I have nerve exposed with severe tooth pain?

See dentist: It would be prudent to see your dentist at your earliest. You may take an over the counter pain medication in the mean time.

Exposed Nerve: If the nerve is truly exposed, you either need root canal therapy or an extraction. Not much else one can do. Please see a local dentist.

Can't: Can't fix this over the computer, or with pills, poultices, salves, rinses, or snake oil. You have a virulent infection that is now spreading to other organ systems vie your circulatory system. You need immediate hands-on dental treatment. Nothing else will work. Please call Dentist for emergency appointment.

Exposed nerve: You need to see a dentist if your tooth is broken and the nerve is exposed. This will not heal on its own. You will need a root canal to save your tooth

Root canal: you desperately need a root canal,like yesterday. See a dentists immediately and get them to send you to a endodontist.
