Botox for Crows Feet Has Caused an Uneven Mouth and Discomfort in my Jaw?

It is unlikely that Botox injected into the crow’s feet region would have an effect on your jawline. However, if the injection was misplaced or too much Botox was used, it may have inadvertently affected the zygomaticus muscles, especially on the right side where your smile has been affected. The discomfort in your left jaw is very strange and I advise you to return to your doctor regarding this. In any event, Botox does wear off in 3 to 6 months, so these reactions should subside.

It's hard to say without assessing you in person what may or may not be going on, however I wouldn't think Botox placed in the "eye area" would have any affect on your mouth. IF the Botox was injected into the wrong muscle causing one side of your mouth to droop, you would have an uneven smile. Follow up with your provider so they can see what's happened.

Hello Emma,

The botox may have temporarily weakened the zygomaticus major or minor muscles, which are used to elevate the outer corner of your mouth. Weakness of these muscles would result in mouth drooping. Luckily, the effects of botox are temporary and will wear off with time. Hopefully the drooping will get better over several weeks, but it may take several months for it to resolve completely. Make sure you discuss the issue with your provider.
