Burning mouth syndrome is the medical term for ongoing (chronic) or recurrent burning in the mouth without an obvious cause. This discomfort may affect the tongue, gums, lips, inside of your cheeks, roof of your mouth or widespread areas of your whole mouth. The burning sensation can be severe, as if you scalded your mouth.
Burning mouth syndrome can appear suddenly or develop gradually over time. Unfortunately, the cause often can't be determined. Although that makes treatment more challenging, you can often get burning mouth syndrome under better control by working closely with your health care team.
