As per a study carried out by the Department of Dermatology, Mayo Clinic, Rochester (USA) in 2017, people who have the symptoms of burning mouth syndrome (BMS) should get screened for fasting blood glucose, vitamin D (D2 and D3), vitamin B6, zinc, vitamin B1, and TSH.

This burning pain or hot sensation is typically felt on the lips or tongue, or more widespread in the mouth. Along with that, a person may experience numbness, dryness and unpleasant taste in the mouth. The pain could get worse when eating something. The researcher suggests that the condition pertain if the root cause of the problem is not tackled efficiently. The severity of the condition may vary from person to person.
