Has a dentist ever looked at an x-ray of your teeth and recommended a root canal? You probably know that root canals are performed to remove aggravated (and painful) tooth nerves. Why would a dentist want to do this procedure on a tooth that has never bothered you? The truth is that root canals are often used to protect teeth with "dead" nerves from future pain and infection. Take a look!
A root canal is a dental procedure where the nerve of the tooth is removed and the resulting empty nerve canal is filled with a sealing material. They are performed on teeth with some type of irreversible nerve damage. This typically stems from bacteria, trauma or deep/extensive dental work. Patients may complain of a painful tooth that throbs or has an exaggerated reaction to cold foods/drinks. These can be clues that the nerve has become so severely agitated that it will eventually wither out and die. Conversely, a patient can indicate that the gums around the tooth are swollen, the tooth is sensitive to biting or that there is a bump or pimple on the gums above a tooth. These types of findings suggest the nerve in the tooth has already died, and is now fueling a localized bacterial infection called an abscess. Either way, these types of teeth will eventually need root canals to solve their issues.
Why might you need a root canal on a tooth that has never bothered you? A certain portion of the population will have the nerve in a tooth die in response to bacteria or trauma without pain or swelling. These teeth are usually discovered incidentally at a dental exam by visualizing an abscess on an x-ray. In most instances, this does not pose an emergency or cause for immediate concern. However, leaving the problem long term can lead to swelling, pain or the spread of infection.
