My jaw pops when i open it . no pain. just very annoying. is this tmj? do i need surgery ?

No need for surgery : Its likely TMJ which can be treated with conservative treatment, specific exercises, dental appliances, and even manipulation. Surgery is last resort.

TMJ: This is what is referred to as TMJ or tmd. Surgery is not recommended, unless you are in extreme pain and this is often used as a last option for treatment. Often times TMJ popping can be caused by a bite discrepancy. Have a dentist versed in bite analysis evaluate your bite.

Probably no, but: Most likely you are experiencing slippage of a doughnut-like cushion in your jaw joint. Try to limit this popping sound from occurring . Pain may occur in the future... See your dentist to see if this is treatable!

TMJ: Yes, a symptom of TMJ. No surgery except unusual circumstances. See specialist. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask your MD, your dentist and your dental society for referrals.
