Teeth clenching and grinding, known as bruxism, is a common condition that often occurs during sleep. Sleep bruxism is considered a sleep-related movement disorder that arises from the central nervous system. It can cause various symptoms, including headaches, jaw pain, tooth erosion, and TMJ disorders. While the exact causes of bruxism are not fully understood, it is associated with stress, anxiety, certain medications, and lifestyle factors such as caffeine consumption, alcohol intake, and smoking. Treatment options include mouth guards, behaviour changes, and addressing any underlying sleep disorders or medical conditions.

Bruxism: The medical term for clenching and grinding teeth
Bruxism is the medical term for clenching and grinding teeth. It usually occurs subconsciously, during sleep or when awake. It can cause severe dental damage and jaw pain if left untreated. Bruxism is more common during sleep, and it can be difficult to detect as it often goes unnoticed by the person affected. However, a sleep partner might hear the grinding at night.
Sleep bruxism, or nocturnal bruxism, can cause more harm than daytime bruxism because those affected are unaware of their actions. People with sleep bruxism often require treatment to manage the effects, such as mouth guards to protect their teeth from damage.
The exact causes of bruxism are not fully understood, but several factors can contribute to the condition. These include stress, anxiety, certain medications, and lifestyle habits such as smoking, alcohol consumption, and high caffeine intake. Bruxism is also associated with various medical conditions, including sleep disorders like sleep apnea, neurological disorders, and gastroesophageal reflux disease (GERD).
While the condition can occur at any age, it is most prevalent during childhood, adolescence, and young adulthood. Symptoms of bruxism may include tooth erosion, jaw pain, headaches, and TMJ disorders. In severe cases, bruxism can lead to tooth flattening and other health complications.
Treatment options for bruxism include custom mouth guards, biofeedback therapy, medication, and botulinum toxin injections for severe cases that do not respond to other treatments. Lifestyle changes, such as reducing caffeine and alcohol intake, can also help manage bruxism.

Sleep-related bruxism: More common than daytime bruxism
Bruxism involves the clenching, grinding, or gnashing of teeth and can occur during sleep or while awake. Sleep bruxism, or teeth grinding during sleep, is more common than daytime bruxism. This condition is characterised by the activation of masticatory muscles responsible for chewing. Sleep bruxism is more prevalent in children, adolescents, and young adults, with estimates ranging from 6% to nearly 50% in children and around 15% in adolescents. The condition becomes less common with age, affecting about 8% of middle-aged adults and 3% of older adults.
Sleep bruxism can cause more harm than daytime bruxism because individuals are often unaware of their nocturnal teeth grinding. The lack of awareness during sleep can lead to tighter clenching and the application of up to 250 pounds of force. This can result in dental issues such as tooth erosion, jaw pain, TMJ disorders, and tooth fractures. Additionally, bruxism can lead to tooth sensitivity due to the exposure of the underlying dentin layer.
The exact causes of sleep bruxism are not fully understood, but it is often associated with stress, anxiety, and certain personality traits. Individuals with nervous tension, anger, pain, frustration, aggression, or a competitive nature may be more prone to sleep bruxism. Sleep disorders such as obstructive sleep apnea, sleep talking, and sleepwalking are also risk factors. Additionally, there may be a link between bruxism and certain neurological disorders, such as Rett syndrome, GERD (gastroesophageal reflux disease), and TMD (temporomandibular dysfunction).
Lifestyle habits can also contribute to sleep bruxism. For example, individuals who smoke, consume excessive alcohol, or drink large amounts of caffeine are at a higher risk. Certain medications, such as antidepressants, have also been implicated as potential risk factors.
Managing sleep bruxism involves improving sleep hygiene, addressing stress, and seeking dental interventions. Maintaining consistent sleep and wake times, avoiding naps, regular exercise, and reducing caffeine, alcohol, and tobacco intake are recommended. Biofeedback tools can help monitor muscle activity in the mouth and jaw, aiding in behaviour modification. Dental interventions, such as custom mouth guards, can prevent dental issues and chronic pain.
In summary, sleep-related bruxism is more common than daytime bruxism and can have more severe consequences due to the lack of awareness during sleep. The condition is associated with various risk factors, including stress, anxiety, personality traits, sleep disorders, and lifestyle habits. Effective management involves a combination of improved sleep hygiene, stress reduction, and dental interventions to minimise the harmful effects of teeth grinding.

Risk factors: Stress, anxiety, and lifestyle habits
Clenching or grinding your teeth during sleep, known as sleep bruxism, can cause more harm than doing so while awake because it often goes unnoticed and untreated. Sleep bruxism is often a result of stress, anxiety, and certain lifestyle habits.
Stress and anxiety are significant risk factors for teeth clenching. Individuals with depression or anxiety disorders such as major depressive disorder (MDD) or generalized anxiety disorder (GAD) are more susceptible to bruxism. Feeling overwhelmed and stressed can lead to teeth clenching, which may be a coping mechanism or a result of increased muscle tension in the jaw. Practicing mindfulness and stress management techniques can help reduce the risk of bruxism associated with stress and anxiety.
Lifestyle habits also play a crucial role in teeth clenching while sleeping. Certain habits, such as smoking, alcohol consumption, and high caffeine intake (more than six cups of coffee per day), have been linked to an increased risk of bruxism. The impact of these habits may be due to the stimulating effects of nicotine, alcohol, and caffeine, which can heighten muscle tension and affect sleep quality. Additionally, recreational drug use can also contribute to teeth clenching. Making positive lifestyle changes, such as reducing or avoiding these substances, can lower the chances of developing bruxism and improve overall health.
While the exact cause of teeth clenching during sleep may vary among individuals, addressing stress and anxiety through relaxation techniques and seeking professional help for managing mental health disorders can be beneficial. Additionally, improving lifestyle habits by reducing substance use and limiting caffeine intake can also lower the risk of sleep bruxism. It is important to note that untreated bruxism can lead to jaw pain and dental damage, so regular dental check-ups are essential for monitoring and treating any potential issues.

Diagnosis: A dentist may diagnose bruxism, but a sleep study may be needed
Clenching one's teeth while sleeping is known as sleep bruxism, a type of bruxism, which involves teeth grinding and jaw clenching during sleep. It is difficult for people to be aware that they are grinding their teeth while sleeping, which makes diagnosis challenging. Sleep bruxism is more common in children, adolescents, and young adults.
Diagnosis of sleep bruxism is usually straightforward and can be done by a dentist or a doctor. It involves the exclusion of dental diseases, temporomandibular disorders, and the rhythmic jaw movements associated with seizure disorders. The diagnostic process can vary depending on the type of health professional providing care. For those living with others, a diagnosis of grinding is relatively simple, as housemates or family members can inform the patient of recurrent grinding. Those living alone can use a sound-activated tape recorder or devices like Bruxchecker, Bruxcore, or a beeswax-bearing biteplate to confirm the condition.
An overnight study in a sleep clinic, known as polysomnography, is the most conclusive way to diagnose sleep bruxism. However, polysomnography can be expensive and time-consuming and may not be necessary in all cases. Questionnaires can also be used to screen for bruxism in clinical and research settings.
Occlusal splints, or custom mouth guards, are usually employed as a treatment for bruxism, but they can also be used diagnostically to observe the presence or absence of wear on the splint after a period of nighttime use. The Individual (personal) Tooth-Wear Index was developed to objectively quantify the degree of tooth wear in an individual, without being affected by the number of missing teeth.

Treatment: Mouth guards, medication, and lifestyle changes can help
Clenching or grinding your teeth while sleeping is known as bruxism. It can cause various issues, including headaches, tooth or jaw pain, and damaged teeth. Treatment options include mouth guards, medication, and lifestyle changes.
Mouth Guards
Mouth guards, also known as night guards, are a common treatment for bruxism. They are retainer-like soft or hard plastic pieces that cover either the top or bottom set of teeth. Mouth guards cushion the teeth from the force of clenching and prevent teeth grinding, thereby preventing potential dental issues such as inflamed gums, cracked teeth, and jaw joint disorders. Custom-made mouth guards are typically more comfortable and effective than store-bought ones, as they are designed to fit the patient's teeth precisely. However, store-bought options, such as boil-and-bite guards, are also available and can provide a more customized fit than standard stock guards.
Medication
In severe cases of bruxism, healthcare providers may recommend botulinum toxin injections (Botox) to relax the jaw muscles and reduce pain. This treatment typically needs to be repeated every three to four months.
Lifestyle Changes
Bruxism is often caused by stress and anxiety. Therefore, stress-relieving exercises and activities, such as regular exercise, can help reduce teeth clenching and grinding. Tongue and jaw muscle exercises are also recommended to alleviate teeth soreness. Additionally, a warm bath before bed or applying a heating pad to the jaw can relax the jaw muscles and reduce teeth grinding.
