What to Know About Root Canals
Do you need a root canal? Root canals often get a bad rap, but they are more common than you think! To prepare yourself, learn what you can about endodontic therapy before and during your dental visit. We can help!
Here’s what you need to know about root canals.
What Is a Root Canal?
A root canal is a natural, pulp-filled area at the root of the tooth. During root canal treatment (also known as endodontic therapy), your dentist removes the nerve and pulp of your tooth and cleans it out. Once this is done, the tooth is sealed.
When Is a Root Canal Done?
When a tooth is badly decayed or infected, a root canal may be the best way to save it and prevent the infection from spreading to surrounding teeth.
Where Is a Root Canal Treated on a Tooth?
There are three “sections” of teeth where root canal treatments are used:
Front Teeth (Anterior)
Side Teeth (Bicuspid)
Back Teeth (Molar)
The larger the tooth, the more “root canals” it has, which is why some people may need multiple root canal treatments on their back teeth. Larger teeth have a higher number of root canals and thus greater potential for infection.
Front Teeth
Front teeth usually have a single root containing one root canal.
Back Teeth
Back teeth usually have two or three roots, each containing either one or two root canals. Therefore, the farther back in the mouth the tooth is, the more work that needs to be done per tooth. Consequently, this makes root canals more expensive on back teeth than on front teeth.
How Do Root Canals Work (Root Canal Process)?
Steps of root canal treatment include:
Dental X-Rays
Local Anesthesia
Remove Bacteria and Decay
Seal the Tooth
Place the Crown
1. Dental X-Rays
Dentists use dental x-rays to see the shape of the root canals and determine if there are any signs of infection.
2. Local Anesthesia
Local anesthesia is used to numb the area near the tooth. It may not always be necessary since the nerve is already dead, but dentists often anesthetize the area to make patients feel more relaxed.
3. Remove Bacteria and Decay
Bacteria and decayed nerve tissue is removed from the tooth after an access hole is drilled into the tooth and pulp.
4. Seal the Tooth
Your dentist decides to either seal the tooth that day or put medication in the hole and wait a few days for the medication to heal the tooth.
5. Place the Crown (optional)
The tooth may or may not need a dental crown after the root canal to further secure it
