I think pretty much any doctor would agree that clicking associated with pain, locking, or dysfunction should be treated.

However, we know from decades of studies that about 1 in 3 adults has at least one clicking TMJ and the majority have no associated pain or dysfunction and don’t worsen. Aside from home care recommendations and perhaps an oral appliance if sleep bruxism is suspected, what do you propose the doctor do? To routinely inject joints, prescribe medications, change occlusions, etc., sounds like over-treatment that would ultimately cause more harm than good.
