Teeth grinding, or bruxism, is a common condition that affects people of all ages, genders, and backgrounds. It can occur during the day or at night, but sleep bruxism is considered more harmful as individuals are unaware of the action and may clench their jaw more tightly, applying up to 250 pounds of force. Sleep bruxism is a sleep-related movement disorder that arises from the central nervous system and is linked to various risk factors, including stress, anxiety, lifestyle habits, and certain medications. The condition can lead to several symptoms, such as tooth erosion, headaches, jaw pain, and TMJ disorders, and may require treatment to manage its effects.

What You'll Learn

Sleep bruxism is a sleep-related movement disorder
Sleep bruxism, or teeth grinding during sleep, is a sleep-related movement disorder. It is characterised by the involuntary clenching, grinding, or gnashing of teeth while sleeping. Sleep bruxism is distinct from awake bruxism, and the former can cause more harm due to the lack of awareness during sleep.
Sleep bruxism is often challenging to diagnose as it occurs during sleep, and many people are unaware they are grinding their teeth. A sleeping person can exert up to 250 pounds of force while grinding their teeth, which can lead to tooth erosion, chipping, and other damage. It can also result in jaw pain, headaches, and temporomandibular joint (TMJ) disorders.
The exact cause of sleep bruxism is unknown, but it is believed to be associated with various risk factors. These factors include stress, anxiety, depression, and certain lifestyle habits such as smoking, alcohol consumption, and high caffeine intake. Sleep bruxism is also commonly observed in individuals with sleep disorders, such as sleep apnea, and other medical conditions like ADHD and epilepsy.
The condition is more prevalent in children, adolescents, and young adults, with estimates ranging from 6% to nearly 50% in this age group. However, it becomes less common with age, affecting around 8% of middle-aged adults and 3% of older adults.
Treatment options for sleep bruxism include custom mouth guards or night guards to protect the teeth from damage. Additionally, addressing the underlying causes, such as stress reduction and lifestyle modifications, can help manage the condition. In some cases, medication or muscle injections may be recommended to alleviate muscle soreness and headaches associated with bruxism.
Sleep bruxism can have serious consequences for oral health and overall well-being. It is important for individuals who suspect they may be grinding their teeth during sleep to consult a dentist or healthcare provider for proper diagnosis and treatment.

It can cause tooth erosion and damage
Bruxism, or teeth grinding, is a common condition that affects people of all ages, genders, and backgrounds. It can occur during the day or at night, but sleep bruxism is considered more harmful as individuals are unaware of the action and may clench their jaws more tightly, exerting up to 250 pounds of force.
Sleep bruxism can lead to tooth erosion and damage over time. Teeth can become flatter, shorter, or chipped due to chronic grinding. In severe cases, teeth may fracture, loosen, or even be lost, requiring extensive dental treatments such as bridges, crowns, root canals, implants, or dentures.
The condition is more prevalent in children, adolescents, and young adults, with an estimated 6% to 50% of children experiencing sleep bruxism. However, it often goes unnoticed as children's teeth and jaws change and grow rapidly, and most outgrow the habit without significant damage.
In adults, stress, anxiety, and certain lifestyle habits, such as smoking, alcohol consumption, and high caffeine intake, are common risk factors for bruxism. Managing these factors through stress reduction techniques and lifestyle modifications can help alleviate teeth grinding.
To protect teeth from further damage, dentists may recommend night guards or mouth guards, which cushion the teeth and prevent direct contact during grinding episodes. These guards are custom-made to fit an individual's teeth and can be an effective way to manage the condition and prevent tooth erosion.

Risk factors include stress, anxiety, and lifestyle habits
Teeth grinding, or bruxism, is a condition that can occur during sleep or while awake. Sleep bruxism is more common in children, adolescents, and young adults, and it can be challenging to diagnose since it happens during sleep, often going unnoticed.
Risk Factors
Stress and Anxiety
Stress and anxiety are significant risk factors for teeth grinding. People with depression or anxiety disorders such as major depressive disorder (MDD) or generalized anxiety disorder (GAD) are more prone to bruxism. Stress reduction techniques, such as meditation, exercise, and cognitive behavioral therapy, can help manage stress and reduce bruxism symptoms.
Lifestyle Habits
Certain lifestyle habits can also increase the risk of teeth grinding. These include:
- Smoking
- High alcohol consumption: Alcohol tends to intensify teeth grinding.
- High caffeine intake: Consuming more than six cups of coffee per day is associated with a higher risk of bruxism.
- Chewing on non-food items: Chewing on pencils, pens, or gum can contribute to teeth grinding.
Additionally, certain medical conditions and medications can also be risk factors for bruxism. These include sleep apnea, attention deficit hyperactivity disorder (ADHD), and certain antidepressants and antipsychotics.

Sleep bruxism is more common in children and young people
Bruxism, or teeth grinding, is a condition that can occur during the day or at night. Sleep bruxism is more common in children, adolescents, and young adults than in middle-aged and older adults. The prevalence of sleep bruxism in adolescents is estimated to be around 15%, while it occurs in around 8% of middle-aged adults and only 3% of older adults.
The exact prevalence of sleep bruxism in children is difficult to determine as it often goes unnoticed by parents and caregivers. Studies have found that anywhere from around 6% to up to nearly 50% of children may experience nighttime teeth grinding. Sleep bruxism can affect children as soon as their teeth come in, so even infants and toddlers may grind their teeth during sleep.
There are several risk factors associated with sleep bruxism in children and young people. One of the most significant risk factors is stress. Children with bruxism have been found to have a tendency towards anxiety and stress, and it is also strongly associated with Attention Deficit Hyperactivity Disorder (ADHD). Sleep bruxism has also been linked to sleep fragmentation and sleep-disordered breathing, such as upper airway obstruction caused by enlarged tonsils or adenoids.
The main symptom of sleep bruxism is the involuntary clenching and grinding of the teeth during sleep. People with sleep bruxism typically experience episodes of clenching and grinding that last up to one second, and these episodes tend to occur in clusters throughout the night. Sleep bruxism can lead to several negative consequences for oral health, including tooth wear, tooth damage, headaches, facial muscle pain, and discomfort during chewing.
Treatment options for sleep bruxism in children and young people may include physiotherapy and psychotherapy. Custom mouth guards or night guards can also help prevent dental issues and chronic pain associated with teeth grinding. Improving sleep hygiene has also been suggested as a helpful strategy in managing sleep bruxism.

Treatment options include custom mouth guards and stress reduction
Teeth grinding, or bruxism, can happen during the day or at night. It is difficult to know how many people grind their teeth because it often occurs during sleep. If left untreated, it can cause jaw pain, tooth erosion, TMJ disorders, and dental damage such as chipped teeth. It can also cause headaches, facial pain, tinnitus, and pain when eating or speaking.
The exact cause of teeth grinding is not fully understood, but it can be caused by a combination of factors. Common causes include stress, anxiety, sleep disorders, caffeine, alcohol, tobacco use, certain medications, and genetics.
Custom Mouth Guards
Custom mouth guards are the most common treatment for teeth grinding. They are typically made of acrylic or another hard material and are custom-fitted to the contours of your teeth. The process usually involves taking a mold of your teeth, either at a dentist's office or through an at-home kit, and then sending the impression to a lab to create a custom mouth guard. The mouth guard acts as a shock absorber, protecting your teeth from the effects of grinding.
Stress Reduction
Stress and anxiety are common causes of teeth grinding. Reducing stress through relaxation techniques and stress management can help ease the symptoms of bruxism. For example, finding ways to increase awareness of jaw clenching and grinding during the day can help reduce the habit.
