Grooved tongue is a common oral mucosal disease, its etiology is unknown and may be related to age, geography, systemic diseases, infections or genetic factors; the main symptom is that several deep grooves appear on the back of the tongue in the form of lobe or cerebral striations, grooved tongue is generally no obvious self-conscious symptoms, and occasional food irritation pain and other minor discomforts. 2. Generally there is no special treatment for furrowed tongue, local treatment is based on anti-inflammation and swelling, such as oral amoxicillin, etc. At the same time, systemic diseases must be controlled in order to prevent aggravation of symptoms; if the furrow is deeper and prone to recurring inflammation and infection due to food impaction or affecting the aesthetics, the furrow can be surgically excised and sewn to restore the tongue to its normal shape.
