Strokes can result in which of the following oral problems?

• A. Oral sensory & motor deficits, poor tongue function & lip seal, dysphagia, reduced oral clearance of foods & increased food packing, increased caries & perio disease risk
• B. Reduced dexterity
• C. Osteonecrosis
• D. Stomatitis & mucositis

Answer: (A)

When a stroke affects the nerves and muscles that control the mouth and throat, you get a set of interconnected oral problems. Neuromuscular weakness and coordination issues in the tongue and lips lead to poor lip seal and limited tongue function, which in turn disrupts the oral phase of swallowing (dysphagia). If swallowing and oral clearance are reduced, food stays in the mouth longer and collects more easily, increasing food packing and the overall risk for dental caries and periodontal disease. Sensory changes can also alter how the mouth reacts to textures and stimulation, compounding these difficulties. This combination of sensory and motor oral deficits, dysphagia, and higher caries/periodontal risk most accurately reflects the oral problems seen after a stroke. Other options describe problems not typically caused by stroke, such as general dexterity issues, bone issues like osteonecrosis, or mucosal inflammation from treatments rather than stroke.
