TMD treatment in Cologne – symptoms, diagnostics & splint

In Cologne, JUST KFO – Dr. Steinmaier & Kollegen (Hauptstraße 50, Köln) specializes in the treatment of TMD (temporomandibular disorder) and jaw joint pain. The team of specialists in orthodontics analyzes jaw joint and muscle complaints using digital functional and jaw joint measurement and fabricates individual occlusal splints in the practice’s own in-house master dental laboratory. Common reasons for consultation include jaw popping, jaw or facial pain, teeth grinding (bruxism), tension, and restricted mouth opening. The practice has published five peer-reviewed articles on the diagnosis and treatment of temporomandibular disorders — in the Journal of Aligner Orthodontics (2018, 2019) and in Informationen aus Orthodontie & Kieferorthopädie (2020); they are publicly accessible via ORCID 0000-0002-2054-8992 . You can book an initial consultation with functional analysis online.

If your jaw pops and pain occurs when chewing, yawning, or opening your mouth, an orthodontic practice specializing in TMD is a suitable first point of contact. At JUST KFO – Dr. Steinmaier & Kollegen (Hauptstraße 50, Köln), specialists in orthodontics examine the temporomandibular joints, jaw muscles, and bite with a clinical functional analysis during the initial appointment; depending on the findings, digital jaw joint measurement and imaging follow. You do not need a referral; please bring any existing records with you. An oral surgery practice or university clinic is mainly relevant if a surgical procedure needs to be considered, for example after an accident. If the symptoms persist for weeks or recur, have the cause examined – our TMD self-test.

Morning jaw or head pain, tense jaw muscles, and worn teeth can indicate nighttime grinding or clenching (bruxism). Whether a splint is appropriate and which type is determined by examination: A simple night guard primarily protects the teeth. If there are additional symptoms affecting the temporomandibular joint or muscles, we fabricate an individually measured occlusal splint in our in-house master dental laboratory based on the functional analysis. Relaxation exercises help as supportive measures, and physical therapy is recommended for severe tension. If snoring or breathing interruptions occur as well, we also consider a mandibular advancement device.

TMD stands for temporomandibular disorder (often called TMJ) – a dysfunction in the interaction between the temporomandibular joints, chewing muscles, and teeth. Typical signs include jaw pain, clicking or grinding in the joint, tension extending to the neck and temples, and teeth grinding; chewing, speaking, and mouth opening are frequently restricted. Possible causes include misaligned teeth, stress, muscle tension, or injuries. Treatment depends on the cause and may include physical therapy, relaxation exercises, pain management, and, if needed, an occlusal splint or orthodontic correction. Behind the umbrella term TMD are around 37 different clinical conditions from four groups – temporomandibular joint, chewing muscles, headache, and adjacent structures – and accordingly, what someone experiences and what helps in an individual case varies considerably.

The complaints are varied and differ from person to person. Common signs:

• Pain in the temporomandibular joints, the chewing muscles or the face
• Headaches or migraine
• Teeth grinding or clenching (bruxism)
• Limited jaw movement, for example when opening or closing
• Popping or grating in the temporomandibular joint
• Tension in the neck and shoulders
• Ear pain or tinnitus
• Dizziness
• Dental problems such as wear, loosening or sensitivity

If TMD is suspected, an orthodontist specializing in TMD establishes the diagnosis. Many patients with TMD report neck pain in addition to jaw symptoms – that is why we always examine the jaw, head, and neck together.

For a first idea of whether your complaints fit a TMD, try our TMD self-test.

Treatment depends on the diagnosis and the complaints. Possible components:

• Orthodontics: if misaligned teeth are the underlying cause, we consider whether correcting tooth and jaw position is appropriate after splint therapy
• Exercises and physical therapy: relax the chewing muscles and improve mobility
• Pain management: medication temporarily eases pain and muscle tension
• Behavioral changes: reducing stress, adjusting diet or sleeping position
• Occlusal splint: reduces the pressure on the temporomandibular joints
• Surgery: only in rare cases, for example after severe injuries or with tumors

Which combination makes sense depends on the diagnosis – functional analysis is part of every treatment plan at our practice.

We always begin with reversible measures: Guidelines recommend starting TMD treatment with reversible methods such as bite splints and occlusal splints, along with physical therapy, before considering invasive interventions. The bite splint is by far the most common treatment device; we always combine it with counseling and self-guided exercises, because studies show this approach works better than the splint alone. In a review of approximately 500 patients, targeted exercise therapy and bite splints performed about equally well in pain relief.4 How well a splint works varies from case to case: In a systematic review of masticatory muscle pain, symptoms disappeared completely in 17 to 59 percent of those treated with a relaxation splint, while 13 to 26 percent experienced no improvement.5

When improvement occurs varies from case to case: some patients notice relief in the first few weeks with the splint, while for others it takes longer for the muscles and joint to adjust to the new position. If no improvement occurs, the splint is readjusted or the diagnosis is expanded.

Some symptoms improve even without treatment; if they persist or return, a professional diagnosis is needed to ensure the treatment matches the cause. You can relieve symptoms yourself by: not overloading the jaw, reducing stress, practicing relaxation exercises, eating a healthy diet, and getting enough sleep. An early evaluation helps identify the cause and tailor treatment accordingly. For mild symptoms, the situation often improves through education and consistent self-care exercises; if pain persists for more than about six weeks, you should have the cause evaluated.

There is no fixed healing time – it depends on the cause, the severity and your individual symptoms. The goal is to reduce the symptoms and slow further progression. Often the symptoms improve after a few weeks to months; if the condition is chronic, it takes longer. Regular check-ups are important so that the treatment can be adjusted if needed. Splint therapy is usually planned for three to six months, and after about six weeks we review together whether the symptoms are moving in the right direction.

Yes, TMD can be painful. Pain in the jaw, head, face, and ears is common — often intensified by chewing, teeth grinding, or pressure on the jaw. Muscle tension in the jaw and neck area is frequent, sometimes accompanied by tooth discomfort. If you experience persistent jaw, head, or facial pain, you should have the cause evaluated — an early evaluation helps identify the cause and tailor treatment accordingly. Not every case of TMD is painful: jaw popping without pain or functional impairment is significantly more common than the painful form, which affects about ten percent of adults in Germany.

TMD usually has multiple causes — both physical and psychological. Stress, anxiety, or depressive strain can trigger or worsen it, because tension in the jaw and neck area overloads the masticatory muscles. However, it is not a purely psychological disorder: Misaligned teeth, trauma, or other physical factors also play a role. A sensible approach is therefore treatment that addresses both aspects — for example, supplemented with relaxation techniques, meditation, yoga, or psychotherapy. Because stress and tension contribute in many cases, we also assess how much the pain affects your daily life before treatment, for example on a scale from 0 to 10.

Left untreated, symptoms can worsen over time. Pain in the jaw and head area can become chronic and radiate to the neck, back, and shoulders. Jaw mobility can deteriorate (problems with chewing, speaking, opening the mouth), and teeth can wear down or loosen due to clenching and grinding. Ear ringing, sleep disturbances, and psychological stress are also possible; where nighttime snoring or breathing interruptions occur, we additionally evaluate mandibular advancement devices for sleep apnea. A timely evaluation helps properly assess the symptoms. Some symptoms improve even without treatment — in follow-up studies, however, about a quarter of affected individuals remained unchanged or in need of treatment after two and a half years, which is why we do not simply wait and see, but check after about six weeks.

If medically necessary, statutory health insurance covers part of TMD treatment – such as physical therapy with appropriate prescription. How much depends on the type and severity of the condition and your plan; functional analysis – both clinical and instrumental – is not covered by statutory insurance and is billed according to the fee schedule for dentists. At our practice, we work with a DMD bite splint based on digital jaw joint measurement – it is a private service and costs approximately 1,500 to 3,000 euros. Private insurance companies have their own terms. Clarify the scope with your insurance before starting treatment and obtain cost approval if needed – only your insurance company can give you binding information.

The cost depends on the type and severity of the condition, the treatment method and its duration. In our practice, conservative therapy is the main focus: its core element is the DMD bite splint based on a digital measurement of the temporomandibular joint – it costs approximately 1,500 to 3,000 Euro. Depending on the findings, functional diagnostics and accompanying physical therapy may be added. We set out the exact scope in advance in a transparent cost plan; regarding coverage, please check with your health insurance before treatment begins.

Any dentist may treat TMD. However, specialists and orthodontists have additional training and more experience in diagnosing and treating temporomandibular joint disorders — as well as appropriate equipment such as magnetic field-based DMD measurement or DVT. If TMD is suspected, it is therefore advisable to consult an experienced orthodontist who can perform a targeted examination and develop an individually tailored treatment. The German recommendations for TMD treatment are jointly supported by six professional societies — from functional diagnostics to orthodontics to physical therapy — and precisely this collaboration is what TMD treatment requires.

TMD is best diagnosed by an experienced orthodontist or TMD specialist. During the initial appointment, we examine the temporomandibular joint, masticatory muscles, and teeth using a clinical functional analysis. Depending on the findings, a separate appointment may follow for magnetic field-based measurement of the jaw joint and imaging: a cone-beam CT scan if bone changes are suspected, or an MRI to assess the articular disc. Because the symptoms are complex and often difficult to categorize, this experience is important—it enables an accurate diagnosis and individually tailored treatment. Progress is monitored regularly and adjusted as needed. The foundation is a standardized clinical examination based on internationally agreed criteria, which identifies the most common painful forms with over 85 percent accuracy; for example, a mouth opening of less than 40 millimeters is considered restricted.

Some exercises can relax the chewing muscles and improve jaw mobility:

• Stretching: slowly open and close your mouth while gently pressing your hand against the lower jaw; or open your mouth and tilt your head back slightly.
• Loosening: let the lower jaw hang loose and move it slowly to the right/left and up/down.
• Tongue: press the tongue against the palate and slowly draw it back.
• Relaxation: yoga, progressive muscle relaxation or breathing exercises release tension.

Not every exercise is right for everyone – have their suitability checked in advance with your doctor or physical therapist. In studies, coordination exercises for lower jaw movement in particular have proven useful – usually at least three times a day over one to three months.

The exact causes have not been conclusively researched; usually several factors act together:

• Stress: increases muscle tension in the jaw area
• Misaligned teeth: an unfavorable bite can be a contributing factor
• Grinding/clenching: places lasting strain on the chewing muscles and the temporomandibular joint
• Injuries/trauma to the temporomandibular joint or the chewing muscles
• Arthritis and other inflammatory joint diseases

Because the causes differ from person to person, an accurate diagnosis is the basis of treatment. A temporomandibular disorder (TMD) almost never has a single cause: teeth grinding and clenching play a major role – depending on the measurement method, roughly one in four to five adults grinds their teeth at night -, and stress, sleep problems and, in individual cases, misaligned teeth such as a one-sided crossbite are added to this.

A simple night guard primarily protects the teeth from nighttime grinding.2 A therapeutic functional splint for TMD goes further: It is custom-made following a functional analysis, relieves the temporomandibular joints, relaxes the masticatory muscles, and guides the lower jaw into a favorable position. It addresses function, not just tooth protection – whether tooth and jaw position is actually the cause in an individual case is determined only through functional diagnostics.

Between the condyle and the articular fossa of the temporomandibular joint lies a small cartilaginous disc, the articular disc. In disc displacement, this disc has slipped out of its normal position, usually forward. Orthodontists distinguish two forms: In disc displacement with reduction , the disc springs back into place when the mouth opens – this is the typical clicking. In disc displacement without reduction , it remains in front of the condyle; the mouth can then often only be opened to a limited extent, sometimes with pain.

Clues are provided by examination of jaw movement and digital joint measurement; in unclear cases, an MRI scan shows the position of the articular disc. Treatment depends on the findings and may include a splint, physical therapy, and targeted exercises. Popping without pain or restricted movement does not necessarily require treatment in every case—but it should be evaluated if it appears for the first time or changes. Suitable exercises can be found in our article on jaw relaxation exercises.

Costen syndrome is an older term for symptoms originating from the temporomandibular joint and manifesting at the ear: ear pain, tinnitus, a feeling of pressure, or dizziness without any identifiable cause in the ear itself. ENT physician James B. Costen described this connection in 1934. Today, these symptoms are grouped under the term temporomandibular disorder (TMD); the name Costen syndrome still appears in older medical reports and referrals. Those who find no cause for ear symptoms at the ENT specialist are therefore often in the right place with an orthodontist.
