About Bruxism (Teeth Grinding)
Bruxism is believed to be influenced by neurotransmitters in the central nervous system. The cause of bruxism is unknown.
It may have physical, psychological, or genetic risk factors including:
- Stress: Studies have shown that individuals at high risk for bruxism are those under daily stress. Anger and frustration may also be risk factors.
- Psychological factors like aggressive personality type are often mentioned as higher chances of bruxism.
- Smoking and use of alcohol, recreational drugs, caffeinated beverages may contribute to bruxism.
- Genetics: Sleep bruxisim may run in families.
- Medical Conditions: Bruxism has been associated with medical conditions, including Parkinson’s Disease, dementia, epilepsy, sleep apnea, and attention-deficit/hyperactivity disorder (ADHD).
In conclusion, bruxism can have multiple causes and risk factors. Understanding both the physical and psychological aspects of bruxism may be important for effective management.
Common symptoms of bruxism include:
- Teeth grinding or clenching
- Teeth that are flattened or chipped due to the pressure exerted during bruxism. The enamel may be worn on the teeth.
- Tooth pain.
- Loose teeth: Teeth may become loose or unstable due to the excessive grinding or clenching forces.
- Jaw soreness.
- Jaw or face pain that may be described as an earache.
- Sores on the inside of the cheek.
- Disrupted sleep.
As bruxism progresses or becomes more severe, other symptoms may also occur. These include:
- Malocclusions: Bruxism can lead to misalignment of the teeth, resulting in malocclusions. This can cause facial asymmetry, inadequate lip closure, mouth breathing, and anterior (front) and posterior (back) crossbite.
- Joint pain and pathology: Bruxism may be associated with pain in the temporomandibular joint (TMJ).
It is important to note that individuals with bruxism during sleep may not be aware that they are clenching or grinding their teeth. However, people who sleep near them may notice clicking, popping, or grinding noises when they move their jaw. Additionally, sleep bruxism can cause facial pain, jaw pain and stiffness, dull headaches, sensitive or broken teeth, worn teeth, broken or loose fillings, and even referred pain such as ear pain.
To diagnose bruxism, several examinations, tests, and procedures are commonly performed:
Dental examination: A dentist can diagnose bruxism by collecting symptom information and performing a dental examination.
- The dentist may ask if others have observed your teeth grinding. They may ask about your symptoms after awakening; for example, if your jaw, teeth, or gums feel sore or if you have pain in your jaw, ear, or head. They may also ask if you notice yourself clenching your teeth during the day.
- During this examination, the dentist may look for signs such as worn tooth enamel, flattened, fractured, or chipped teeth, loose or damaged crowns and fillings, and enlarged jaw muscles.
Depending on initial findings or individual factors, additional examinations, tests, or procedures may include:
- Psychological testing: In some cases, psychological testing may be performed to assess anxiety levels in patients with bruxism. This can help determine if there is a relationship between anxiety and bruxism.
- Polysomnographic examination: If necessary, a polysomnographic examination may be conducted to monitor sleep patterns and detect any abnormal muscle activity during sleep. This test involves attaching electrodes to various parts of the body to measure brain waves, muscle activity, heart rate, and breathing patterns.
- Genotyping: In certain research studies or specialized cases, genotyping may be performed to analyze specific genetic markers associated with bruxism.
It's important to note that while these examinations and tests can help diagnose and determine the severity of bruxism, the information obtained from parents or caregivers is also crucial. Parental observations play a significant role in diagnosing bruxism in children.
The goals of treatment for bruxism are to reduce physical, muscular, and psychological tension. To achieve these goals, various treatment options can be used:
- Splints or mouth guards: A dentist may recommend using a device fitted for your mouth to keep teeth separated to avoid damage caused by clenching the jaw and grinding teeth. The splits may be worn at night or during the day, depending on the type of bruxism.
- Medications: Medications can be prescribed to help manage bruxism. While there is no specific medication for treating bruxism, the healthcare professional may recommend certain types of medications to address symptoms such as muscle tension and anxiety. These medications may include muscle relaxants, anti-anxiety medications, and antidepressants.
- Muscle relaxants can help relax the jaw muscles and reduce grinding or clenching.
- Anti-anxiety medications and antidepressants can help manage stress and anxiety that may contribute to bruxism.
- Therapies: Different therapies can be beneficial in treating bruxism by addressing underlying causes or providing symptom relief. Some commonly recommended therapies include:
- Physical therapy: Physical therapy can help relieve muscle tension and improve jaw function through exercises, stretches, and manual techniques.
- Cognitive-behavioral therapy (CBT): CBT is a type of talk therapy that focuses on identifying and changing negative thought patterns and behaviors. It can help individuals manage stress, anxiety, and other emotional factors that contribute to bruxism.
- Biofeedback: Biofeedback involves using sensors to monitor muscle activity in the jaw. By providing real-time feedback on muscle tension levels, individuals can learn to recognize and control their clenching or grinding habits.
- Acupuncture: Acupuncture involves the insertion of thin needles into specific points on the body. It has been shown to reduce muscle activity in the jaw and promote relaxation.
- Therapeutic procedures:
- Dental correction: The dentist may adjust or reshape your teeth to correct the alignment of teeth or repair the biting surfaces of teeth so you will be able to chew properly.
Health behavior changes: Making certain lifestyle changes can also contribute to managing bruxism:
- Stress management techniques: Since stress is a common trigger for bruxism, finding effective stress management techniques such as exercise, relaxation exercises (e.g., deep breathing), and engaging in activities that promote relaxation (e.g., yoga) can help reduce teeth grinding or clenching.
- Avoiding stimulating substances: Avoiding or reducing consumption of substances like caffeine, tobacco, alcohol, or recreational drugs that may contribute to bruxism.
- Improving sleep hygiene: Maintaining a consistent sleep schedule, creating a relaxing bedtime routine, and ensuring a comfortable sleep environment can promote better sleep quality and potentially reduce bruxism episodes.
It's important to note that treatment approaches may vary depending on individual circumstances and severity of symptoms. A multidisciplinary approach involving healthcare professionals such as dentists, physical therapists, psychologists, and physicians may be necessary for comprehensive management of bruxism.
Complications of bruxism include:
- Irregularities in the alignment and structure of the teeth and gums.
- Pulp hypersensitivity: Bruxism can lead to increased sensitivity of the tooth pulp, which is the innermost part of the tooth containing nerves and blood vessels.
- Dental mobility: Teeth may become loose or unstable due to the excessive grinding or clenching forces.
- Fractures in teeth or restorations: The excessive pressure exerted during bruxism can cause cracks or fractures in teeth or dental restorations like fillings or crowns.
- Tooth surface loss: This is one of the most common findings in bruxism. It refers to the gradual wearing down of the tooth surfaces due to grinding or clenching.
- Pain: Bruxism can cause pain in the jaw, face, and even headaches.
- Temporomandibular disorders (TMD): TMD is a condition that affects the jaw joint and muscles involved in jaw movement. Bruxism has been associated with TMD, which can cause additional symptoms such as joint pain, muscle contracture, joint noises, and joint remodeling.
It's important to note that each person's experience with bruxism can differ. If you suspect you have bruxism or are experiencing related complications, it's best to consult a healthcare professional who can provide personalized advice and recommend appropriate treatment options.
