How come when I eat alot of sugar my tooth hurts?

When i eat sugars a lot and then I try to eat how come it hurts really bad?

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.
