Watch and wait: If the wound is healing, you do not have pain, there is no bleeding or discharge, you may watch and wait. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.

Normal: As long as you have not problematic symptoms, you should be OK. If unsure, see the Dentist that did the extraction as post-surgical care is part of the service you are paying for.
