Is every case of a burning tongue the same condition?

No. We first look for causes that can be seen or confirmed through tests, such as stomatitis, infections, irritation from dental materials, dry mouth, or nutritional deficiencies.

What information should I record?

Please note the time of day when symptoms worsen, the relationship with food, dry mouth and changes in taste, medications you are taking, and the timing of any dental treatments.

How is the diagnosis made?

Burning Mouth Syndrome is diagnosed after identifying causes that create similar symptoms, such as oral infections, wounds, dry mouth, nutritional deficiencies, diabetes, or the effects of medication. Even if there are few visible changes, the pain and burning sensation felt by the patient are symptoms that must be addressed during medical evaluation.

What additional factors are considered in heat-cold (Han-yeol) medical evaluation?

Based on the results of necessary dental and medical evaluations, we also examine dry mouth, thirst, sleep, nighttime heat sensations, digestion, and tension responses. While continuing current treatments and medications, Korean medicine treatment determines the primary goal among oral heat, dryness, and sleep, and sets the direction for the herbal medicine prescription.

There may be no visible wounds even if the inside of your mouth feels burning.

Burning Mouth Syndrome is a painful condition characterized by prolonged burning, stinging, or tingling sensations in the tongue, lips, palate, or various parts of the mouth. There may be no clear abnormalities when looking inside the mouth, and it may be accompanied by dry mouth or taste changes, such as a bitter or metallic taste.

Commonly confused terms and their differences: Temporary irritation after spicy or hot foods, stomatitis, Candida infections, and dental problems are not the same as Burning Mouth Syndrome. First, causes such as oral diseases, medications, nutritional deficiencies, diabetes, thyroid issues, and dry mouth are excluded through examination and necessary tests to distinguish whether the condition is primary or secondary.
Information to record before your visit: Record the exact area that burns, the time it started, whether it is present from the morning or worsens in the afternoon, and changes after eating, drinking water, or brushing teeth. You should also inform your dentist or medical provider about photos of the inside of your mouth, taste changes, dentures, dental treatments, new medications and health supplements, dry mouth, reflux, or teeth-clenching habits.
Scope of this material: NIDCR data was used to explain the symptoms of Burning Mouth Syndrome and the diagnostic process of excluding other causes. Do not determine a condition of deficiency or heat, or apply irritating folk remedies, based solely on the feeling of a burning tongue. If you experience new ulcers, bleeding, swelling, difficulty swallowing, or weight loss, you must not delay an oral examination.

Heat and Cold ColumnI feel a burning sensation in my mouth, but my test results are normal. Why is this happening?

We provide information on why burning mouth syndrome may not appear in tests, the causes viewed from the perspective of the body's heat, and criteria for self-assessment.

Heat and Cold ColumnBurning Mouth Syndrome: Can the inside of my mouth feel burning even if tests are normal?

When the tongue and mouth feel as if they are burning but look normal on the outside, we explain how to distinguish Burning Mouth Syndrome from other causes and what is evaluated in Korean medicine treatment.

Medical GuideWhat should I check if tests are normal but sensations of heat and cold persist?

Just because a cause was not found in a test does not mean the symptoms the patient feels do not exist. The Baekrokdam Heat-Cold Clinic respects existing results while examining details not captured in test reports, such as location, timing, sleep, sweat, and digestion, categorizing them by heat-cold patterns to find points where Korean medicine treatment can help.

Medical TerminologyDifferential Diagnosis

Differential diagnosis is the process of distinguishing possible causes one by one through examination, testing, and monitoring progress, rather than determining a disease name based on a single symptom. This is the first and most necessary step for both sensations of heat and cold.

Korean Medicine ConceptHeat syndrome

Heat syndrome refers to a tendency where various body signals converge toward a 'hot' direction. It is not a disease name referring to fever caused by infection or thyroid disease, so necessary differential diagnosis is required first.
