Oral Health Management in Stroke Rehabilitation

Stroke survivors often face impairments in motor control, cognition and swallowing that compromise routine oral hygiene, elevating the risk of dental decay, periodontal disease and respiratory complications. Dysphagia promotes residue retention and aspiration, while reduced manual dexterity and cognitive deficits further limit self-care. Neglected oral health in this population is strongly linked to stroke-associated pneumonia, poorer nutritional intake and diminished quality of life. Effective management requires a multidisciplinary approach integrating dental professionals, nurses, speech and language therapists, dietitians and carers. Core elements include individualised assessment, standardised oral care protocols, mechanical plaque removal, chemical adjuncts and patient or caregiver education. Emerging evidence also highlights the diagnostic and prognostic value of the oral microbiome in predicting infectious complications. Integrating oral health into rehabilitation pathways not only reduces morbidity but also supports functional recovery, enhances comfort and underpins holistic stroke care on a global scale.

Research from Nature Portfolio

An interventional study evaluated advanced versus conventional oral hygiene regimes during outpatient stroke rehabilitation. Participants receiving a powered toothbrush combined with antiseptic mouthrinse and tailored instruction demonstrated significantly greater improvements in both oral health-related quality of life and general health scores over a six-month period compared with those using manual brushing alone. These findings underscore the importance of augmenting mechanical cleaning with chemical agents and structured education to achieve sustained benefits within stroke services.

The graph below shows the total number of articles in oral health management in stroke rehabilitation across all publications each year (not limited to Nature Index journals).

Technical terms

Dysphagia: Impairment in the ability to swallow safely and effectively, common after stroke.

Oral microbiome: The complex community of microorganisms inhabiting the oral cavity, which can influence systemic health and infection risk.

Stroke-associated pneumonia: Lower respiratory tract infection occurring after stroke, often linked to aspiration of oral or pharyngeal contents.

Oral health-related quality of life (OHRQoL): A patient-centred measure reflecting the impact of oral conditions on daily activities, comfort and social interaction.

Chlorhexidine: A broad-spectrum antiseptic agent used as a mouthrinse to reduce oral pathogens and plaque formation.
