What is Bruxism?

Bruxism is a medical condition in which a person grinds their teeth or clenches their jaws. It is a parafunctional activity that can occur during sleep or while awake. Bruxism involves involuntary or conscious teeth grinding which puts excessive force on the teeth and jaws.

Causes of Bruxism

There are several potential causes for bruxism:

– Stress or anxiety – Stress is one of the major triggers for bruxism as teeth grinding can help release tension in the body. High levels of stress hormones like cortisol may induce bruxism .

– Sleep disorders – Conditions like sleep apnea where breathing is interrupted during sleep have been linked to nocturnal bruxism. Irregular breathing can disturb sleep patterns causing teeth grinding.

– Genetics – Some studies have found that Bruxism Treatment runs in families, indicating a possible genetic predisposition.

– Medication side effects – Certain medications like antidepressants, decongestants, and stimulants are known to sometimes induce bruxism as a side effect by altering brain activity.

– Gastroesophageal reflux disease (GERD) – Chronic acid reflux involving the swallowing of stomach acid has been associated with awake bruxism. Stomach acid reaching the throat may trigger teeth grinding.

– Diet – Consumption of certain foods and beverages containing caffeine, alcohol, or nicotine before bedtime can trigger sleep bruxism in susceptible individuals.

Diagnosis of Bruxism

A dentist can usually diagnose bruxism based on physical exam findings and patient history. Some signs that indicate bruxism include:

– Tooth wear – Excessive grinding over years leads to flattened, rough, or ridged tooth surfaces with abnormal tooth shape.

– Jaw pain – Pain in the jaw muscles, temples or face is commonly reported especially upon waking up.

– Grinding sounds – A bed partner may notice audible grinding noises coming from the individual during sleep.

– Indentations on tongue – Teeth marks or indentations may be visible on the tongue and inner cheeks from pressing during a bruxism episode.

– Morning headaches – Grinding at night can cause muscle fatigue leading to headaches upon waking up.

If needed, the dentist may ask the patient to wear a special appliance called a bruxism night guard or mouthguard to monitor grinding overnight in the dental office. Audio or video recording may also help confirm the diagnosis.

Bruxism Treatment Options

Treatment depends on the severity of bruxism but focuses on protecting teeth from damage and reducing muscle tension:

Night guards or mouthguards: Custom-made mouthguards are the standard first-line treatment recommended by dentists. Worn only at night, they shield the teeth from grinding pressures. Over-the-counter guards are less effective.

Biofeedback/electromyography (EMG): This involves attaching sensors to jaw muscles to monitor teeth clenching activity. The feedback helps train patients to become aware and relax their jaw muscles.

Stress management: Cognitive behavior therapy, meditation, deep breathing exercises, and yoga can help address underlying stress or anxiety contributing to awake bruxism.

Botox injections: Botox temporarily weakens jaw muscles to prevent teeth clenching. It may provide 6-9 months of relief but side effects are possible with long-term use.

Night splint: Worn like a night guard, soft splints keep the lower jaw in a forward position to prevent teeth grinding. They also relax clenching muscles.

Prescription medications: In select cases, muscle relaxants or anti-anxiety medications may be tried short-term under medical guidance to stop teeth grinding episodes.

Lifestyle changes: Avoiding alcohol, caffeine, and quitting smoking helps reduce triggers. Maintaining good posture during daytime and using a supportive pillow at night can ease jaw muscle strain.

Managing Underlying Conditions: Effective treatment of medical issues linked to bruxism like sleep apnea with CPAP therapy or GERD with antacids reduces grinding incidents.

Follow-up and prevention: Regular dental exams and replacing guards as needed allows catching early signs of tooth damage for timely intervention. Targeting risk factors helps prevent bruxism relapse over the long-term.

Long-term Outlook of Bruxism Treatment

While bruxism itself may not cause permanent damage, failure to adopt protective measures and lack of treatment increases the risk of detrimental oral health consequences over decades. With proper diagnosis and a multidisciplinary treatment approach tailored to the individual, bruxism can be managed successfully in many cases. Focusing on identifying triggers, relieving jaw muscle tension, and educating patients about prevention measures results in a favorable long-term prognosis in most instances where bruxism is addressed promptly. Combined therapies work best but simply wearing a night guard at night as directed offers good protection against tooth wear from grinding. Periodic follow-ups aid monitoring symptoms and tooth condition to modify treatment as needed.
