”Burning mouth syndrome” is a group of symptoms that occur in the oral mucosa, mainly manifested by burning-like pain. Accompanying symptoms include dry mouth, change in taste, headache, and mood changes (depression, anxiety, irritability). The oral examination is usually not characterized by obvious clinical damage, and the tongue mucosa is normal or has only mild lingual papillitis. The disease has a high incidence in menopausal or menopausal women. The etiology may include local adverse stimuli (such as tartar, bad restorations, residual crowns, etc.), endocrine changes, oral flora dysbiosis, vitamin or trace element deficiency, some systemic diseases such as diabetes, anemia, rheumatoid, gastrointestinal disorders, and hypnotic and hypotensive drugs often taken by the elderly may also cause dry mouth and burning pain in the tongue. Treatment includes removal of suspected triggers, treatment of related systemic diseases, psychotherapy and local symptomatic treatment. In addition, it is also helpful for patients to participate in some relaxing activities and maintain a happy mood to relieve pain symptoms.
