You probably have an area of exposed dentin. This happens when you wear through the protective enamel. This is not uncommon for someone who is a grinder or an ice chewer. Your dentist can coat the tooth with a varnish to help with the symptoms. Sensitivity toothpaste also helps. Ultimately you should treat the cause if you are grinding consider a night guard. If you are chewing ice, stop. You might have a cavity on that tooth that the sugar gets into and irritates it, it might not be visible so go to a dentist! You fix it by going to a dentist. You have tooth decay and because of that the sugar is reaching the nerve.
