Trauma: If the lip is broken due to trauma, the slightly damaged person only needs to clean the wound with normal saline or hydrogen peroxide, and then apply erythromycin ointment after disinfection with iodophor, so as to achieve the purpose of detumescence, anti-inflammation and pain relief. If the wound is deep and long, it should be carefully cleaned before suture, and the patient needs to change the dressing on time, which generally recovers quickly;
2, oral ulcer: if there is an oral ulcer, it may also lead to lip rupture, which may be caused by lack of vitamins. If you want to recover quickly, you need to actively treat the cause at this time, such as taking oral vitamins, such as vitamin B, and adjusting the dose according to the doctor's advice. You can also rinse your mouth with chlorhexidine. Such people should usually eat more fresh fruits and vegetables to supplement vitamins, folic acid and other nutrients needed by the human body to relieve oral ulcers;
3. Other reasons: If the lips are broken due to dry weather and low drinking water, you can moisten your lips by properly adjusting indoor humidity, drinking plenty of water and applying sesame oil to the affected area to promote the rapid healing of the wound. If the lip rupture is caused by eating too much spicy and irritating hot food recently, such people can take Niuhuang Jiedu pills and other heat-clearing and detoxicating drugs according to the doctor's advice, drink Lycium barbarum chrysanthemum tea and honeysuckle tea appropriately, and pay attention to keeping a light diet, which can also promote the rapid recovery of the wound.
