How Long Does a Root Canal Take? Duration and What to Expect

 Having a toothache is no fun, especially when the pain is so bad it keeps you up at night. Often, this kind of severe pain means the inside of your tooth is infected. The good news is that a root canal treatment can fix this problem, get rid of the pain, and save your tooth.

But if you’ve never had one, a common question is: “How long does a root canal take?” The thought of sitting in the dentist’s chair for a long time can be a bit nerve-wracking. 

Don’t worry, we’re here to explain everything in plain language so you know exactly what to expect.

What is a Root Canal and Why is it Performed?

Imagine your tooth is like a little house. The hard, outer part is the walls, and the inside has a soft centre called the ‘pulp’. This pulp contains nerves, blood vessels, and connective tissue. It’s important when your tooth is growing, but once the tooth is fully grown, it can survive just fine without the pulp.

Sometimes, bacteria can get into this pulp. This usually happens because of a deep cavity, a crack in the tooth, or a serious injury. When the pulp gets infected, it swells up and causes a lot of pain. If left untreated, the infection can spread, and you could lose the tooth.

A root canal is a dental procedure to remove the infected pulp. It’s like a deep clean for the inside of your tooth. The dentist cleans out the infected area, seals it up, and puts a filling or a crown on top to protect it. This saves the tooth from needing to be pulled out.

How Long Does a Root Canal Procedure Usually Take?

This is the big question, and the answer isn’t a simple number. It really depends on the tooth and the complexity of the case.

For a simple case, a root canal on a front tooth or a premolar (the teeth in the middle of your mouth) can often be done in one sitting, lasting about 30 to 60 minutes.

However, a molar (the teeth at the back of your mouth) is a bit trickier. They have more roots and canals to clean out, so the procedure takes longer. A root canal on a molar will usually take 90 minutes or more, and might require two appointments.

A good rule of thumb is to expect the appointment to last anywhere from 30 minutes to a couple of hours. The dentist will be able to give you a more accurate idea of the root canal duration once they’ve had a look at your tooth.

The Steps Involved in a Root Canal Procedure

Let’s break down what happens during the procedure so you can understand why it takes the time it does.

  1. Anaesthetic: First, the dentist will numb the tooth and the surrounding area. This is a crucial step that ensures you experience no pain during the treatment. The dentist will wait a few minutes for the anaesthetic to fully kick in.

  2. Access: The dentist will make a small hole in the top of the tooth to access the pulp chamber and root canals.

  3. Cleaning and Shaping: This is the longest part of the root canal procedure. The dentist uses tiny, specialised tools to carefully remove all the infected pulp and clean out the inside of the tooth. They will also use special solutions to kill any remaining bacteria. This step takes time because the dentist needs to be very thorough to make sure the infection is completely gone.

  4. Filling the Canal: Once the canals are clean and dry, they are filled with a special rubber-like material called gutta-percha. This seals the canals and prevents any new bacteria from getting in.

  5. Sealing the Tooth: A temporary filling is placed on top of the tooth to protect it until a permanent filling or crown can be added. If a crown is needed, this will usually be done at a second appointment.

Why Does the Root Canal Take Time?

The reason a root canal can’t always be a super-quick job is all about thoroughness. The dentist needs to be absolutely certain that every single bit of infected tissue is removed and that the canals are completely disinfected.

  • Complexity of the Tooth: As mentioned before, some teeth are more complex than others. Molars have multiple roots with many tiny, winding canals. Finding and cleaning all of them takes a lot of time and skill.

  • Presence of Infection: If the infection is severe, it may take longer to thoroughly clean the tooth and ensure all bacteria are eliminated.

  • Anatomy of the Patient: Everyone’s teeth are a little different. The shape and size of your root canals can affect how long the procedure takes.

What to Expect Before, During, and After the Procedure

Before the Procedure

  • You’ll have a consultation with the dentist. They’ll take an X-ray to see the extent of the infection and the shape of your tooth’s roots.

  • They will discuss the treatment plan with you, including the root canal cost and how long they expect it to take.

  • Let the dentist know if you have any questions or concerns. A good dentist, like dentist Engadine, will be happy to answer them and make you feel at ease.

During the Procedure

  • You’ll be given a local anaesthetic, so the procedure should be pain-free.

  • You might hear some noises, like the whirring of the dentist’s drill, but it won’t hurt.

  • You’ll likely have a rubber dam placed around your tooth. This is a small sheet of rubber that isolates the tooth being worked on, keeping it dry and clean, and protecting you from any debris.

After the Procedure

  • You might feel some tenderness or mild pain for a few days after the procedure. This is normal and can usually be managed with over-the-counter pain medication.

  • Avoid chewing on the treated tooth until you get your permanent filling or crown.

  • The pain you had before the root canal should be gone, and you should start to feel much better.

How Long Does the Recovery Process Take?

The immediate recovery from a root canal is pretty quick. The numbness from the anaesthetic will wear off in a few hours.

The real recovery is about your body healing from the inflammation and the infection. This usually takes a few days. The mild soreness you might feel should go away within a week.

The most important part of the recovery process is protecting the tooth. The treated tooth is now more fragile. You need to follow the dentist’s instructions and get a permanent filling or crown put on as soon as possible. This is the final step to make sure your tooth is strong and healthy again.

Can a Root Canal Be Done in One Visit?

Yes, a root canal can often be done in a single visit. This is especially common for teeth with a single root, like the front teeth. A one-visit root canal is grand because it gets the job done quickly, and you don’t have to worry about a temporary filling for long.

However, sometimes a dentist might choose to do it in two visits. This could be because:

  • The infection is severe, and they need to make sure it’s completely cleared before filling the tooth. They might place a special medication inside the canal for a week to help kill the bacteria.

  • The tooth is a tricky molar with complex roots that need extra time to clean.

  • A crown needs to be made, and that requires a separate appointment.

So, while a one-visit root canal is a possibility, don’t be surprised if the dentist recommends two appointments. It’s all about doing the best job to save your tooth.

Conclusion

A root canal is a fantastic procedure that can save a tooth that would otherwise need to be pulled out. The question of “How long does a root canal take?” is a fair one, and we hope this has given you a clearer idea.

The duration can vary, but generally, you’re looking at a single appointment of 30-90 minutes or two appointments. The time spent is a small price to pay for getting rid of that awful toothache and keeping your natural smile.
