How is the crack in the corner of the mouth? The corners of the mouth are cracked, and the reasons need to be clarified. Usually, you can gradually recover by eliminating the cause, as shown below:

1, the bad habit of licking your lips: it is more common at ordinary times. If the corners of the mouth are cracked because of frequent licking, it is necessary to stop licking the corners of the mouth and correct bad habits. And you can apply chlortetracycline ointment or daily lip balm, and usually the squabble can gradually return to normal;

2. Fungal infection: mainly seen in special people, that is, patients with complete dentures. If secondary keratitis caused by fungal infection leads to corner cracking, it is mainly due to insufficient recovery of vertical distance of denture and candida infection on denture, which leads to keratitis and cracking. It is usually necessary to take targeted treatment, re-make dentures, restore vertical distance, and carry out antifungal treatment, which can usually improve quickly;

3. Malnutrition: it is rare at present, such as vitamin B2 deficiency or other vitamins deficiency, which leads to cracking of the corners of the mouth. Mainly due to long-term malnutrition of patients, some vitamins are taken too little, resulting in angular stomatitis, and corresponding vitamins need to be supplemented.
