One of the most painful procedures is tooth removal, especially when it has to involve cutting part of the gum or jaw. Then again, the dentistry procedure is executed using local anaesthesia, and sometimes general anaesthesia, so patients are safe. Because healing takes a certain amount of time, pain is felt soon after the appointment is over and continually. OTC pain killers can help mitigate that. Ask your doctor about the best medication to take during this period.
