Sudden Onset of Jaw Clicking
I think "clicking" is the proper term. This came on suddenly last week. When I eat, or yawn, or otherwise open my mouth fairly wide, the left side of my jaw makes a sound that's pretty audible. There is no pain, and I have had no trauma or otherwise unusual circumstance leading to this. I did chomp on some smallish pieces of ice over the last few weeks; that's the only hard thing I can think of chewing. I do have a back molar on that side (upper left) that needs a crown, but it has needed one for at least three years now (I keep putting it off). I grind my teeth at night and have worn a night guard every night for at least the last 15 years. Any ideas what this is and whether it will resolve itself on its own? Also, if I make an appointment, is this a dentist or doctor issue?
