This started when I was 18 (I'm 25 now). I still have my wisdom teeth in.

My jaw always pops (painlessly) when I open it completely.

Whenever I do a lot of chewing, it starts getting tighter and tighter and will pop loudly every time I open my mouth to take another bite of food.

If I keep pushing it, eventually it will just completely lock up and I can't open my jaw wider than an inch or so. It doesn't hurt. It is just locked.

After some time as gone by, the jaw relaxes and I am able to open it again.

What type of doctor should I see for this? Ear nose and throat? Oral surgeon?
