If your surgeon closed the wounds with stitches, food won't be able to get in the holes. You may see particles near the extraction sites that look grey, black, blue, green, or yellow. This is normal discoloration and is part of the healing process. Thoroughly brush and floss the rest of your mouth, but avoid the teeth closest to the wound. It's okay to rinse the first day, but you have to take certain precautions.  Combine 1/4 teaspoon salt with one cup of warm water. Stir it well to mix. Avoid swishing the saltwater rinse in your mouth or spitting it out. Gently move your head to move the rinse around your mouth or use your tongue to help move the saline solution around. After rinsing, lean over the sink and open your mouth to let the rinse fall out. Don't spit. Your doctor may also give you chlorhexidine gluconate (Peridex, Periogard) to rinse with. This is a germicidal mouthwash that helps kill bacteria. Try diluting it with water at a 1:1 ratio to avoid any possible negative effects of the chlorhexidine. Don't use your tongue to prod the hole, either. Doing this may introduce bacteria to the wound, and could disrupt the healing tissue. Instead, stick to salt water rinses to remove food particles. Any kind of suction activity in the mouth could dislodge blood clots, causing a painful dry socket and potentially leading to infection.
