Generally, don't brush your teeth and gargle within 24 hours after tooth extraction, and don't eat too hot food. It is normal for the wound to have a little bloodshot within 48 hours, but when a large amount of blood clots appear, you should go to the hospital to see a doctor in time.
You can also use wet and cold towels or ice packs and ice cubes at home to relieve toothache on your cheeks.
