Botulinum toxin is a purified neurotoxin that temporarily relaxes overactive muscles by blocking the release of acetylcholine, a neurotransmitter responsible for muscle contractions. While commonly used for cosmetic purposes, Botox is highly effective for TMJ disorders, bruxism (teeth grinding), chronic headaches, and migraines, reducing muscle tension and alleviating pain.

Most patients experience relief for three to four months after treatment. However, the exact duration can vary depending on muscle size, activity level, and individual metabolism. Some patients may experience longer-lasting relief, while others may need more frequent treatments.

Many patients start noticing improvement within 3-5 days, with maximum effects occurring within 1-2 weeks. For larger, overworked muscles, such as the masseter (jaw) or neck muscles, it may take longer for full relaxation and pain relief to set in.

It depends on your specific condition and response to treatment. Some patients find long-term relief after just one treatment, while others benefit from regular injections every 3-6 months to prevent pain from returning. Over time, the injected muscles may atrophy (weaken slightly), reducing the frequency of treatments needed.

 Because very small needles are used during injections, pain is usually low. It can feel like a pinch, but goes away quickly. Numbing creams can be used, if the patient prefers.
