Persistent toothache and pain
How can you tell if you have a cavity? A toothache or severe pain often signal developing cavity symptoms, especially when the damaged tooth comes into contact with something. “Pain is often a symptom, and pain can be in the gums below the tooth or the tooth itself,” explains Eric Klein, DDM. “Sometimes you have a sharp, acute pain or it may be a dull, throbbing pain, and both are signs of a cavity.”
Pain when chewing on food
“If you start chewing on any food and something hurts, it could be because the tooth has a crack in it or because the tooth has a cavity,” says Dr. Klein. If you feel a sharp, sudden pain after biting into an apple or chewing on food, the nerve in your tooth may be infected and in the process of decaying. Touching the afflicted area can help you gauge the severity of your pain and decide whether or not the tooth needs to be evaluated. If you can’t touch your tooth without shuddering in pain, schedule an appointment with your dentist to have the tooth examined. Here are some home remedies for toothaches you can try until you can get to a dentist.
