Getting to the Root of Endodontics

Endodontics. From the Greek endo (inside) and odons (tooth). Inside the tooth. And what's inside the tooth? Pulp, which contains the nerves, arteries and veins for each tooth, and tissue, which surrounds the root of the tooth.

Also synonymous with Endodontics is the term "root canal". The term "root canal" seems to instill fear into the hearts of anyone that hears it from their dentist. But is that fear really all that necessary? Let's break it down and see if all that fear is really warranted.

What is a Root Canal?

Teeth can have between one and four canals. If you looked at a side view of half a molar, you would see two canals - one on each side going up from the root to the top of the tooth. As noted, these canals are the pathways for the nerves, veins and other tissue that keep the tooth alive. A root canal becomes necessary when a tooth is damaged.

When is a Root Canal Needed?

A root canal is needed when a tooth becomes damaged due to decay or infection. If a cavity is not caught in time, the decay can move deep into the tooth and cause serious damage to the pulp and tissue. To prevent further problems to the already damaged tooth, or those surrounding it, the bad areas of the tooth need to be removed and repaired. The proper term for this procedure is , but most people just call it a root canal.

What Happens During the Endodontic Therapy?

The procedure is pretty simple. After applying the requisite anesthetic to numb your mouth, the dentist removes the damaged part of the tooth as far down as necessary. Once all the damaged and contaminated elements are cleaned out, the tooth - now dead - is filled with a dental composite. This composite helps keep the tooth in place. A dental crown is then fitted and attached to the top of the tooth. The dental crown restores the stability and natural look of the tooth.

It is true that dental instruments, such as tiny drills and files, are used during this process. While you won't feel any of the work being done on your teeth, the sounds or general knowledge of what's happening may still be a problem for you. In those cases, many dentists now offer sedation dentistry, so you can sleep lightly through the entire process.

When broken down, Endodontic Therapy isn't that big a deal, really. It is just a common procedure that helps improve your oral hygiene and allows you eat, drink and talk without pain again. Certainly nothing to be afraid of.
