I had Botox in my masseter done around 5 days ago. When I eat & chew now my jaw muscles protrudes outwards and looks weird.

Question

I had botox injected into my masseters around 5 days ago. A couple days after the injection, I have been noticing that whenever I eat and chew, my jaw muscles protrudes outwards and makes my jawline look very weird. It actually looks like the masserter has gone larger. Just wondering if this is the botox working or is it a side effect. I have heard it takes a couple of weeks to see results, so maybe the muscle will eventually go down and it won't protrude out when I chew?

You may have some swelling or it may be surrounding muscles engaging to work for the treated muscles. However, it can take up to 2 weeks for final results. I would wait a full two weeks before assessing results. Hope this helps.

The masseter muscle is one of the most popular places to have injected to make the face slimmer. However, it sounds as if a different place was injected and you should return to your treating physician to have Botox injected to compensate those injections.  Best, Dr. Green

Steven M. Daines, MD, FACS · Answer

Botox in the master muscles can slim the lower third of the face and also help with jaw pain from excessive clenching. Early asymmetry after treatment is common as the muscles adapt. A follow-up treatment 2 weeks later can help target areas where the muscle has overcompensated.

Tom van Eijk, MD · Answer

The masseter muscle at the jawline basicly has two layers. When only the outer layer is hit by the botox in deeper muscle tends  to protrude. Please get back to youjr practitioner and he or she can correct it by addressing the deeper muscle also.

Leonard Grossman, MD · Answer

I think that most likely you've never looked at your face while you were chewing prior to the treatment. Now that you've had the treatment you're more observational of yourself. This is the reason why you see the movement that you haven't seen before. Good luck from New York City
