Root Canals
Toothaches provide a vivid reminder that teeth aren’t just inert pieces of hard tissue floating in the gums. Instead, they’re intricately formed parts with layers of hard substances overlaying a delicate core. Coursing through the tooth’s center, this vital bundle of nerves and blood vessels provides nutrients and sensation to each tooth. As long as the tooth stays healthy, you’re rarely aware of the systems at work.

But pain rapidly changes your awareness in any part of the body. Tooth pain can be especially alarming, and 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. A crack extending into the same region can create stress that will need additional care to relieve. In some cases, a significant infection may develop in your jaw without any symptoms at all. If we determine that the nerve won’t recover or infection is present, then root canal treatment may be suggested.
Modern anesthetics provide powerful numbing for gentle removal of the inflamed nerve inside the tooth. The nerve canal undergoes disinfection and careful shaping, and a sealer fills the internal space. A filling or crown over the tooth helps return the tooth to its original condition.
But Are They Safe?
Internet articles continue to circulate claiming adverse health effects from root canals, despite years of research proving otherwise. Many of these claims rest on unsubstantiated theories put forward decades ago without any scientific basis. They’ve been thoroughly debunked by the most credible sources, supported by unbiased research projects. In fact, one popular Facebook article sounding a false alarm shakily rests on a 100-year-old study tossed aside long ago.
Professional organizations routinely review a broad range of research projects throughout the world. The American Association of Endodontists stays abreast of all the current and past research and can clearly support the safety of this vital service. In fact, new techniques and materials make root canal treatment more successful than ever. However, even older methods still hold a proven track record, allowing millions of damaged teeth to continue functioning.

Frequently Asked Questions
Do root canals hurt?
No, modern root canals are virtually painless thanks to advanced techniques and local anesthesia. Most patients report that the experience is similar to getting a filling, with minimal discomfort during and after the procedure.
How do I know if I need a root canal?
Common signs include severe tooth pain, prolonged sensitivity to hot or cold, swelling, or a pimple-like bump on the gums. If you have any of these symptoms, it’s important to see a dentist as soon as possible to prevent further infection.
What happens during a root canal?
The dentist removes the infected pulp, cleans and disinfects the inside of the tooth, and then fills and seals it. In most cases, a crown is placed afterward to restore strength and function.
How long does a root canal last?
With proper care, a root canal-treated tooth can last a lifetime. Good oral hygiene and regular dental visits help ensure its longevity, especially if the tooth has been restored with a crown.
