I have been recommended jaw botox to reduce my chronic pain. I am also pleased to hear it will reduce the size of my jaw muscles aesthetically, but I would like to know how much would usually be administered for an aesthetic effect?
How Many Units for Aesthetic Jaw Botox?

Botox or Dysport for large jaw muscles (masseter)
I also tend to use 25 units of Botox per masseter per side (50 total). I tend to use about 60 unites of Dysport per side.

The injection technique does vary by physical exam and the goals of the treatment. Facial contouring goals may change the injection sites themselves to affect different portions of the masseter as well as the dose. The strength of the masseters can be felt by palpation and also helps me to determine dosing. In general, I start with 15- 25 units of Botox (OR 50-75 units of Dysport) per side for most patients. If they have very strong masseters, then I may increase the dose, but more commonly ask them to return in three weeks for a touch up. Once you get the desired result, I let patients know that future treatments may require less to maintain the look or the jaw clenching symptoms, especially if they get treated as soon as they notice the symptoms return. This can be as soon as three to four months, but in some cases, patients report that it lasts six months or more. I find it depends on the dose we use and how many times we have done the procedure as the duration may lengthen for patients that repeat it regularly.
