Food debris in the wisdom tooth cavity can be removed by rinsing with a dental floss rinse, mouthwash, or toothpick, but if you are unable to remove the debris, you can seek medical attention. The specific cleaning method can be chosen based on the size of the wisdom tooth cavity and the amount of food debris.
1. If there are food residues in the wisdom tooth cavity for a long time, it may cause wisdom tooth pericoronitis or other oral diseases. If the wisdom tooth cavity is small and the amount of food debris is relatively small, you can use a dental flosser to pressurize the rinse, which can make the food debris spit out with the mouthwash.
2. If the food debris is large, you can also use a toothpick to remove the food debris embedded in the cavity. If the food cannot be removed or the cavity is large, a professional should scrape the cavity with a sharp spoon and rinse it with hydrogen peroxide solution.
