Botox for TMJ and slimming for past 2 years/3 times a year. Do I have to continue injecting Botox?

As with all botox injections - the results last 3-4 months and are temporary.  If you are using it for TMJ pain or headaches - then the discomfort will eventually return after the botox wears off.   If you are using if for jaw slimming - then eventually the masseters will increase in size and the jaw will start to look wider again.   It all depends on when the appearance bothers you.   Think of it as similar to coloring your hair for white hair.   The effect is temporary and you do it again when it bothers you.

Thanks for the question.  Ultimately it depends on the patient.  Most patients will need to do Botox every 3-9 months to maintain the jawslimming effects.  However, it is possible that there may be a longer effect of the Botox.  The way you determine that is you wait.  If after a certain period of time you feel the effects wearing off then you repeat the Botox.  This can repeated again and again.

Hi and thanks for your question. Botox injection in the masster muscles to reduce grinding and clenching is a great procedure. It is the only way to really stop the clenching and grinding and it atrophies the muscles, softening the contours of your face. In my practice, patients get 3 - 4 treatments, separated by about 3 to 4 months and that is often enough to kill the habit for a long time. When the muscle no longer gives feedback to the brain because it has been chemically weakened by Botox, the brain stops telling the muscle to clench whenever you experience stress. So, I would suggest doing a few sessions and then stopping to see if you need it any more. Hope that helps.
