Eating with a numb mouth can be dangerous, so don’t eat until the anesthesia has worn off enough that you can feel your cheeks and tongue. Otherwise, you might give yourself a serious bite injury accidentally.
On the day of surgery, you should eat only soft foods. This is not the same as a liquid diet and may include foods like bananas, yogurt, and soup. Don’t drink any alcohol for 48 hours after surgery. Avoid foods that can break into fragments that get into your wound. This includes potato chips, corn chips, crackers, and nuts.
Even if you have a provisional crown, bridge, or denture, don’t resume chewing immediately. When possible, try to avoid chewing with the new implant. Use caution with hot liquids at first until you’re confident you can handle them safely. Other than fragmentable food, you can return to eating normally as soon as you feel up to it.
