Could I have TMJ syndrome?

Okay, so to start, I'm 14 years old and I have had braces for about two years, and I'm getting the top ones off next week and the bottom ones off in another month. So about a year ago, when I started wearing my rubber bands (for braces) a certain way, I began to hear a clicking or popping sound in the right side of my mouth whenever I opened or closed it and also whenever I opened or closed my mouth, on my right side, I would always feel like there was a bone right near my ear kind of popping out of place and restricting me from opening my mouth anymore. But when I would open my mouth wider, it felt like that bone would pop back into place and I was free to open and close my mouth without any problem. But it would come back after I relaxed my jaw. I began to notice that whenever I would slide my jaw to the left a bit, I would avoid this sensation. If I opened my mouth without sliding my jaw to the left, I would feel that bone popping out of place and hear that clicking sound. After a while, it started to become slightly painful and intensify. I mentioned it to my orthodontist but he said that it was probably just because the braces were moving my teeth around, which is what my brother said too because he said he had the same experience when he had braces. As the days went on, it started to intensify even more, but it became less painful. So today, I cannot open my mouth as wide as I can without sliding my jaw to the left because now when I feel that bone popping out of place on the right side, I can't open my mouth any wider to pop it back into place. I've gotten used to it and I'm in absolutely no pain at all anymore. What's worrying me now is that within the past couple of months, I began to notice a similar popping sound and bone movement on the left side of my mouth. I read up on TMJ syndrome because I heard about it online and the symptoms that fit me were the popping/clicking noise when I open my mouth and restriction to open my mouth as wide as I usually can. The causes that fit me were excessive gum chewing and excessive grinding of the teeth. I used to chew a lot of gum, even when I had braces and ever since I was little, I would grind my teeth as a habit. Kind of like if I'm listening to music, I will grind and kind of hit my teeth together to make a sound in my head that goes along with the beat of the drum in the music I'm listening to. It's become a habit that is extremely difficult to stop. So I'm wondering if anyone thinks I have TMJ syndrome because my family and my ortho does not seem to agree with me. I don't want my jaw to dislocate so my mom agreed to take me to the ear, nose, and throat doctor that she works for because apparently my aunt had a similar problem and he told her to stop chewing gum. Any tips on treatment or what do you think my problem is? Could I have TMJ syndrome? What should I do if I do have it, should I see this doctor or someone else? And remember, I am not in any pain at all. Thank you.
