I WOULD NOT RECCOMEND U WANTING TO CRACK YOUR JAW. I've been doin this since i was a kid. I'm trying to stop. But here's how i do it; and i can only do the right side. I make a fist and make the index finger stick out a little more to make contact with the jaw bone a little down from the ear on the side of your face and tense my jaw muscle and then untense it and then hit it with the index finger. It sometimes takes a while. Since my finger has been getting soar from hitting it i use a small hammer. I know this sounds weird..but it works for me. Happy cracking!!

I can only do the right side too. I sometimes have to use a small hammer to get it to crack. And i can do it repeatedly by tensing up the jaw muscle. I only got the left side to crack only a few times in my life.

I'm 53 years old and have been cracking my jaw since i was about 13 years old. I can only get it to crack on the right side. I know this is going to sound bizarre but i do it by either hitting my jaw bone from the side where the jaw curves down a little below the ear and if i cant get the pop by by hitting it with my fist i use a small hammer..weird huh. Of course i can't do this in front of anybody, they would think i'm nuts. I never get any TMJ or jaw pain but i'm worried about causing damage to my jaw and i'm trying hard to stop this weird habit.
