Bruxism is a common problem affecting a large part of the population and yet surprisingly little attention is paid to it. It is true that in most cases it does not require more treatment than the use of a discharge splint at night, but more rarely it can be related to other more serious underlying disorders.
It must be said that the causes of bruxism are not fully known, but it is known that in most cases of daytime bruxism it is related to psychological factors such as anxiety, stress or tension ; In contrast, during sleep it is considered a parasomnia that occurs in stages 2 and 3 of non-REM sleep.
However, it has been observed that it appears more frequently in people with certain pathologies or risk factors , so it could point to the presence of another disease.
Specifically, it is especially prevalent in patients with Parkinson’s disease, dementia, gastroesophageal reflux disorder, epilepsy, night terrors, other sleep disorders and in people with attention deficit hyperactivity disorder (ADHD).
Likewise, there are substances such as certain antidepressant drugs, amphetamine drugs, tobacco, alcohol, caffeine and illegal substances such as mdma, cocaine or methamphetamine that increase their prevalence, even causing severe episodes during their effect.
Bruxism, normally, does not cause serious complications in itself (although in severe cases it can cause significant damage to the teeth, tension headaches, facial or neck pain and disorders in the jaw joints), but it is important that it is subject to medical control so that measures can be taken to minimize your risks and to identify the possible underlying cause, even if this is a sleep disorder or a high level of stress.
