By teeth sensitivity I mean that a tooth is painful because of a stimulus. A toothache is tooth pain that doesn’t require an outside stimulus—it just hurts. But if your tooth reacts to cold, chewing, air, or some other stimulus, that is called sensitivity.
A toothache almost certainly needs treatment. Sensitivity may or may not need treatment, depending on the cause. To help you with this, I have written a number of pages explaining the various types of sensitivity, hopefully helping you know when you need to see your dentist and what to expect when you do.
