Toothaches are a vivid reminder that teeth aren't just pieces of hard tissue floating around in the gums. They are intricately formed sensory organs with layers of dentin and enamel protecting a living pulp. Coursing through the tooth's pulp is a vital bundle of nerves and blood vessels providing nutrients and sensation to each tooth. As long as the pulp stays healthy, you're rarely aware of the systems at work.
Tooth pain can be especially alarming, but it's meant to warn you that something's not right. Pain tells us that the bundle of nerves and vessels inside your tooth is irritated, damaged, or under attack.
A deep cavity can give bacteria access to the inner nerve bundle. In some cases, a significant infection, called an abscess, may develop in your jaw without any symptoms at all. Your dentist may suggest a root canal if we determine that the nerve won’t recover or if an infection present.
