I seriously hope OP made a typo and wasn't asking what they wrote! 😂

Maybe from clenching?

More like a scream than a tingle…

I’ve heard of a poop knife but this?

You can't feel with your teeth. It's an instinctual reaction to the pitches of vibration your teeth make when they're damaged.
The metal thing has something to do with the nerves in your teeth, but i don't remember exactly how.

Nerve fibers in the periodontal ligament react to the slightest displacement of your tooth.

yes, there are (hopefully) no teeth in your bowel

Short answer is they don't. Different people have different triggers which "go through them" as the saying goes. While someone might hate the sound of chalk on a blackboard for others it makes no difference.

Why you're teeth hurt is a good question, teeth can only feel the sensation of pain. It might be the case that anything particularly abrasive to your ear or eyes might cause an involuntary react in your mind that causes something akin to anxiety to occur.

Experience has taught me that your teeth and ears being close in proximity is the answer. I had an abscess tooth once that everyone thought was molar, I was about 21 or so and I had no issues with my molars.

No sooner than my face swelling did my dentist notice it was an abscess that it was removed. Along with my molars because everyone’s have to come out. Everything that I would hear would hurt my teeth and back again. The dentist explained that it’s normal, your nerves are all connected. It’s the nervous system, however your teeth and ears being so close they tend to hurt together.

Your body registers pain and that pain must be dealt with, your teeth tell the brain and the ears get the emotional baggage.

Teeth +aluminum = battery.... It's called a Galvanic shock... When you chomp down on aluminum the electro chemical difference coupled with saliva provides a salty environment. You get a pretty painful shock of voltage.

Um, what? This does not happen to me.

I've never thought about this, but I suppose it is crosstalk from the temporal lobe, where there is audio processing, onto the primary somatosensory cortex, which does the sensations around the mouth.

Do you mean where you have something metal in your mouth and you get a strange sensation from it?

Sometimes in the mouth, I can't stand metal spoons while eating ice-cream. But in general, hearing metal scraping makes my teeth tingle and causes huge discomfort. I know some people have agreed on it but some don't get it at all
