Root Canal: What to Expect

Modern root canal treatment is comfortable, effective, and saves teeth

BluSky Bee

Root canals have an unfair reputation. Modern root canal treatment is comfortable, effective, and saves teeth that would otherwise need extraction. Here's exactly what to expect, step by step.

Before Your Appointment

Diagnosis

First, we confirm a root canal is needed:

  • Symptoms: Pain, sensitivity, swelling, darkening tooth
  • X-rays: Show infection at tooth root
  • Testing: Determine if nerve is healthy or damaged

What You'll Learn

At your consultation, we'll explain:

  • Why root canal is recommended
  • What the procedure involves
  • Timeline and number of visits
  • Costs and insurance coverage
  • Post-treatment restoration needs

Preparing

  • Take any prescribed antibiotics as directed
  • Eat normally before your appointment
  • Take over-the-counter pain reliever if recommended
  • Arrange a ride if you're having sedation

During the Procedure

Step 1: Getting Comfortable

Local anesthesia: We thoroughly numb the tooth and surrounding area. You shouldn't feel pain—just pressure and vibration.

Sedation (optional): Nervous? Nitrous oxide, oral sedation, or IV sedation are available.

Rubber dam: A small sheet isolates the tooth, keeping it clean and dry.

Step 2: Accessing the Tooth

We create a small opening in the top of the tooth to reach the pulp chamber and root canals. You may feel pressure but shouldn't feel pain.

Step 3: Removing Infected Tissue

Using tiny specialized instruments:

  • Infected or dead pulp tissue is removed
  • Root canals are cleaned and shaped
  • Bacteria and debris are flushed out

With microscope: At our Holland Cross and McCarthy locations, microscope magnification allows us to see and clean canals more thoroughly.

Step 4: Cleaning and Shaping

Each canal is:

  • Shaped to proper dimensions
  • Irrigated with antibacterial solutions
  • Dried and prepared for filling

This is often the longest part of the procedure.

Step 5: Filling the Canals

Cleaned canals are filled with:

  • Gutta-percha: Rubber-like material that seals the canals
  • Sealer: Cement that ensures complete seal

The goal: eliminate all space where bacteria could survive.

Step 6: Temporary Restoration

The access opening is sealed with temporary filling material. You'll return for a permanent crown.

How Long Does It Take?

Tooth Type Typical Duration
Front tooth (1 canal) 45-60 minutes
Premolar (1-2 canals) 60-75 minutes
Molar (3-4 canals) 75-90 minutes

Complex cases may require additional time or multiple visits.

After Your Root Canal

Immediately After

  • Numbness lasts 2-4 hours
  • Avoid eating until numbness wears off
  • Some tenderness is normal
  • Take pain medication as directed

First Few Days

What to Expect:

  • Mild to moderate discomfort (usually manageable with OTC pain relievers)
  • Tenderness when biting
  • Possible jaw soreness from keeping mouth open

Normal:

  • Discomfort for 3-5 days
  • Some sensitivity when chewing

Contact us if:

  • Severe pain not relieved by medication
  • Visible swelling
  • Allergic reaction to medication
  • Original symptoms return

Pain Management

Most patients manage discomfort with:

  • Ibuprofen (Advil) or acetaminophen (Tylenol)
  • Ice pack on cheek (20 minutes on/off)
  • Avoiding chewing on treated tooth

Prescription pain medication is rarely needed.

Getting Your Crown

Why You Need a Crown

Root canal-treated teeth are more brittle because:

  • Nerve and blood supply removed
  • Access opening weakens tooth structure
  • Tooth can crack without protection

A crown covers and protects the entire tooth.

Timeline

Step When
Root canal completed Day 0
Crown appointment 1-2 weeks later
Permanent crown placed Same day (with CAD/CAM) or 2-3 weeks later

Don't delay the crown. Teeth can fracture without permanent restoration.

Frequently Asked Questions

Not with modern techniques. Local anesthesia ensures you're numb. Most patients say it's similar to getting a filling. The reputation for pain comes from before modern anesthesia—and from the pain that brings people in for treatment.

Very successful—95%+ success rate. Most root canal-treated teeth last many years, often a lifetime with proper care.

Extraction is an option, but: saving natural teeth is almost always preferable; extraction requires replacement (implant, bridge, partial); root canal + crown often costs less than extraction + implant; your natural tooth is the best tooth.

Rarely. Failure can occur if: infection wasn't completely eliminated, tooth cracks, new decay develops, or canal anatomy was complex. Retreatment or surgery can often save the tooth.

Usually 1-2 visits for the root canal itself, plus 1-2 visits for the crown. Simple cases can sometimes be completed in one appointment.
