Could You Please Tell Me How Long the Effects of Botox in the Jaw Muscle for TMJ Will Last?

Asked By:cassie43

Just over a couple of months ago I had my upper and lower jaw muscles injected with botox to relieve the symptoms of TMJ, however about 2 weeks after the treatment I noticed I can't smile as wide as I used to and one side of my mouth looks like it is drooping when I smile. I have had the treatment before and it was successful, but I only had botox injected in the lower jaw muscle that particular time. I am a little concerned as I don't want to look like this permanently.
