What Is Bruxism?

Bruxism is the tendency of certain people to clench their teeth tightly or grind them by sliding or rubbing their back teeth back and forth against each other. This habit can occur both during the day and at night; depending on the case, it is referred to as daytime or nighttime bruxism. Nocturnal bruxism is usually more difficult to control. We do not know the exact causes of bruxism, but we do know its risk factors. One of the main risk factors is stress, especially in daytime bruxism.

What is ATM?

The temporomandibular joint, known as the TMJ, consists of the bones, muscles, ligaments, and joint capsule that allow the mouth to open and close. They are located on both sides of the head, and both TMJs work simultaneously when chewing, speaking, or swallowing. The TMJ also controls the side-to-side and forward movements of the jaw.

Each TMJ has a meniscus between the head of the jaw (condyle) and the articular fossa. This meniscus acts like a disc that, by serving as a cushion, absorbs the occlusal forces of the jaw and allows the jaw to open wide thanks to a movement that is first circular and then translational. Any disruption in this complex system of muscles, ligaments, and menisci can cause TMJ dysfunction and pain.

Orofacial pain can have various causes and is often related to the TMJ (temporomandibular joint) and the muscles, ligaments, and tendons associated with it.

Our Methodology

At Clínica Birbe, we begin by making an accurate diagnosis of the source of the problem, which will then guide us in determining the most appropriate treatment to follow. To do this, in addition to a thorough interview and physical examination, we often need a CT scan and/or an MRI.

We offer a first-line of conservative treatments and recommended measures; if these are not sufficient, we proceed with joint injections (arthrocentesis), minimally invasive surgery (arthroscopy), and, as a last resort and under certain conditions, open surgery. Initial conservative treatments include:

  • Eat soft foods
  • Avoid biting your nails and chewing gum
  • Apply heat to the painful areas
  • Relaxation techniques for managing jaw tension, such as biofeedback or meditation

Conservative treatments include various forms of physical therapy and the use of a pressure-relieving splint. Intra-articular injections, or arthrocentesis, serve two purposes: to flush inflammatory molecules from the joint and the synovial fluid, and to inject anti-inflammatory medication. We also aim to perform a hydraulic expansion of the joint to restore the space necessary for proper meniscus mobility.


In addition to visualizing and irrigating the joint, arthroscopy aims to secure the meniscus in its correct position with a pin.

Open surgery for osteoarthritis is rare. In cases of meniscus tears or ruptures. If there are joint conditions such as tumors, ankylosis, or fractures, each one requires a specific surgical treatment.

Finally, in cases of severe wear and tear and joint damage, it may be necessary to implant a TMJ prosthesis, similar to those used in the hip.

What are the symptoms of TMJ or bruxism?

Dolores

Pain in the face, jaw, ears, temples, and neck that often radiates to the head.

Limited Movement

Limited movement when opening the mouth or a locked jaw when closing it.

Stiffness

Stiffness in the jaw muscles due to prolonged muscle spasm

Malformation

A change in the way the teeth fit together due to the action of contracting muscles.

Chewing Problems

Difficulty or discomfort when chewing certain foods.

Spasms

Muscle spasms around the jaw that do not subside and are involuntary.

Frequently Asked Questions About TMJ & Bruxism

Bruxism is the involuntary habit of clenching or grinding one’s teeth, often while sleeping. It puts excessive strain on the masticatory muscles and the temporomandibular joint (TMJ), causing pain, tooth wear, headaches, and, sometimes, jaw clicking or locking. At Clínica Birbe in Barcelona, we take a comprehensive approach to treating bruxism.

The treatment combines a custom-made occlusal splint, stress management, physical therapy, occlusal adjustments, and, when appropriate, intramuscular injections of botulinum toxin. In cases of severe TMJ involvement, surgery may be considered. Each case is diagnosed through a functional examination and, if necessary, imaging tests such as an MRI.

In most patients, morning pain, headaches, and jaw tension improve significantly. The mouthguard prevents progressive tooth wear. The results are maintained as long as the patient adheres to the treatment (use of a splint, physical therapy, stress management) and attends regular follow-up appointments.

The price depends on the necessary tests, the type of splint, and the recommended complementary treatments. That’s why we tailor our approach to each individual case, providing a fixed quote after the first visit. We offer financing. An initial consultation is the best way to get some guidance with no obligation.

Dr. Joan Birbe: Treatment of TMJ Disorders and Bruxism Using the ABOMS Approach

Bruxism and TMJ disorders often go hand in hand and require a conservative approach before considering any surgical options. Dr. Birbe’s ABOMS certification ensures this step-by-step approach: a custom orthotic splint, habit control, physical therapy, and, occasionally, botulinum toxin injections into hypertonic muscles. Surgery is only considered when the rest of the treatment plan does not resolve the problem.

Why Get Treatment for Bruxism and TMJ at Clínica Birbe?

Bruxism wears down the teeth, the jaw joint, and the muscles. We approach it as a global problem, not just as a splint forced onto the patient.
• Functional diagnosis including muscle and joint examination, as well as imaging.
• Custom-made bite splints, fabricated using an intraoral scanner.
• Management of bruxism through occlusal adjustments and, if appropriate, botulinum toxin.
• Coordinate with the rheumatology unit when significant joint symptoms appear.
• Regular follow-up to prevent recurrence and protect dental restorations.
