Bruxism (Teeth Grinding)

Teeth grinding (bruxism) is a condition that occurs when an individual, often unconsciously, clenches, presses, or grinds their teeth, especially during sleep. This condition, which can be observed at night or during the day, can arise due to a series of factors such as stress, anxiety, sleep disorders, irregular eating habits, and genetic predisposition. Bruxism, which is quite common in society, can lead to serious problems such as tooth wear, sensitivity, fractured fillings, jaw muscle pain, headaches, and temporomandibular joint (TMJ) problems when it continues for a long time.

Although most people don't realize they grind their teeth (as it often happens at night), its effects are felt during the day and can negatively impact quality of life. With early diagnosis and appropriate treatment methods, it is possible to prevent the damage caused by bruxism and reduce complaints. Orthodontic Specialist Dentist Emin Serhat Arıkan, who serves his patients in his clinic in Adana, explained the causes, symptoms, and treatment methods of teeth grinding (bruxism).

What is Teeth Grinding (Bruxism)?

Teeth grinding (bruxism) is a muscle-jaw dysfunction that occurs when a person involuntarily clenches, presses, or grinds their teeth. Although mostly observed during sleep, it can also occur while awake during the day. Bruxism is generally associated with causes such as stress, anxiety, sleep disorders, malocclusion, and genetic predisposition. If it continues for a long time, it can lead to tooth wear and fractures, tooth sensitivity, jaw muscle pain, headaches, and temporomandibular joint (TMJ) problems. Most people are unaware that they grind their teeth; therefore, early diagnosis and appropriate treatment are crucial to prevent possible permanent damage.

What are the Symptoms of Teeth Grinding (Bruxism)?

Teeth grinding (bruxism) is a condition that is difficult for a person to notice, as it mostly occurs during sleep. However, some oral, jaw, and general body symptoms that manifest over time can indicate the presence of bruxism. Since the presence of these symptoms may indicate that bruxism is progressing, early evaluation by a dentist is essential.   

• One of the common symptoms is wear, fractures, loosening, cracks on tooth surfaces, and resulting sensitivity.
• Pain, stiffness, and fatigue may occur in the jaw muscles, especially in the early hours of the day, due to constant pressure.
• Head and neck pains concentrated in the temples and forehead, particularly noticeable in the mornings, as well as migraine attacks, can be felt due to bruxism.   
• Due to the jaw joint's proximity to the ear, pain, a feeling of fullness, or ringing in the ears may also accompany it.
• The sound of teeth grinding during sleep is often noticed not by the person themselves but by those sleeping with them.
• In advanced cases, limited jaw opening and closing movements, clicking or rubbing sounds from the joint, and difficulty opening the mouth may be experienced.
• Bruxism can negatively affect sleep quality, leading to lethargy, fatigue, and concentration problems during the day.

What are the Causes of Teeth Grinding (Bruxism)?

Teeth grinding (bruxism) does not arise from a single reason. It is typically a multifaceted condition resulting from the combination of psychological, physiological, and neurological factors. While bruxism can be observed in all age groups, it is more common in children and young adults. There is no significant difference in prevalence between genders. Often, several of these factors act together to cause teeth grinding. Therefore, correctly identifying the underlying causes is crucial for establishing an effective and lasting treatment plan. Common causes can be listed as follows:

• One of the most critical triggers is stress and anxiety. Intense pressure, emotional tension, and anxiety experienced in daily life can lead to involuntary clenching of the jaw muscles, especially during sleep.
• Factors affecting sleep patterns are also closely related to bruxism. Sleep apnea, insomnia, frequent waking, and irregular sleep habits are among the important factors that increase the risk of teeth grinding.
• Problems related to oral and jaw structure can also play a role in the development of bruxism. Misalignment of teeth, malocclusion, and temporomandibular joint (TMJ) disorders can cause excessive strain on the chewing muscles, paving the way for teeth grinding.
• Genetic predisposition is also a notable factor. Individuals with a family history of bruxism are more likely to experience this condition.
• Certain medications and stimulant substances can also exacerbate bruxism. Especially antidepressants, excessive caffeine consumption, alcohol, smoking, and some substances can affect the nervous system and intensify teeth grinding behavior.

How is Bruxism (Teeth Grinding) Treated?

In the treatment of bruxism (teeth grinding), early diagnosis, accurate cause analysis, and patient compliance with treatment are crucial. By using the right methods together, both complaints can be reduced and dental and jaw health can be protected in the long term.

Treatment is Planned Individually: The aim of bruxism treatment is to reduce the excessive load on the teeth and jaw joint, control pain and muscle tension, and prevent long-term permanent damage. Therefore, treatment is not one-sided; it is planned with a personalized and multidisciplinary approach. The severity, duration, and underlying causes of bruxism are decisive in the treatment process.

Splints (Night guards): In dental practices, splints can be used to protect the teeth and jaw joint. Although these splints do not completely eliminate bruxism, they help prevent wear on the teeth and damage to joint tissues. They improve the person's sleep quality, extend the lifespan of the teeth, and prevent potential diseases in the jaw joint. They are custom-made, and patients can use these splints for a very long time. It is a highly protective treatment and non-invasive. Splints are the first treatment option that comes to mind for jaw joint problems.

Botulinum Toxin (Botox): Botox reduces the excessive contraction of chewing muscles, controlling pain and clenching intensity. Good results can be achieved only when applied in appropriate cases under the supervision of a physician. It relaxes the chewing muscles and prevents acute discomfort.

Psychological Counseling: Considering the psychological and neurological dimensions of bruxism, supportive practices aimed at stress and anxiety management and improving sleep patterns are among the fundamental elements of the treatment process. Psychological counseling, relaxation techniques, behavioral therapies, and regulation of sleep hygiene help reduce symptoms. In the presence of co-existing sleep disorders like sleep apnea, evaluation by a sleep medicine specialist may be necessary.

Restorative Treatments Can Be Applied: If problems related to oral and jaw structure are present, restorative treatments such as completing missing teeth, correcting malocclusion, and treating advanced tooth wear can be applied. In some cases, muscle relaxants or short-term medication treatments may be preferred as supportive measures. However, medications usually do not provide a permanent solution on their own. On the other hand, if an underlying systemic disease such as reflux is detected, treating this condition can help control bruxism.
