Yes that resonates with me as well. Im a notorious teeth grinder. Cracked some fillings in the process.

I now also have a special dental mouthguard that i wear when i sleep.

But still i also think in the unconscious, teeth have special meaning.

Yes to the carrier wave, which i really like. No to teeth falling out however i did have a stage where i thought i had broken glass in my mouth. To such an extent that i thought i had bitten the end off my bong, even though it has a metal mouth piece?!
