The effects of Botox typically last for 3 to 6 months. As the Botox wears off, muscle activity will usually return, and symptoms may reappear, in which case you can have a repeat treatments to maintain the benefits.

Over time, some patients may find that they require less frequent treatments. This could be due to breaking the habit, or else the muscles may have weakened slightly. Other patients book regular treatments to stop the teeth grinding.
