Food that gets caught in a wisdom teeth wound may be uncomfortable, but it alone should not cause an infection. Healing can still take place even if food gets caught, and it's more important to avoid touching or probing the wound. Clots in the gums may appear gray and fibrous, like food particles. Cleaning too vigorously in this case may remove the clot and cause further complications. This is especially important during the first 24 hours after surgery. Gradually move from soft foods to semi-soft foods as your wound heals. It's generally best to avoid hard, chewy, crunchy, and spicy foods, as these are most prone to pooling in the socket and causing irritation or infection.  Chew on the opposite side or your mouth from the extraction site. Avoid eating foods that are too hot or cold foods. Go for room temperature foods during the first two days. Wash your hands frequently with soap and water. Don't shake hands with people for a week or so. Don't share toothbrushes or other implements with others. You want to make sure that you don't pick up a secondary infection that could tax your immune system. Some bleeding will be common over the first few days following a tooth extraction. If you experience any of the following symptoms, however, you should contact your dentist or oral surgeon immediately.  Excessive bleeding (more than a slow ooze) Pus in the wound Difficulty swallowing/breathing Fever Swelling that increases after two or three days Blood or pus in nasal mucus Throbbing, dull pain after the first 48 hours Bad breath after three days Pain that is not reduced after taking painkillers
