What causes burning mouth syndrome?

Burning mouth syndrome can be primary or secondary. Some research suggests that primary burning mouth syndrome is caused by damage to the nerves that control pain and taste. Secondary burning mouth syndrome is usually caused by an underlying medical condition. Some of the problems that have been linked to secondary burning mouth syndrome include:[1][2] 
  • Dry mouth, which can be caused by various medications or underlying health problems
  • Other oral conditions, such as fungal infections, oral lichen planus, or geographic tongue
  • Nutritional deficiencies, such as lack of iron, zinc, folic acid, thiamin, riboflavin, pyridoxine, and cobalamin
  • Dentures, especially if they don't fit well and irritate the mouth
  • Allergies or reactions to foods, additives, dyes or dental work
  • Certain medications, in particular those for high blood pressure
  • Oral habits such as tooth grinding, tongue thrusting, or biting of the tongue 
  • Endocrine disorders, such as diabetes or hypothyroidism
  • Excessive mouth irritation which may result from over-brushing, use of abrasive toothpastes, over use of mouthwashes, or drinking too many acidic drinks
  • Psychological factors, such as anxiety, depression, or stress

For many people, the underlying cause of burning mouth syndrome can not be identified.[1][2]
