Root Canal - Dr. Wong

What is a root canal?

A root canal is a procedure that removes infected pulp from inside your tooth. Your dentist cleans and seals the canals to prevent further damage and save your tooth. You might need root canal treatment if bacteria reach the pulp and cause pain or inflammation.

This can happen if:

You have a deep cavity
You crack a tooth

Root canals are common. Good oral hygiene can help you avoid needing one.

What to Expect at Root Canal Appointments

Your dentist or endodontist will:

Numb the area with anesthesia (if you’re nervous, you may get medication to help you relax, and you might be drowsy after)
Place cotton or a dental dam to keep the area clean and dry during the procedure
Create a small hole in your tooth’s crown to reach the pulp
Remove the infected pulp using tiny tools
Clean and disinfect the inside of the tooth
Fill the empty space with a rubbery dental material (gutta-percha)
Seal the tooth with a temporary filling
Place a permanent crown (usually at a later visit) to protect your tooth and restore your bite

Most root canals take about 60 to 90 minutes. Some may require more than one visit.

Recovery and Outlook

How long does root canal recovery take?

Most people recover in less than a week. You might have some lingering sensitivity, but you shouldn’t have pain that lasts longer than that. If you do, call your provider.

How can I support healing?

Good care helps with root canal recovery. These simple steps can support your healing and help you avoid complications:

Avoid smoking — it can slow healing.
Brush after meals and floss once a day.
Don’t chew on the treated tooth until your permanent crown is placed.
Eat soft foods for a few days, like mashed potatoes, yogurt, smoothies or well-cooked pasta.
Use an antibacterial mouthwash to keep germs away.
