Teeth Grinding

Bruxism: Causes, Symptoms & Treatment Options in Sussex, UK

6/1/2013

Dr. Bruno Silva

Bruxism, commonly referred to as teeth grinding or jaw clenching, is a condition characterized by the involuntary or habitual grinding of teeth and clenching of the jaw. This activity can occur during wakefulness (awake bruxism) or sleep (sleep bruxism). While occasional teeth grinding may not cause harm, persistent bruxism can lead to dental damage, jaw disorders, and other health complications.

The prevalence of bruxism varies, with studies indicating that approximately 8.6% of the general population experiences regular sleep bruxism . Awareness and early detection are crucial, as many individuals may not realize they grind their teeth until complications arise.

Types of Bruxism: Awake vs. Sleep

Bruxism manifests in two primary forms: awake bruxism and sleep bruxism.

Awake Bruxism

Awake bruxism involves conscious or semi-conscious clenching of the teeth and jaw during the day. It is often associated with emotional states such as stress, anxiety, or concentration. Individuals may notice themselves clenching their teeth during periods of intense focus or emotional distress.

Sleep Bruxism

Sleep bruxism occurs during sleep and is considered a sleep-related movement disorder. It is typically identified by partners who hear grinding noises or by dentists who observe signs of tooth wear. Sleep bruxism is more challenging to control due to its unconscious nature and may be linked to other sleep disorders, such as obstructive sleep apnea.

Recognizing the Bruxism Symptoms

Identifying bruxism early can prevent significant dental and health issues. Common symptoms include:

Dental Indicators: Flattened, fractured, chipped, or loose teeth; worn tooth enamel exposing deeper layers of the tooth.
Jaw and Facial Pain: Tight or fatigued jaw muscles; pain or soreness in the jaw, neck, or face; pain resembling an earache, though it's not a problem with your ear.
Headaches: Dull headaches starting in the temples; tension-type headaches.
Sleep Disruption: Sleep bruxism can lead to disrupted sleep for both the individual and their sleep partner due to grinding noises.

If you experience any of these symptoms, it's advisable to consult with a dental professional for evaluation and management.

Bruxism Causes and Risk Factors

The exact cause of bruxism is multifactorial and may include:

Psychological Factors: Stress, anxiety, anger, frustration, or tension can increase the risk of bruxism.
Personality Type: Individuals with aggressive, competitive, or hyperactive personalities may be more prone to bruxism.
Medications and Substances: Certain psychiatric medications, such as antidepressants, and substances like caffeine, alcohol, tobacco, or recreational drugs can contribute to bruxism.
Sleep Disorders: Conditions like obstructive sleep apnea are associated with increased risk of sleep bruxism.
Other Factors: Bruxism may be associated with other medical conditions such as Parkinson's disease, dementia, gastroesophageal reflux disorder (GERD), epilepsy, night terrors, or attention-deficit/hyperactivity disorder (ADHD).

Diagnosing Bruxism

Diagnosis of bruxism typically involves:

Dental Examination: Dentists look for signs of tooth wear, damage to dental restorations, and tenderness in jaw muscles.
Patient History: Discussion about symptoms, sleep habits, and lifestyle factors.
Sleep Studies: In cases where sleep bruxism is suspected, a polysomnographic study (sleep study) may be recommended to assess for bruxism episodes and rule out other sleep disorders.

Early diagnosis is essential to prevent further dental damage and to implement effective treatment strategies.

Potential Bruxism Complications

Untreated bruxism can lead to several complications:

Dental Damage: Excessive grinding can result in tooth fractures, loss of teeth, and damage to dental restorations such as crowns and fillings.
Temporomandibular Joint Disorders (TMD): Bruxism can cause or exacerbate TMD, leading to pain, clicking or popping sounds in the jaw, and difficulty opening or closing the mouth .
Chronic Pain: Persistent jaw, neck, or face pain; tension-type headaches.
Sleep Disruption: Sleep bruxism can lead to poor sleep quality, affecting overall health and well-being.

Addressing bruxism promptly can mitigate these risks and improve quality of life.

Bruxism Treatment Options

Managing bruxism effectively requires a multifaceted approach tailored to the individual's specific needs and the severity of their condition. Treatment strategies aim to alleviate symptoms, prevent dental damage, and address underlying causes.

Dental Interventions

Custom-Fitted Mouthguards and Splints: These are among the most common and effective treatments for bruxism. Worn during sleep, these devices act as a protective barrier between the upper and lower teeth, reducing the risk of tooth wear, fractures, and other damage. They also help in redistributing the biting forces, thereby alleviating strain on the jaw muscles.
Occlusal Adjustments: In cases where misaligned teeth contribute to bruxism, dental professionals may perform occlusal adjustments. This involves reshaping the biting surfaces of the teeth to achieve a more balanced bite, potentially reducing grinding and clenching tendencies.

Behavioral and Psychological Therapies

Stress Management Techniques: Since stress and anxiety are significant contributors to bruxism, incorporating stress-reduction strategies can be beneficial. Techniques such as mindfulness meditation, deep breathing exercises, and yoga can help in managing stress levels.
Cognitive Behavioral Therapy (CBT): CBT is a structured, goal-oriented therapy that helps individuals identify and modify negative thought patterns and behaviors. For bruxism patients, CBT can address the psychological factors contributing to teeth grinding, leading to long-term relief.

Pharmacological Treatments

Muscle Relaxants: In certain cases, short-term use of muscle relaxants may be prescribed to reduce jaw muscle tension during sleep, thereby decreasing the frequency and intensity of bruxism episodes. It's essential to use these medications under the supervision of a healthcare provider due to potential side effects.
Botulinum Toxin (Botox) Injections: For individuals with severe bruxism unresponsive to other treatments, Botox injections into the jaw muscles can be considered. Botox works by temporarily paralyzing the muscles responsible for grinding, thereby reducing the activity. Studies have shown that Botox can be effective in decreasing the frequency of bruxism episodes and alleviating associated pain.

Alternative Therapies

Physical Therapy: Targeted exercises and manual therapy can help in relieving muscle tension and improving jaw mobility. Physical therapists can also provide guidance on posture and ergonomics to reduce strain on the jaw muscles.
Biofeedback: This technique involves using monitoring devices to provide real-time feedback on muscle activity. By becoming aware of their jaw muscle tension, individuals can learn to control and reduce clenching behaviors.

It's crucial to consult with a dental professional to determine the most appropriate treatment plan based on individual needs and the severity of bruxism. Regular follow-ups ensure the effectiveness of the chosen interventions and allow for adjustments as necessary.

Preventive Measures for Bruxism

Preventing bruxism or minimizing its impact involves a combination of lifestyle modifications, stress management, and regular dental care.

Lifestyle Modifications

Limit Stimulant Intake: Reducing the consumption of caffeine and alcohol, especially in the evening, can decrease the likelihood of teeth grinding during sleep.
Avoid Chewing Non-Food Items: Habits like chewing on pens, pencils, or fingernails can exacerbate bruxism. Being mindful of these behaviors and replacing them with healthier alternatives can be beneficial.
Establish a Relaxing Bedtime Routine: Engaging in calming activities before bed, such as reading or taking a warm bath, can promote better sleep quality and reduce nighttime grinding.

Stress Management

Regular Exercise: Physical activity is a natural stress reliever. Incorporating regular exercise into one's routine can help in managing stress levels, thereby reducing bruxism episodes.
Mindfulness and Relaxation Techniques: Practices like meditation, deep breathing exercises, and progressive muscle relaxation can help in calming the mind and body, decreasing the likelihood of teeth grinding.

Regular Dental Check-Ups

Routine Examinations: Regular visits to the dentist allow for early detection of bruxism signs, such as tooth wear or jaw discomfort. Early intervention can prevent more severe complications.
Professional Guidance: Dentists can provide personalized advice on preventive measures, recommend protective devices like mouthguards, and monitor the effectiveness of implemented strategies.

By adopting these preventive measures, individuals can significantly reduce the risk of developing bruxism or mitigate its effects, leading to improved oral health and overall well-being.

Bruxism in Children

Bruxism, commonly known as teeth grinding or jaw clenching, is not exclusive to adults; it also affects children. Understanding its prevalence, causes, and management in younger individuals is essential for early intervention and prevention of potential complications.

Prevalence and Causes

Studies indicate that the prevalence of bruxism in children varies widely, ranging from 13% to 49% . Several factors contribute to bruxism in children, including:

Psychological Factors: Stress, anxiety, and hyperactivity can lead to teeth grinding in children.
Sleep Disorders: Conditions like sleep apnea or other sleep disturbances are associated with increased bruxism episodes.
Dental Issues: Misaligned teeth or an abnormal bite can cause discomfort, leading to grinding.
Medical Conditions: Certain neurological or developmental disorders have been linked to higher bruxism rates in children.

Symptoms to Watch For

Identifying bruxism in children can be challenging, as they may not be aware of the habit. Common signs include:
