when you are so high on drugs, that your teeth feel like they are splitting/being broken by someone or something.
It can also mean that you are about to overdose if you feel this sensation inside your mouth. It is highly dangerous to be " cracked off your teeth" and you could become reckless towards members of the public or to people you may know.
