You can consider Dysport injection to your larger masseter muscle. After the injection, it takes 1 month before you start to see the muscle atrophy (shrinking). The effect last 4 – 6months.
During this period, you can start to review your chewing habits. This includes having a habit of chewing with both sides of your jaw, avoiding nuts, and consulting a dentist to see if you need a dental mouthguard to prevent teeth grinding at night.
Most of my patients who have one side of their masseter larger do confess that they prefer to chew on that side of their jaw. Hence, after conscious effort to “re-train” their chewing habits, they do manage to overcome this problem, and not need to rely on Dysport/Botox injections. Thanks.
