Burning teeth and gums
Burning teeth and gums can reflect sensitivity, inflamed gingiva, chemical irritation, decay, or another condition requiring an oral examination.
The short answer
Burning in teeth and gums is a symptom rather than a diagnosis and can arise from exposed dentine, gingival inflammation, chemical irritation, decay, or nerve-related pain.
How can burning differ from sensitivity or gum inflammation?
Dentine sensitivity usually causes a brief response to cold, touch, or sweet foods, while inflamed gums may bleed, swell, or feel tender. Spontaneous or lingering tooth pain raises concern for pulpal inflammation rather than simple surface sensitivity.
What can you do while the cause of burning is unclear?
Use a soft brush, clean gently along the gumline, and avoid products that sting or contain strong flavouring until the cause is clear. Do not place aspirin or concentrated peroxide directly on the gums, and note which foods or temperatures trigger symptoms.
When does burning in teeth or gums need checking?
Arrange an examination for persistent burning, bleeding, swelling, bad taste, a loose tooth, or pain that interrupts sleep. Facial swelling, fever, or difficulty swallowing or breathing needs urgent assessment.
What should you ask about burning teeth and gums?
Ask the dentist to test the tooth nerve, inspect the gums and exposed roots, and check for decay, cracks, erosion, or an irritating product. Ask whether you need a desensitizing treatment, periodontal care, a restoration, or endodontic treatment.
Frequently asked questions
Can gum inflammation make teeth feel hot or burning?
Yes. Inflamed gingiva can make the gumline tender, and exposed root surfaces can add temperature sensitivity, but a painful tooth still needs testing.
Can mouthwash cause burning?
Some ingredients can irritate sensitive oral mucosa; stop the suspected product and seek advice if symptoms persist.
