Teeth clenching, or bruxism in medical terminology, is a common condition that many people experience without even realizing it. If you constantly grind or clench your teeth, this can lead to various complications such as jaw pain, headaches, and tooth damage.

But why does jaw pain occur? What are the symptoms of teeth clenching? Can neck pain cause teeth clenching? What role can an osteopathic approach play in addressing this problem?

What Is Teeth Clenching?

Known medically as bruxism, teeth clenching is a condition in which you clench or grind your teeth against each other. Also known as teeth clenching or teeth grinding, it is a common condition that can occur during the day or at night.

If you experience daytime teeth clenching, you may unconsciously clench or grind your teeth while awake without realizing it. In the case of nighttime teeth clenching, this movement disorder occurs during sleep.

People who clench and grind their teeth during sleep are generally more likely to experience other sleep disorders, such as snoring and breathing pauses known as sleep apnea. Some people do not realize that they have sleep bruxism until they experience dental or jaw problems as a result.

In some people, bruxism occurs frequently enough to cause complications such as jaw pain, headaches, tooth damage, and other problems. The sound of teeth grinding can also disturb the sleep of the person sharing the same bed.

What Causes Teeth Clenching? (An Osteopathic Perspective)

From an osteopathic perspective, teeth clenching and grinding are not simply problems that originate in the jaw muscles. Stress or tension in any part of the body can affect the jaw joint and contribute to teeth clenching.

The muscles, bones, and organs in our body are interconnected through the fascial connective tissue system. Therefore, a problem in the jaw joint may spread through the fascia as far as the lower back and cause pain.

While some symptoms are directly related to teeth clenching, others may result from accompanying musculoskeletal problems.

• In the osteopathic approach, one of the most important considerations is the balance of the autonomic nervous system. If your sympathetic nervous system is constantly active, you may benefit from perception and awareness training. The way we perceive events can increase the sensitivity of our nervous system, which may cause us to feel constantly stressed or anxious.
• During daytime teeth clenching (or when the jaw muscles contract involuntarily during sleep), the jaw muscles can become overactive, causing jaw and temple pain, headaches, stiffness in the back of the neck, and tooth sensitivity.
• Temporomandibular joint (TMJ) dysfunction resulting from impaired function of the jaw joint may cause a person to unconsciously try to stabilize their jaw. This can contribute to nighttime teeth clenching.
• Restricted movement of the vertebrae in the upper part of the neck can also affect the function of the jaw muscles. This is because the nerves controlling the jaw are connected with the nerves in the neck region. Therefore, people experiencing teeth clenching often have complaints such as neck stiffness, pain at the back of the neck, and headaches in addition to jaw pain.
• The hyoid bone is connected to the tongue, mandible, neck, and larynx. Restricted movement in this area can cause persistent tension in the jaw muscles.
• Restricted movement of the rib cage can also affect the tissues around the neck and jaw, placing additional stress on the temporomandibular joint (TMJ).
• If your diaphragm remains tense, this may stimulate the parasympathetic system, indirectly affect the vagus nerve, and make it more difficult for you to relax.
• Sleep problems such as sleep apnea, snoring, frequent awakenings, and poor sleep quality can increase teeth clenching.
• Cranial osteopathy evaluates the movement of certain bones in the skull and their coordination with one another. This approach can help identify and understand areas of tension around the jaw and head.
• Postural problems can also contribute to teeth clenching.

What Are the Symptoms of Teeth Clenching?

• Pain and fatigue in the jaw muscles, including getting tired quickly while chewing gum and having difficulty chewing hard foods.
• Waking up with a headache in the morning, with a pressing or tightening pain in the temples, forehead, and around the eyes.
• Clicking, popping, catching, or grinding sounds coming from the jaw joint.
• Difficulty fully opening the mouth, pain when opening the mouth, or the jaw shifting to one side while opening.
• The jaw and neck muscles work together. Therefore, teeth clenching is often accompanied by pain at the back of the neck, neck stiffness, and difficulty turning the head.
• Shoulder stiffness, pain between the shoulder blades, and a constant feeling of muscle tension.
• Tooth sensitivity, flattening, and cracks in the teeth.
• During nighttime teeth clenching, a person may unconsciously bite their cheek, lip, or sometimes tongue.
• Tooth marks appearing along the sides of the tongue.
• Ear pain is also common. Some people may experience pressure, ringing, buzzing, humming, fullness, or blockage in the ears.
• A feeling of tension or pressure in the cheeks, temples, or around the cheekbones.
• Pain around the eyes, eyebrows, and forehead.
• Frequent waking, waking without feeling rested, and feeling tired in the morning.
• Some people may also experience snoring or sleep apnea. In such cases, evaluation by a sleep medicine specialist is important.
• The person’s spouse, partner, or someone who sleeps in the same room is often the first to notice the problem.

What Helps? (Osteopathic Approaches)

From an osteopathic perspective, the primary goal in treating teeth clenching is not simply to reduce symptoms, but to identify the underlying causes and address the temporomandibular joint (TMJ), muscles, nervous system, and lifestyle as a whole.

At the same time, current scientific evidence suggests that teeth clenching treatment is more successful when managed through a multidisciplinary approach involving a dentist, physiotherapist, and, when necessary, a psychologist and physicians specializing in sleep disorders.

The first goal of osteopathic treatment is to assess movement restrictions in the temporomandibular joint and surrounding structures and support function through appropriate manual techniques.

Jaw exercises are one of the most important steps in physiotherapy. Controlled mouth opening, placing the tongue on the roof of the mouth, and isometric jaw exercises are examples of these practices.

Most people who experience teeth clenching also clench their teeth unconsciously during the day. Adopting the correct resting position can help reduce unnecessary muscle load throughout the day.

In the correct resting position:

• the lips are closed,
• the teeth are not touching each other,
• the tongue rests against the front part of the roof of the mouth, and
• the jaw muscles are relaxed.

People who experience teeth clenching often have a forward head posture, tension in the neck muscles, and shoulders positioned forward or elevated. Exercises that strengthen the neck muscles, improve shoulder blade stability, stretch the chest muscles, and improve mobility in the back can also be used to help correct posture.

People who breathe superficially may have increased sympathetic nervous system activity, which can generally lead to increased muscle tension. Therefore, techniques such as diaphragmatic breathing, breathing exercises, and controlled exhalation can be incorporated into the treatment program.

Stress is one of the most important triggers of teeth clenching. Awareness training, relaxation exercises, brisk walking, regular physical activity, breathing exercises, and properly training our minds can make it easier to identify the underlying source of the problem.

Frequently Asked Questions

How Can Teeth Clenching Be Relieved?

Because teeth clenching (bruxism) does not have a single cause, its treatment is also individualized. The underlying cause should first be identified. Treatment may include a night guard, improving sleep quality, relaxing the chewing muscles, and physiotherapy focused on the area around the temporomandibular joint (TMJ). Reducing excessive tension in the neck and jaw muscles can also help relieve symptoms in many people.

What Can Teeth Clenching Be a Sign Of?

It is generally associated with sleep disorders, jaw joint problems, side effects of certain medications, and breathing problems during sleep.

How Can You Tell If You Are Clenching Your Teeth?

When you wake up in the morning, you may experience jaw pain, headaches in the temples, tooth sensitivity, or notice worn or cracked teeth. Symptoms such as ear pain or tooth marks on the inside of the cheek or on the tongue may also indicate teeth clenching.

What Happens If Teeth Clenching Is Not Treated?

It can cause tooth enamel wear, cracked teeth, pain and restricted movement in the jaw joint, and stiffness in the chewing muscles. Early evaluation can help prevent these problems from progressing.

What Causes Teeth Clenching from a Psychological Perspective?

Stress that is suppressed during the day may manifest as involuntary contraction of the jaw muscles, particularly during sleep. However, not every case of teeth clenching has a psychological cause. Biological factors and sleep-related factors also play an important role in the development of teeth clenching.

Why Do People Clench Their Teeth While Sleeping at Night?

Nighttime teeth clenching is involuntary muscle activity that occurs during sleep. Poor sleep quality, snoring, breathing problems, and certain neurological mechanisms can trigger this condition. Therefore, it is important to consider not only the teeth but also sleep patterns and overall health.

Which Doctor Should You See for Teeth Clenching?

You can consult a dentist for an initial evaluation. When necessary, you may be referred to an oral and maxillofacial surgeon, an ear, nose, and throat (ENT) specialist, a neurologist, or a physician specializing in sleep disorders. If you experience pain or restricted movement in the jaw joint and surrounding muscles, physiotherapy can also be an important part of treatment following a medical evaluation.
