Could masseter Botox cause my disc to slip?

Botox injections in the masseter muscle are a common treatment for temporomandibular joint (TMJ) disorders, as they can help reduce muscle tension and alleviate pain. However, Botox primarily affects the muscle and not the joint or disc itself. While Botox can lead to temporary changes in muscle function, which might alter the mechanics of your jaw temporarily, it is unlikely to directly cause a disc displacement.

The heaviness and fatigue you are experiencing could be due to the reduced strength of the masseter muscle after Botox, which might make chewing more effortful. This muscle weakness could potentially contribute to altered jaw dynamics, but it is not a direct cause of disc slippage. It's important to discuss these symptoms with your healthcare provider, preferably someone experienced with TMJ disorders, to explore all potential causes and ensure you receive appropriate treatment.

Additionally, receiving Botox from a qualified professional who understands the anatomy and complexities of TMJ disorders is crucial. Consider consulting with a specialist, such as a dentist with expertise in TMJ or a maxillofacial specialist, to assess your symptoms and treatment options.
