Understanding Bruxism and TMJ

Bruxism and TMJ are two conditions that are often confused with each other, even though they have different causes, symptoms, and treatments.

It's important to Understand the differences for Bruxism vs TMJ, to receive the proper diagnosis and treatment for these conditions.

The causes of Bruxism and TMJ can be quite different. Bruxism is often linked to stress and anxiety, this can lead to the involuntary grinding of the teeth. Other factors that can contribute to Bruxism include certain medications, alcohol and drug use, and sleep disorders.

Are Bruxism and TMJ Linked?

Bruxism and TMJ are often linked but they are two separate conditions. Bruxism, or teeth grinding and clenching, can contribute to TMJ disorders by putting excessive strain on the jaw muscles and joints. Over time, this can lead to inflammation, pain, and dysfunction of the temporomandibular joint, which connects the jawbone to the skull. TMJ disorders can cause or worsen Bruxism as the pain linked with TMJ can trigger teeth grinding and clenching. Both conditions can cause each other but it isn't always likely (thank god for that).

While Bruxism and TMJ are not always linked, it is important to address both conditions to ease symptoms and prevent further damage.

Treatment Options for Bruxism vs Treatment for TMJ

Botox treatment is not a permanent solution and lasts for around six months, yet Botox (botulinum toxin) treatment is a minimally invasive option that can be effective in reducing the symptoms of both Bruxism and TMJ. Botox works by weakening the muscles responsible for teeth grinding and clenching.

Botox's effects on Bruxism?

A small amount of Botox is directly injected into the masseter muscle, which is the muscle responsible for chewing. Botox can reduce the force of teeth grinding and clenching by decreasing the strength of this muscle, which can ease symptoms of Bruxism.

and how does Botox work for TMJ?

Botox is injected into the muscles surrounding the temporomandibular joint. This causes the muscles surrounding the joint to weaken. By weakening these muscles, Botox can reduce inflammation and ease pain associated with TMJ disorders. So you can relax again!

Botox is not recommended for everyone, and potential risks and side effects include pain, swelling, bruising, and changes in facial expressions. At DR Aesthetica 95% of TMJ/Bruxism Botox treatments are successful.

Botox has to be executed by a licensed and experienced medical professional. You can discuss the potential benefits of Botox with us, feel free to contact us today to talk to us about your TMJ or Bruxism struggles. We are all ears to hear about your struggles.
