Root Canals Q&A

What are root canals?

A root canal involves removing the soft pulp from the inside of a damaged or infected tooth. The pulp is soft tissue, including blood vessels and nerve fibers, that’s prone to inflammation, which can cause immense tooth pain and lead to serious complications like tooth abscesses. 

A root canal stands out as an effective treatment for tooth inflammation or tooth infections because it allows you to keep your natural tooth. If you get a root canal for a molar or any of the teeth in your mouth that withstand lots of pressure from chewing, you need to get a crown after treatment to keep the tooth as strong as possible. 

What happens during root canals?

A root canal is a four-step treatment process. During your root canal at Pemberton Dental Associates, you can expect:


Anesthesia keeps your tooth and a margin of surrounding space numb for the root canal procedure. Your dentist first places a bit of numbing gel directly on the gums. Once it takes effect, they inject local anesthesia into the region. 

Pulp removal

Perhaps the most important part of a root canal is pulp removal. Your dentist creates a small hole in your tooth’s chewing surface and removes the pulp through it with tools called files. Once the inside of the tooth is empty, your dentist sanitizes the vacant canals. 


Your dentist coats the inside of your empty tooth with antibiotics, which kill any remaining infectious bacteria. You might also have to take oral antibiotics after the procedure. 

A temporary filling

Your dentist fills the cavities within the tooth with a rubbery material called gutta-percha before sealing the hole in the chewing surface. 

A restoration

In most cases, you need a crown to reinforce a tooth after a root canal. The CEREC® system with computer-aided design and manufacturing technology can make you a crown that fits perfectly and looks stunning in just a day. 

What are some signs I need a root canal?

The signs and symptoms of needing a root canal are similar to those of other dental complications, so you should come in for a diagnosis at Pemberton Dental Associates when you notice them. Emergency dentistry appointments are available when your symptoms are severe.

You might need a root canal if you experience:

  • Sharp pain from a tooth when biting down
  • Gum swelling 
  • Tooth sensitivity
  • Visible damage to a tooth
  • Darkening gums
  • Pimples on your gums

Your dentist examines you and can tell pretty quickly whether or not a root canal benefits you.
