Other forms: toothaches
A toothache is pain that you feel in your tooth or jaw, especially pain that lasts for a while. A cavity is one thing that can give you a bad toothache — so be sure to floss regularly.
Breaking a tooth on a hard piece of candy, grinding your teeth at night, not going to the dentist for months, or eating too soon after dental surgery — all of these can result in a toothache. There's also the short, sharp pain of biting into something cold, which is less likely to be described as a toothache. For a true toothache, it's usually a good idea to see a dentist.
