Mouth is dry and burning

A dry, burning mouth can come from reduced saliva, irritation, medicines, or oral disease and should be assessed if it persists.

Dry mouth means the mouth feels dry or produces too little saliva, while burning describes heat, stinging, or tenderness of the tongue, lips, or lining. Dehydration, mouth breathing, tobacco, alcohol, spicy products, yeast overgrowth, reflux, nerve changes, and many medicines can be involved.

Sip water regularly, use sugar-free gum or lozenges to stimulate saliva, and avoid tobacco, alcohol-containing rinses, and foods that clearly sting. Brush with fluoride toothpaste and arrange a medication review with the prescribing clinician rather than stopping a medicine yourself.

Arrange dental care if dryness or burning lasts, causes sores, changes taste, makes swallowing difficult, or leads to repeated decay. Seek prompt medical or dental assessment for facial swelling, fever, extensive sores, or inability to drink.

Ask whether the tissues show irritation, decay, fungal changes, reflux-related injury, or another oral condition. Ask how saliva flow, medicines, nutrition, and whole-body symptoms should be evaluated together.
