I've had 2 separate Botox injections (3-4 months apart). I've developed dry mouth recently.

Masseter muscle injections could set you up for temporary dry mouth. If your objection was I the upper face, then it's unlikely to be Botox. Dry mouth can be caused by several other conditions and you should discuss your concerned with your injector.Best wishes, Dr. Aldo

Botox is unlikely the cause of your dry mouth.  If you had botox injected into your masseter muscle than it is possible to have dry mouth as a side effect, that is temporary.

Thank you for your question.Where did you have the Botox injected? If it was injected in the Maseter it may cause some dry mouth but that would resolve after a week or so. If it was injected in the upper facial areas, I would find it very unlikely that the two are related. 

I'm not sure where you had your injection. Botox injections to the masseter could cause dry mouth, but it would resolve in a week or two, but this would be extremely rare. If Botox was injected somewhere else, it's unlikely it is due to your injection. If it persists, I recommend getting a formal evaluation with your Doctor to determine cause. 

Thank you for your question. You do not mention where you received your injections. If you had Botox injected into the masseter muscle then it can cause dry mouth. However, this would resolve in 1-2 weeks. If you had Botox injected anywhere else it is very unlikely to cause dry mouth. If this continues I recommend having this evaluated by your doctor to determine the cause. Best of Luck!
