Re: Jaw hangs lower on one side/ is slanted
my upper jaw is slanted with the left side being higher. The lower jaw is the same. My dentist said its not that unusual and given that both jaws are like that I've probably had it since birth. I went back and looked at some old pictures and that does appear to be the case. Slight, but noticeable if you are looking for it. He said this predisposes me to TMJ problems on the left side, but lots of people are like that.
Mine is permanent so it doesn't change. If yours changes it maybe be the muscles tightening up are adjusting it.
