If you have experienced chronic pain in your jaw or into your temple, or your dentist has brought to your attention the breakdown of your teeth from grinding, you may need to pay more attention to your masseters.

Masseter Botox is a highly effective, non-surgical treatment for jaw clenching, teeth grinding (bruxism), and muscle-related TMJ discomfort. By gently relaxing the overworked masseter muscles, this treatment helps relieve jaw tension, reduce facial pain and headaches, protect teeth from grinding damage, and create a more relaxed, balanced jawline. 

After treating with neurotoxin, you should notice an improvement in jaw soreness and clenching within the week, with results lasting for months. In addition to pain relief, masseter Botox can also soften a bulky or square jaw caused by chronic clenching, offering both therapeutic and aesthetic benefits. 

A systematic review and meta-analysis of randomized controlled trials found that glabellar Botox significantly improved depression scores compared to placebo at about six weeks after treatment, supporting a possible antidepressant effect. 

What does this mean? 

It means that early research shows that Botox may offer benefits beyond smoothing wrinkles — including a positive impact on mood and emotional well-being. Studies have shown that treating frown lines with Botox can reduce negative facial expressions, which may interrupt stress and tension signals sent to the brain, a concept known as the facial feedback hypothesis. In clinical trials, patients receiving Botox in the upper face reported improvements in mood, happiness, and even symptoms of depression compared to placebo. While Botox is not a treatment for mental health conditions, these findings highlight how looking more relaxed and less tense may also help patients feel more confident, uplifted, and emotionally at ease.
