What is bruxism and how does it affect us?

Bruxism is defined as the parafunctional activity of the jaw that consists of unconsciously clenching or grinding teeth. This habit, which can occur both during the day (daytime bruxism) and at night (nighttime bruxism), generates excessive tension in the masticatory muscles. The consequences can be varied and affect both health and facial aesthetics.

Common symptoms include headaches, neck pain, dental wear, tooth sensitivity, and muscle fatigue in the jaw. Aesthetically, chronic bruxism can lead to hypertrophy of the masseter muscles, resulting in a widening of the lower part of the face, giving it a more square appearance. At Santé Clínica Estética, our goal is to offer effective relief and a harmonious improvement of the facial contour.

Bruxism treatment with neuromodulators

At Santé Clínica Estética, the main treatment for bruxism is based on the application of neuromodulators. This substance temporarily relaxes the masseter muscles, which are primarily responsible for chewing force. By relaxing these muscles, pressure on the teeth and temporomandibular joints is reduced.

The application is an outpatient medical procedure, performed by our board-certified medical doctors. A small amount of neuromodulator is injected directly into the masseter muscles. This treatment is safe and effective, and its effects are progressively appreciated, offering lasting relief from bruxism symptoms. Results may vary individually.

Benefits of neuromodulator treatment

Bruxism treatment with neuromodulators offers multiple benefits, both functional and aesthetic. The reduction of masseter muscle activity significantly relieves the pain and tension associated with bruxism. This includes a decrease in headaches, neck pain, and jaw pain.

From an aesthetic point of view, the relaxation of the masseters can result in a reduction of their volume over time. This contributes to refining the facial contour, making the face acquire a more oval and slimmed shape. It is a subtle effect that complements facial harmonization, without altering natural expression. The duration of effects may vary individually.

The procedure at Santé Clínica Estética

At Santé, every treatment begins with a detailed medical consultation to evaluate your specific case. During this assessment, our doctors will examine your masseter muscles and facial structure. Your symptoms and expectations will be discussed to ensure an appropriate and safe treatment plan. The application of the neuromodulator is performed in the clinic and usually lasts about 15-30 minutes.

After the treatment, you can resume your daily activities immediately, although it is recommended to avoid massaging the treated area. Functional results, such as pain reduction, begin to be noticed within the first few days. The aesthetic effect of facial slimming develops gradually over the following weeks, as the muscle relaxes and reduces its volume. A follow-up review at two weeks is included at no additional cost.

Frequently asked questions

Is the treatment painful?

The application of neuromodulators is done with very fine needles, and most patients experience only mild and momentary discomfort. A topical anesthetic cream can be applied if necessary to maximize your comfort during the procedure.

How long will it take to see results?

The effects of muscle relaxation and pain relief usually begin to be noticed within a few days of application. The aesthetic effect of facial slimming is more gradual and is fully appreciated after 2-4 weeks, as the volume of the masseter muscle progressively decreases.

Are there any side effects?

Side effects are generally mild and temporary. They may include small bruises or swelling at the injection site, which disappear within a few days. In rare cases, there may be slight weakness when chewing very hard foods, which resolves spontaneously.
