got infected
most horrible is that nobody knows what can happen, this is not talked about at all - you can't read about this (and learn about the danger) in no medical paper/article or whatever information I was able to find on the internet
