Medical professionals are increasingly turning to Botox injections in the masseter muscle as a versatile treatment for both functional and cosmetic concerns. The procedure offers patients suffering from temporomandibular joint (TMJ) disorders and bruxism a potential solution for chronic jaw tension and pain.
Dr. Chelsea Venditto, a board-certified plastic surgeon, explains that masseter Botox can significantly alleviate jaw-related discomfort. Patients experiencing varying degrees of teeth grinding may find relief, with some requiring treatments as infrequently as every six months.
Beyond pain management, the treatment has gained popularity for its aesthetic applications. For individuals with masseter hypertrophy, Botox injections can soften a squared jawline, creating a more heart-shaped facial contour and potentially reducing the appearance of an aging or heavier face.
However, medical professionals caution that long-term repeated treatments might have subtle structural implications. Dr. Venditto acknowledges potential concerns about facial soft tissue shifting, though she suggests such changes would likely occur only after years of consistent treatments.
The minimally invasive procedure takes between 15 to 30 minutes, requires no recovery time, and gradually develops results over two to four weeks. As with any medical intervention, individual experiences may vary, and consultation with a qualified professional is recommended.
