Oral Surgery/Jaw Problems and Sudden Lisp


I have had minor issues with the left side of my jaw popping for several years, possibly brought on by wearing Invisalign orthodontia. I suspect it might be TMJ, though I haven't been formally examined. I was instructed to wear the last set of aligners occasionally at night to act as a retainer. This week, after not wearing for a couple weeks, I put the aligners in. When I woke up, the right side of my jaw seemed misaligned, it was painful, hard to open my mouth, and I heard cracking and popping in my ear. The pain, sounds, and mobility issues seem to have mostly subsided, but I am now experiencing a slight lisp when pronouncing /s/ sounds. I have never before experienced speech impediments. Will this subside as well, or is it a more serious problem for which I should seek treatment?

Thanks for your help.


I hope it subsides.  But you have to be examined. I suggest to see a board certified oral surgeon who does jaw surgeries and a good orthodontist.  Maybe Invisalign was not the answer to your problem.  But you should be seen soon before further damage to TMJ.
