What to Know Before You Sit in the Chair
You’ve heard the words “root canal” and felt your stomach drop. That reaction is common, but it’s usually based on old stories rather than what the procedure is like today. Modern dentistry has changed significantly, and most people are surprised by how straightforward their appointment turns out to be.
For most people, a root canal takes 60 to 90 minutes and wraps up in a single visit. Knowing what to expect can make the whole experience feel a lot less daunting.
At McKenzie Towne Family Dental, we’ve been performing root canals for over 24 years. We want you to feel informed before the procedure, and comfortable during it.
What a Root Canal Involves
Inside every tooth is a soft layer called the pulp, which contains nerves and blood vessels. When that pulp gets infected or inflamed from decay or damage, it can cause serious pain and put the tooth at risk. A root canal removes infected pulp, cleans out the canals inside the tooth root, and then seals everything up to protect the tooth going forward.
The goal is to save your natural tooth rather than remove it. Keeping your original tooth intact is almost always the better path for your bite, your jaw health, and your long-term comfort. The root canal therapy process at McKenzie Towne Family Dental is designed with exactly that in mind.
How Long the Procedure Takes
Typical Time for Most Teeth
Most root canals take between 60 and 90 minutes from start to finish. Procedures for front teeth and premolars tend to go faster, however, as these teeth have fewer canals. Many patients get everything done in one appointment and leave the same day with their tooth cleaned, sealed, and protected.
When It Takes Longer
Not every root canal follows the same timeline, and that’s completely normal.
- Molars have more canals, sometimes 3 or 4, which adds time to the cleaning process
- A severe infection may require the placement of a medicated dressing first, with the final seal completed at a second appointment
- Curved or very narrow canals require extra care and precision to treat properly
If your dentist mentions a second visit, it’s likely not a complication. It’s likely just the treatment being done carefully and thoroughly. Understanding how infection and decay affect tooth structure can help put your timeline into perspective.
What Happens Step by Step
Before the Work Begins
The appointment starts with X-rays so that your dental team can see the shape of the root and assess the extent of the infection. Digital X-rays make this step faster and more comfortable than older film-based methods.
Next, a local anaesthetic is applied to numb the area completely. Most people feel a small pinch from the freezing, but after that, the tooth itself should feel nothing at all.
During the Procedure
Once the area is numb, your dentist makes a small opening in the top of the tooth to reach the pulp chamber. The infected pulp is removed, and each canal is carefully cleaned and shaped. After the canals are flushed and dried, they’re sealed with a filling material to block out bacteria.
Depending on your situation, the dentist places either a temporary or permanent filling to close the tooth. You’ll typically receive instructions about a crown at this point too, which is discussed more below.t
Recovery & What to Expect After
Once the freezing wears off, some mild soreness or tenderness around the treated tooth is completely normal and usually fades within a few days.
- Stick to soft foods on the treated side while things settle down
- Over-the-counter pain relievers can help manage any discomfort in the first day or two
- Reach out to your dental team if swelling, significant pain, or pressure lingers beyond a few days

Common Root Canal Questions & Myths
Is a Root Canal Painful?
This is the big one. The honest answer is that, with local anaesthetic, the procedure feels very similar to getting a filling. You might feel some pressure, but sharp pain isn’t part of the process. However, it’s important to remember that a root canal relieves pain caused by an infection. For patients who feel anxious about dental procedures, oral and IV sedation options are available to help you stay comfortable throughout.
Do You Need a Crown After a Root Canal?
Back teeth like molars take on a lot of chewing force, and a treated tooth can become weaker over time without extra support. A dental crown helps protect your tooth and keeps it functional for years to come. Crown placement is usually scheduled as a separate follow-up visit after the root canal heals.
