If you had a tooth extracted on the lower back areas, it is possible that you may not regain full sensory feelings immediately. After 24 hours contact your Dentistand let him know your symptons. This will cause an aspirin burn and the pain will increase later. Take the aspirin, then place a nice compress on the cheek. The abscess is producing heat, therefore the cold compress will keep the swelling down and the inflammation in check.
Relief is only temporary.
Pick up the phone and schedule an appointment with your dentist.
