but not as a teen, in my early 40s, to correct TMJ. One of my 50ish coworkers has them now and he tells me he sees an 80 year old woman in the office on a similar schedule getting them tightened. Ouch.

A buddy in his late 20s is getting them now, too. He was beaten so severely by a couple muggers that his jaw and teeth were damaged.

It's not as unusual as you may think!
