What is the Difference Between Bruxism and Clenching

Bruxism and teeth clenching are common activities that can happen both during the day and at night. They are sometimes associated with periods of concentration, anger, or stress and often occur without a person being aware of it. Moreover, they can occur simultaneously as well.

The key difference between bruxism and clenching is their position. Bruxism involves moving the jaw with the teeth held together, while clenching involves holding the teeth together and tightening the jaw muscles.

What is Bruxism?

Bruxism is also known as teeth grinding. It is a condition in which people grind, gnash, or clench their teeth. There are two types of bruxism – one is where people may unconsciously clench their teeth when they are awake (aware bruxism) and the other one is where people may clench or grind their teeth during sleep (sleep bruxism).

Signs and symptoms of this condition include teeth grinding or clenching, teeth that are flattened, fractured, chipped or loose, worn tooth enamel, increased tooth pain, tired or tight jaw muscles or locked jaw, pain that feels like an earache, dull headache, damage from chewing on the inside of the cheek, and sleep disruption. Awake bruxism is caused by emotions such as anxiety, stress, anger, frustration, or tension or can be a coping strategy or a habit during deep concentration, whereas sleep bruxism is caused by sleep-related chewing activity associated with arousals during sleep.

Bruxism can be diagnosed through medical history, dental examination, and X-rays. Furthermore, bruxism can be treated through splints and mouth guards, dental correction, stress or anxiety management, behavior change, biofeedback, muscle relaxants, botox injections, and medication for anxiety or stress.

What is Clenching?

Clenching is a condition that involves holding the teeth together and tightening the jaw muscles. Clenching can be caused by different reasons, such as stress and anxiety, using caffeine before sleep, tobacco and alcohol use, dehydration, nutritional deficiencies like vitamin D and calcium, taking SSRI antidepressants, and sleep disorders. The symptoms of this condition may include jaw pain accompanied by a feeling of tightness, difficulty opening the mouth wide, tightness, and pain caused by excessive clenching, earaches, worn or loose teeth, or broken fillings.

Clenching can be diagnosed through medical history and dental examination. Furthermore, treatment options for clenching may include a relaxation therapist to teach people how to voluntarily relax their jaw muscles, as well as a sleep specialist to improve their sleep hygiene, lifestyle, and home remedies like drinking less caffeine during the day, getting more aerobic exercise during the day, getting between 30 to 60 minutes of direct sunlight each day in order to encourage a healthy circadian rhythm, avoiding screens like the phone and television two hours before going to bed and having a consistent sleep schedule, even on weekends.
