This has driven me nuts since I was a child. On my top right row of teeth there is a constant itching between two of my molars. The only solution to this itch is to either tongue at it constantly or do what i really want to do, which is to find a toothpick or my nail and jam it in between my teeth and dig around. The latter solution will cause my gums to bleed a lot, but it feels good for just a moment. Actually, I wouldn't say good, more like i hit a nerve cluster or something. Can anyone tell me what is causing this? I can go years forgetting the itch is even there and then just one day its back. I hope someone on reddit can tell me how to get rid of this once and for all.
