Abstract
Oral health and sleep health are rarely discussed in the same clinical conversation, yet the biological evidence linking them is both substantial and growing. Chronic sleep deprivation triggers a cascade of systemic disruptions, including immune dysregulation, hormonal imbalance, and oxidative stress, which leave unmistakable marks on the oral cavity. Despite this, sleep analysis remains largely absent from routine dental assessment, and its role as an independent driver of oral disease has yet to receive the clinical attention it deserves. This article provides a comprehensive narrative review of the mechanisms through which sleep deprivation compromises oral health, organized around five interconnected domains: the immunological consequences of sleep loss, including its role in periodontal destruction and impaired mucosal healing; disruptions to the salivary environment and their downstream effects on caries, xerostomia, and halitosis; behavioral and lifestyle mediators such as glycemic dysregulation, tobacco use, and caffeine consumption; neuromuscular and structural consequences encompassing bruxism, temporomandibular dysfunction, traumatic dental injuries, and dysphagia; and obstructive sleep apnea as a major oral health comorbidity that both reflects and reinforces sleep deficiency. The article further addresses the practical implications of these findings for clinical dental practice, outlining how dentists can incorporate sleep-related screening into routine assessments through validated questionnaires, anatomical risk evaluation, and recognition of characteristic oral markers, and when referral to a sleep medicine specialist is warranted. The evidence reviewed here positions sleep deprivation as a significant, independent risk factor for a broad range of oral conditions and supports the integration of sleep health into a more comprehensive, patient-centered model of dental care.
