JAW & BITE TREATMENT

TMJ & Occlusal Bite Problems

The temporomandibular joint - the TMJ - is the most frequently used joint in the human body. It connects the lower jaw to the skull on both sides of the head and is responsible for every movement involved in speaking, chewing, and opening or closing the mouth. When something disrupts its function, the effects are felt far beyond the jaw.

At Vilafortuny, TMJ dysfunction and occlusal bite disorders are assessed and treated by clinicians trained at the Kois Center - one of the most respected post-graduate dental institutions in the world, internationally recognised for its evidence-based approach to occlusion, bite analysis, and restorative care. Very few dental clinics in Dubai offer this level of specialized training.

What Is TMJ Dysfunction?

TMJ dysfunction occurs when the joint, the surrounding muscles, or the disc that cushions the joint are not working in harmony. This can stem from a misaligned bite, teeth grinding, jaw injury, arthritis, chronic stress, or disc displacement - and often a combination of these factors.

Because the jaw is part of a connected system of muscles, joints, and nerves that extends into the head, neck, and shoulders, TMJ dysfunction frequently produces symptoms that patients - and many clinicians - do not immediately associate with a dental problem.

Signs & Symptoms to Look For

Jaw pain, stiffness, or tenderness - especially in the morning Clicking, popping, or grinding sounds when opening or closing the mouth Difficulty or discomfort when chewing, yawning, or speaking Frequent headaches or migraines, particularly around the temples Earache or a sensation of ringing in the ears (tinnitus) Neck, shoulder, or upper back tension and pain Teeth that feel sensitive, loose, or worn downA noticeable change in how your upper and lower teeth meet

If you recognise several of these symptoms, a comprehensive bite and jaw assessment at Vilafortuny is the right starting point - not a painkiller.

Occlusal Bite Problems

The occlusion is the relationship between your upper and lower teeth when the jaw is closed. Very few people have what would be considered a clinically perfect bite - and for most, minor irregularities cause no problems. But when the bite is significantly misaligned, or when teeth have shifted due to grinding, wear, missing teeth, or previous dental work, the consequences can be substantial.

An unstable bite places unequal pressure on individual teeth and joints, leading to accelerated wear, cracking, gum recession, and chronic muscular strain. The Kois approach to occlusal analysis at Vilafortuny identifies exactly where that instability originates - and treats it at the source.

The Kois Deprogrammer

One of the key diagnostic tools used at Vilafortuny is the Kois Deprogrammer - a precision device developed by the Kois Center that temporarily removes the influence of the existing bite on the jaw's muscular system. By doing so, it allows the clinician to identify the jaw's true natural resting position - independent of any compensations the muscles have developed over time.

Why this matters : Many patients have been grinding, clenching, or adapting to a misaligned bite for so long that their muscles have "learned" an incorrect position. The Kois Deprogrammer resets this, revealing the bite that treatment should be built around - not the one the patient has compensated for.

This approach ensures that any subsequent treatment - whether a nightguard, restorative work, or orthodontics - is planned against an accurate, stable baseline. It is the difference between managing symptoms and resolving them.

Treatment Options at Vilafortuny

TMJ and occlusal treatment is never one-size-fits-all. Following a thorough assessment, your clinician will recommend the most appropriate approach for your specific case - which may include one or more of the following:

  • Custom Nightguards & Occlusal Splints : Precision-fabricated appliances worn during sleep to protect teeth from grinding and clenching forces, relieve jaw muscle tension, and stabilise the joint. Unlike over-the-counter options, a custom-fitted nightguard from Vilafortuny is designed around the exact contours of your bite for both comfort and clinical effectiveness.
  • Kois Deprogrammer Therapy : A diagnostic and therapeutic device that deprograms the muscles influencing bite position, allowing the jaw to settle into its natural resting position. Used to guide accurate treatment planning for complex occlusal cases.
  • Bite Equilibration: Minor reshaping of tooth surfaces to eliminate high spots in the bite that cause uneven force distribution. A conservative, highly targeted approach for bite-related muscle strain and tooth wear.
  • Stress & Lifestyle Management Guidance : Stress is one of the primary drivers of bruxism and jaw clenching. Your clinician will discuss practical strategies - including jaw exercise protocols and postural habits - that support treatment outcomes and reduce recurrence.
  • Restorative & Orthodontic Treatment : Where bite instability stems from missing teeth, worn enamel, or misalignment, longer-term restorative or orthodontic treatment may be recommended in conjunction with immediate symptom relief. All restorative planning at Vilafortuny follows the Kois framework for occlusal stability.
  • Referral to TMJ Specialist or Oral Surgeon: In cases requiring arthrocentesis, arthroscopy, or joint reconstruction, Vilafortuny will coordinate a specialist referral and continue to manage your overall dental care in parallel.
Nightguards - What You Need to Know

A nightguard is not a cure for TMJ dysfunction - it is a protective measure and, in many cases, a first step. At Vilafortuny, we are clear with patients about what a nightguard does and does not do.

If you clench without grinding, a standard nightguard may not be the right solution - clenching is often bite-driven rather than habit-driven, and a proper functional assessment is needed first. Choosing the wrong appliance can, in some cases, worsen symptoms.

  • Custom-fitted is always preferable to boil-and-bite or over-the-counter options - for both effectiveness and long-term comfort.
  • Clean your nightguard daily with soap and water, and bring it to every routine check-up for inspection.
  • Expect to replace it every 12–18 months depending on grinding severity, or sooner if significant wear is visible.
  • A nightguard prescribed following a Kois Deprogrammer assessment is built on a verified bite position — not an estimated one.
Results
  • Reduction or elimination of jaw pain, headaches, and muscular tension.
  • Protection of teeth from further wear, cracking, and sensitivity.
  • Improved sleep quality - particularly for patients with bruxism.
  • A stable, accurately assessed bite as the foundation for any future dental treatment.
  • Long-term prevention of escalating damage to teeth, gums, and the joint itself.
Indications
  • Jaw pain, stiffness, clicking, or locking - with or without a known cause.
  • Chronic morning headaches or facial muscle soreness.
  • Visible tooth wear, flattening, or unexplained chipping.
  • A partner or family member noticing grinding sounds during sleep.
  • Earache or tinnitus with no identified ENT cause.
  • Neck and shoulder tension that persists despite physiotherapy.
  • Any planned restorative, orthodontic, or implant treatment — bite stability must be assessed before this work begins.
Recommendations Before Your Appointment
  • Keep a brief note of your symptoms - when they occur, what makes them better or worse, and how long you have been experiencing them.
  • Bring any previous X-rays, dental records, or imaging if available.
  • Avoid particularly hard or chewy foods in the days before your assessment if your jaw is currently inflamed.
  • Inform the clinic of any medications you are taking, including anti-inflammatory drugs or muscle relaxants.
After Your Appointment
  • Follow the specific aftercare guidance provided by your clinician - this will depend on the treatment chosen.
  • If a nightguard or splint has been fitted, wear it consistently from the first night - erratic use significantly reduces its effectiveness.
  • Attend all follow-up appointments - TMJ treatment requires monitoring and adjustment over time.
  • Report any new or worsening symptoms promptly rather than waiting for the next scheduled visit.

Frequently Asked Questions

How do I know if my headaches are caused by TMJ dysfunction?

TMJ-related headaches typically present around the temples, the sides of the head, or behind the eyes - and are often worst in the morning, following a night of clenching or grinding. They are frequently accompanied by jaw soreness, facial tension, or a feeling of tightness in the jaw muscles. If headaches persist despite normal neurological evaluation or do not respond to standard treatment, a dental bite assessment is a logical and often overlooked next step. At Vilafortuny, we assess the full occlusal picture to determine whether your jaw is contributing to your symptoms.

What is the difference between teeth grinding and jaw clenching?

Grinding (bruxism) involves lateral movement of the teeth against each other - it produces the audible sound that partners or family members often notice during sleep, and creates visible flat wear patterns on enamel. Clenching involves sustained vertical pressure with no movement - it is silent, often stress-driven, and produces muscular fatigue, headaches, and tooth sensitivity without the same wear patterns. Both are damaging, but the correct treatment differs. A proper functional assessment at Vilafortuny determines which is occurring - and why - before any appliance is prescribed.

What is the Kois Center and why does it matter for my treatment?

The Kois Center is a post-graduate dental institution in Seattle, Washington, widely regarded as one of the most rigorous and evidence-based programmes in the world for advanced dentistry, occlusion, and restorative care. Clinicians who complete the Kois curriculum - including Dr. Kathrin Trelles at Vilafortuny - are trained to assess the bite, the joints, the periodontium, and the structural integrity of the teeth as an integrated system, not as isolated problems. For TMJ and occlusal treatment specifically, this means your care is grounded in a full-system diagnosis rather than symptom management alone.

Will I need surgery for TMJ dysfunction?

The vast majority of TMJ cases are successfully managed without surgery. Conservative treatments - including occlusal splints, the Kois Deprogrammer, bite equilibration, and targeted lifestyle changes - resolve or significantly reduce symptoms for most patients. Surgery is reserved for structural joint problems that have not responded to conservative management, and is always the final rather than the first step. At Vilafortuny, we exhaust all conservative options thoroughly before considering or recommending a surgical referral.
