Stroke / TIA (cerebrovascular disease)
Cardiovascular
How likely this condition is to affect the mouth.
Strength of the peer-reviewed evidence.
Oral health effects
Impaired oral hygiene from hemiparesis/facial weakness
Reduced manual dexterity and lip seal from hemiplegia or facial weakness raise plaque accumulation, caries, and periodontal risk; drooling can also occur.
Clinical management: Recommend modified or electric toothbrushes, caregiver-assisted hygiene, and shorter, more frequent recall.
Dysphagia and aspiration risk
Swallowing difficulty is common after stroke and raises the risk of aspirating oral secretions or debris during treatment.
Clinical management: Treat in a semi-upright position, use high-volume suction, and use a rubber dam where feasible.
Aphasia affecting consent and instructions
Receptive or expressive aphasia can complicate informed consent and following home-care instructions.
Clinical management: Involve a caregiver or healthcare proxy; use simplified, written, or visual instructions.
Bleeding risk from secondary-prevention medications
Most stroke survivors are maintained on long-term antiplatelet or anticoagulant therapy to prevent recurrence, raising bleeding risk with invasive procedures.
Clinical management: Confirm the current antithrombotic regimen and coordinate with the prescriber before invasive care; see the specific medication for detailed guidance.
Gum disease as a stroke risk factor (periodontitis association)
Periodontitis is associated with roughly double the risk of stroke, especially ischemic stroke, so periodontal control matters for secondary prevention.
Clinical management: Assess and treat periodontitis; set short maintenance intervals; recommend adaptive aids (powered/modified-handle brushes) and caregiver-assisted care when hemiparesis limits hygiene.
