Root Canal Q & A

What is a root canal?

A root canal is an endodontic treatment that removes decay from the pulpy interior of your tooth. Root canals repair severely damaged or decayed teeth, often preventing extractions or tooth loss. Like traditional cavity fillings, a root canal removes damaged or decayed tissue, and then your tooth is filled and sealed to prevent future damage.

Why would I need a root canal?

When your tooth becomes severely decayed or damaged, a root canal may be the only way to save it. The pulpy interior of your tooth holds the nerves and blood vessels that keep your teeth healthy and strong. If those nerves and vessels are damaged, your tooth could die, turn dark, and eventually fall out.

It’s more common for decay to reach the interior of your tooth if the tooth is cracked or damaged, allowing debris to work its way inside the tooth. A deep cavity can also reach the pulpy interior.

What are signs that I need a root canal?

There are a number of signs that you need a root canal including:

  • Toothache
  • Temperature sensitivity
  • Tenderness to touch
  • Swollen lymph nodes under your chin
  • Pain and swelling in surrounding gum tissue

In some cases, you may not have any symptoms at all. That’s why it’s critical to have regular dental checkups and X-rays to allow Dr. Kabiri to monitor the health of your teeth.

What happens during a root canal?

During a root canal, Dr. Kabiri thoroughly numbs your tooth and the surrounding tissue. Then using special tools, she creates an opening and removes the decayed tissue from your tooth, clearing away any debris. After removing the decay and ensuring the interior of your tooth is clean, she carefully fills your tooth and seals it to prevent future decay. If your tooth is weakened, Dr. Kabiri fits you with a crown to provide additional support and strength.


After a root canal, you continue to brush and floss your teeth. You may experience some tenderness following your treatment, but it should easily resolve with over-the-counter painkillers or an ice pack.

You need to have follow-up appointments so Dr. Kabiri can check that the root canal procedure was effective. These appointments also allow her to ensure that your other teeth remain healthy and strong.
