After a wisdom tooth extraction, you should stick to soft foods until the area has healed. It is important to maintain a nutritious diet, however, as this will aid the healing process.
Blended soups are an ideal solution, as they provide plenty of vitamins and minerals, and enable you to eat vegetables without hard foods that may irritate or get lodged in the area of the surgery. Smoothies are great for the same reasons. Greek yogurt can also provide a great source of protein.
