If the tongue is bitten by teeth, if it is cracked, it needs to be sutured. If it is not cracked, but only the surface mucosa is damaged, some mouthwash and anti-inflammatory medicine can be applied for symptomatic treatment, and the surface anti-inflammation can promote rapid healing. For damage to the surface of the tongue, antibiotics and mouthwash can be applied on the basis of suturing to promote the healing of the mucosa and to prevent the persistence of inflammation. Once the tongue is split, it must be treated in a timely manner according to the principles of tongue suturing to avoid the risk of abnormal tongue movement and tongue shortening after the injury, which may cause some voice articulation disorders, and timely examination is needed to prevent the persistent occurrence and existence of internal infection causing erosion, pain and swelling.
