Which are the symptoms of Burning Mouth Syndrome?

Burning Mouth Syndrome is a chronic condition characterized by a persistent, burning sensation in the mouth, most commonly affecting the tongue, without any clinically apparent lesion or medical cause. Symptoms typically manifest as a daily, moderate-to-severe pain that can fluctuate in intensity throughout the day or remain constant for months or even years.

What are the primary symptoms of Burning Mouth Syndrome?

Patients with Burning Mouth Syndrome frequently describe the sensation as if the mouth has been scalded by hot liquid or coffee. While the oral mucosa usually appears healthy upon clinical examination, the subjective pain is profound. Common symptoms include:

• A persistent burning or stinging sensation, most often on the tip or sides of the tongue, the roof of the mouth (hard palate), or the lips.


• Xerostomia, or a subjective feeling of dry mouth, even when saliva production is normal.


• Dysgeusia, defined as a persistent metallic, bitter, or altered taste in the mouth.


• Increased sensitivity to certain foods, particularly spicy, acidic, or carbonated items.


• Numbness or tingling sensations, often described as paresthesia.

How does Burning Mouth Syndrome impact daily life?

The impact of Burning Mouth Syndrome on quality of life is significant. Because the pain often interferes with eating and drinking, many patients experience unintended weight loss or nutritional deficiencies. Furthermore, the constant nature of Burning Mouth Syndrome pain often leads to secondary issues, including sleep disturbances, chronic anxiety, and social withdrawal. For the 21 members of our DiseaseMaps community living with this condition, these symptoms represent a daily challenge that requires a multidisciplinary approach to manage.

When should I seek medical attention?

While Burning Mouth Syndrome itself is not life-threatening, you should consult a healthcare professional if you notice visible mouth sores, persistent white patches, bleeding, or difficulty swallowing, as these may indicate secondary causes rather than primary Burning Mouth Syndrome. Immediate evaluation is also warranted if the pain interferes significantly with your ability to maintain hydration or nutrition.

Next steps

• Consult an oral medicine specialist or an otolaryngologist (ENT) to rule out secondary conditions like anemia, diabetes, or thyroid dysfunction.


• Maintain a "pain diary" to track food triggers and stress levels, which can exacerbate Burning Mouth Syndrome.
