What Causes Bruxism in Adults?
Many people believe that teeth grinding (bruxism) is a phenomenon that occurs only in children. However, in recent years, some adults have noticed that they frequently grind their teeth during sleep. In fact, there are numerous underlying causes for this condition, which warrant careful evaluation. So, what causes bruxism in adults?
What Causes Bruxism in Adults?
Most cases of adult bruxism stem from excessive stress, a fast-paced lifestyle, and psychological tension. Additionally, some adults develop bruxism due to malocclusion—abnormal alignment or contact between upper and lower teeth during chewing. If bruxism symptoms occur, a custom-fitted occlusal guard (night guard) may be used to protect the teeth from damage. Such guards can be fabricated and fitted by dental prosthodontists at reputable hospitals. Note, however, that these devices are highly individualized; some adults experience discomfort or disrupted sleep after wearing them, in which case occlusal guards are not recommended.
Common causes of bruxism in adults include calcium deficiency, neurasthenia (a functional disorder characterized by fatigue, anxiety, headache, and irritability), and ascariasis (roundworm infection). Calcium deficiency increases neuronal excitability, thereby impairing sleep quality and triggering bruxism. Neurasthenia directly disrupts normal sleep patterns, with symptoms including vivid dreams, bruxism, and insomnia. Under medical supervision, patients may try calcium carbonate chewable tablets to correct calcium deficiency and vitamin B1 (thiamine) or gamma-oryzanol to help regulate nervous system function. Although the precise mechanism linking ascariasis to bruxism remains unclear, diagnosis can be confirmed via clinical examination; treatment typically involves levamisole.
Patients are advised to maintain good general and oral hygiene. In addition, an occlusal guard may be considered to prevent tooth wear; such devices are available through the Department of Prosthodontics at accredited hospitals. We hope this information is helpful to you.
