Had botox for tmj spasms month ago. i know botox weas off, but is it possible that it'll give muscles chance to heal & effects can b more longterm?

BOTOX and spasm: I use it cosmetically, but it is known that although Botox wears off, there can be some decline in muscles of the face causing hyperdynamic wrinkles with repeated use over years. So, although it may not translate specifically to your situation, you may see some improvement in the long term with TMJ spasms. You would still probably need multiple treatments for longterm success.

Dr Sojico and another doctor agreed

Not likely by itself: If the Botox helps you get comfortable and the underlying cause of the muscle spasms can be addressed, a long term solution may be achievable. Otherwise, the Botox will likely need to be re-administered.

Sometimes: Sometimes a Bptox injection will settle down muscular symptoms. Sometimes the botox injections must be done every 4 months or so on an ongoing basis.

Dr Veres agreed
