How Long Does a Root Canal Take?

That deep, throbbing ache in your tooth can disrupt everything in your daily routine, from enjoying a meal to getting a good night’s sleep. When tooth pain goes from a minor annoyance to a constant problem, our team at Dow’s Lake Dental knows that you need a solution. Often, this kind of discomfort points to an issue deep inside the tooth, and root canal therapy may be the answer to get you feeling better.
You might picture a long, complicated appointment, but the reality is often much simpler. Most root canal procedures are completed in one or two appointments, with each visit typically lasting 90 minutes or less. The goal is to relieve your pain and save your natural tooth so you can get back to your routine without discomfort.
Why You Might Need a Root Canal
A root canal may become necessary when the soft tissue inside your tooth, called the pulp, becomes inflamed or infected. This can happen if a cavity is left untreated and decay reaches the tooth’s centre. It can also result from a crack or an injury that allows bacteria to enter.
Signs of a Tooth Infection
Your body is good at sending signals when something is wrong. An infected tooth often lets you know there’s a problem with a few distinct signs. You may notice:
- A constant, lingering toothache or a feeling of pressure
- Sharp sensitivity when you eat or drink something hot or cold
- Swollen, tender gums near the sore tooth
If your pain is sudden and severe, don’t wait. It could be a dental issue that requires emergency dental care to prevent complications.
The Root Canal Process Step-by-Step
Knowing what happens during a dental procedure can help you feel more comfortable. The process focuses on removing the source of the infection from your tooth’s inner anatomy and protecting it from future problems.
Here is an overview of the steps:
- Prepare the tooth: First, the area around your tooth is completely numbed. A small opening is then made to access the inside of the tooth.
- Clean the canals: The infected pulp is carefully removed from the inside of the tooth. The inner canals are then cleaned and shaped.
- Fill and seal: The clean canals are filled and sealed, and the access opening is restored with either a temporary or permanent filling, depending on the treatment plan.
How Long Does the Procedure Take
Some of our patients are surprised to learn that a root canal doesn’t have to take all day. This treatment is usually finished in one (sometimes two) visits to the dental office. Each appointment is designed to be efficient so you can get back to your life.
Factors That Affect the Timeline
While most procedures are quick, a few factors can affect the overall time. The length of your appointment can depend on:
- The location of the tooth
- The complexity of your tooth’s root system
- The extent of the infection inside the tooth
What to Expect After Your Root Canal
Once the procedure is complete, your tooth needs some time to heal. Recovery is usually straightforward, and following a few aftercare tips can help you stay comfortable. Any discomfort caused by the infection should be gone, but some tenderness or sensitivity is normal.
Immediate Aftercare Tips
For the first few days, it can help to be gentle with the treated tooth. Simple actions can make a big difference in your comfort. We often recommend:
Follow any specific instructions provided by our dental team
Avoid chewing directly on the treated tooth until it is fully restored with a dental crown, or until your dentist gives you the go-ahead
Stick to soft foods like yogurt, soup, or smoothies

How to Manage Discomfort
As the numbing agent wears off, you might feel some tenderness in the area. This is a normal part of the healing process. Your dentist in Ottawa can suggest simple options to help you manage any discomfort from tooth sensitivity while your mouth recovers.
Root Canal Myths & Facts
Root canals have a reputation for being scary, but most of what you hear is based on outdated information. Modern dental care has made the procedure a routine and comfortable way to fix a painful problem.
Myth: Root Canals Are Very Painful
The biggest myth is that the procedure itself hurts. In reality, a root canal is a pain-relief treatment. The infection or inflammation inside the tooth often causes the pain, and root canal treatment addresses the source of the problem. Because the area is numbed, you shouldn’t feel any pain during the procedure itself, so you can relax and let us take care of you.
Fact: A Root Canal Saves Your Natural Tooth
A root canal is not a major surgery: It’s a restorative treatment. It clears the infection and helps you keep your tooth, maintaining your natural smile and bite.
