The relationship of bruxism with temporomandibular joint dysfunction (TMD, or temporomandibular pain dysfunction syndrome) is debated. Many suggest that sleep bruxism can be a causative or contributory factor to pain symptoms in TMD. [3] [5] [9] [15] Indeed, the symptoms of TMD overlap with those of bruxism. [16] Others suggest that there is no strong association between TMD and bruxism. [4] A systematic review investigating the possible relationship concluded that when self-reported bruxism is used to diagnose bruxism, there is a positive association with TMD pain, and when stricter diagnostic criteria for bruxism are used, the association with TMD symptoms is much lower. [17] In severe, chronic cases, bruxism can lead to myofascial pain and arthritis of the temporomandibular joints. [ medical citation needed] Tooth wear [ edit ] Ohayon M.M., Li K.K., Guilleminault C.

Wearing a splint means that you will wear this down instead of your teeth which is a better option. Wearing a dental splint In adults, the causes of teeth grinding may reveal one or more of the following underlying medical conditions or prescription medication side effects: For many people, the presence of symptoms like tooth damage and jaw pain combined with reports of teeth grinding from a bed partner may be sufficient to determine that a person has sleep bruxism.

Gerstner, G. E. (2022, February 3). Sleep-related bruxism (tooth grinding). In A. F. Eichler (Ed.). UpToDate., Retrieved November 1, 2022, fromAccording to Darron Goralsky, principal physiotherapist and director of a Melbourne TMJ (temporomandibular joint — the jaw joint) and facial pain centre says that teeth grinding, or bruxism, "is a common condition that involves an individual involuntary grinding their teeth, generally while they are asleep". During sleep, people generally aren’t aware of their teeth grinding and can apply substantial pressure — up to 250 pounds of force

Historically, many believed that problems with the bite were the sole cause for bruxism. [10] [21] It was often claimed that a person would grind at the interfering area in a subconscious, instinctive attempt to wear this down and "self equiliberate" their occlusion. However, occlusal interferences are extremely common and usually do not cause any problems. It is unclear whether people with bruxism tend to notice problems with the bite because of their clenching and grinding habit, or whether these act as a causative factor in the development of the condition. In sleep bruxism especially, there is no evidence that removal of occlusal interferences has any impact on the condition. [7] People with no teeth at all who wear dentures can still have bruxism, [4] although dentures also often change the original bite. Most modern sources state that there is no relationship, or at most a minimal relationship, between bruxism and occlusal factors. [5] [25] [15] The findings of one study, which used self-reported tooth grinding rather than clinical examination to detect bruxism, suggested that there may be more of a relationship between occlusal factors and bruxism in children. [5] However, the role of occlusal factors in bruxism cannot be completely discounted due to insufficient evidence and problems with the design of studies. [5] A minority of researchers continue to claim that various adjustments to the mechanics of the bite are capable of curing bruxism (see Occlusal adjustment/reorganization). The ICSD-R states that 85–90% of the general population grind their teeth to a degree at some point during their life, although only 5% will develop a clinical condition. [7] Some studies have reported that awake bruxism affects females more commonly than males, [5] while in sleep bruxism, males and females are affected equally. [7] [8] In general, medications aren't very effective for treatment of bruxism, and more research is needed to determine their effectiveness. Examples of medications that may be used for bruxism include: Some amount of mouth movement is normal during sleep. Up to 60% of people make occasional chewing-like motions known as rhythmic masticatory muscle activities (RMMA), but in people with sleep bruxism, these occur with greater frequency and force. Medications help some people reduce sleep bruxism. Most of these drugs work by altering brain chemicals to reduce muscle activity involved in teeth grinding. Botox injections are another way of limiting muscle movement and have shown effectiveness in more severe cases of sleep bruxism.

Awake bruxism is thought to be usually semivoluntary, and often associated with stress caused by family responsibilities or work pressures. [5] Some suggest that in children, bruxism may occasionally represent a response to earache or teething. [22] Awake bruxism usually involves clenching [5] (sometimes the term "awake clenching" is used instead of awake bruxism), [23] but also possibly grinding, [4] and is often associated with other semivoluntary oral habits such as cheek biting, nail biting, chewing on a pen or pencil absent mindedly, or tongue thrusting (where the tongue is pushed against the front teeth forcefully). [4] Statistics about sleep bruxism in children are the hardest to pin down. Studies have found anywhere from around 6% to up to nearly 50% of children Bruxism is a repetitive jaw-muscle activity characterized by clenching or grinding of the teeth and/or by bracing or thrusting of the mandible. Bruxism has two distinct circadian manifestations: it can occur during sleep (indicated as sleep bruxism) or during wakefulness (indicated as awake bruxism)." [39] Tenderness, pain or fatigue of the muscles of mastication, [10] which may get worse during chewing or other jaw movement. [9] It started off as jaw soreness between 2012-2015 when I was studying because it was a stressful time. I was always clenching my jaw; it was my default."

The most common conventional treatment is a custom-made splint or mouth guard, specially designed to keep your teeth separated to prevent further damage due to the grinding or clenching. While some people find a mouth guard to be uncomfortable, it is one of the best ways to protect the health of your teeth. 2. Alignment Correction Lobbezoo F, Van Denderan RJ, et al.

Often when the cause is due to stress, depression or anxiety, doctors will prescribe muscle relaxants. While they may be effective, speak to your doctor about potential side effects as some commonly prescribed can adversely affect your liver or thyroid, while others may be habit-forming. 4.

In addition, home care tips can make it easier to cope with sleep bruxism.A dental splint looks very similar to a gumshield – as worn by sportspeople, and is worn over the upper or lower teeth to protect them. But it can also keep the airway open which enables the patient to breathe as normal and get a good night’s sleep. Another type of mouthpiece is a mandibular advancement device (MAD), which is best known for its use to reduce chronic snoring and mild obstructive sleep apnea. A MAD is held in place by the teeth and positions the lower jaw forward, helping to keep the airway open and in some cases limiting the extent of teeth grinding. This is typically used when bruxism is present with sleep apnea. Sleep bruxism is teeth grinding that happens during sleep, and is marked by movement of the masticatory muscles responsible for chewing.
