This is an accident in the orbit of the maxilla and mandible of the oral cavity, which happens to everyone. Occasionally, because of loosening the oral muscles, I will bite several times repeatedly. Don't worry, you can only be more careful in the future. You can take two tablets of vitamin B2 to prevent local mucosal ulcers from being bitten. Eating a little Banlangen tablets or Compound Chuanxinlian tablets can clear away heat and detoxify. If you are young, you can eat nothing, just drink more water.
