What is Botox?
Botox is a manufactured form of Botulinum Toxin (type A). It is produced through fermentation of an organism referred to as Clostridium botulinum and is then purified, concentrated and sterilized.
How does Botox work?
When injected into a muscle, Botox reduces the muscle activity by causing a partial chemical denervation of the muscle, resulting in localized decreased muscle activity. It usually slowly degrades, and new injections need to be performed every 3 to 4 months to maintain its effectiveness.
How is Botox used in TMJ or TMD therapy?
Many patients who are diagnosed with TMJ or TMD problems also have chronic muscle spasm and muscle pain. This often results in decreased opening, pain with opening, pain with chewing, or persistent muscle pain that is not responsive to oral medications or other treatments. In these patients, Botox can be used to help reduce muscle activity and muscle spasm significantly, thereby reducing symptoms and improving functions such as chewing and speaking.
What are the risks of Botox?
Injections of Botox into the muscles in the face can result in soreness or tenderness of those muscles for several days. Bruising is also possible at the sties of injections. Additionally, it is possible to have weakness of some of the facial muscles around the mouth, nose, eyes, or forehead that would be a temporary problem, but could last for several weeks. Allergic reaction to Botox is unusual.
