How Long Does a Root Canal Take? Everything You Need to Know

If your dentist has told you that you need a root canal, the first thing you’ve probably thought is: “Is it going to hurt?” and the second, surely: “How long am I going to be in the chair?”. The good news is that no, it usually doesn’t hurt (even if the name is scary), and as for the time… it depends. We’ll tell you everything, no beating around the bush, so you arrive at the dental chair with a clear head and no nerves.

What is a root canal and when is it needed?

A root canal, also known as endodontic treatment, is a procedure carried out when the nerve of the tooth is damaged or infected. This can happen because of a deep cavity, a knock or a fracture.

In short, the inside of the tooth is cleaned, the nerve is removed and the space is sealed to prevent future infections. It’s a way of saving a tooth that would otherwise have to be extracted. And yes, it’s much better to keep the natural tooth whenever possible.

Factors that affect how long a root canal takes

OK, let’s get into it. How long does a root canal really take? Well… there’s no single answer, but we can explain what it depends on.

The complexity of the tooth being treated

A tooth with a single root, like the incisors, usually takes quite a bit less than a molar, which can have three or more canals. The more canals there are, the more time is needed to clean and seal them properly.

The dentist’s experience

The professional’s skill and experience also have an influence. An experienced endodontist can do the job faster and with greater precision, which is always appreciated when you’re sitting there with your mouth open thinking about anything else.

The clinic’s technology and equipment

The use of microscopes, apex locators and rotary systems makes the treatment more efficient and precise. In well-equipped clinics, the root canal is usually done in less time and with better results.

The average length of a root canal step by step

To give you a realistic idea, let’s break down how long each phase of the process can take.

First visit: diagnosis and assessment

Here the examination is done, X-rays are taken and it’s confirmed whether you really need a root canal. This usually takes around 20 to 30 minutes, depending on the case.

Root-canal treatment: how long does it take?

The treatment itself can last between 45 and 90 minutes per session, depending on the tooth and whether everything goes as it should. In more complex cases, a second visit may be needed to finish the work.

Review and follow-up afterwards

After the root canal, you may have to come back to fit a final crown or for a check-up. These visits are usually quicker, around 15 to 30 minutes at most.

Can a root canal be done in a single session?

Yes, in many cases everything can be done in a single session, especially if there’s no active infection or complications. But if there’s a lot of pain, pus, or the tooth is very inflamed, it may be better to split the treatment into two or three appointments to ensure proper healing.

And don’t worry, local anaesthetic is used throughout the procedure. You most likely won’t feel any pain, just a bit of pressure or tiredness from keeping your mouth open for a while.

Tips for a fast recovery after a root canal

After the treatment, it’s normal to feel some sensitivity or discomfort for a few days, but it’s usually easily controlled with common painkillers.

Here are some practical tips:

• Avoid chewing on the treated side for 24-48 hours.
• Don’t eat very hard or sticky foods until the final crown is fitted.
• Follow your dentist’s instructions and don’t skip the check-ups.
• If the pain increases or you notice swelling, see the dentist as soon as possible.

Frequently asked questions about root-canal treatment

Does a root canal hurt?

No. It’s done with local anaesthetic and is usually less uncomfortable than an extraction. The fear is common, but it’s quite far from today’s reality.

Can I work after having a root canal?

In most cases, yes. You may notice the area a little numb or somewhat sensitive, but nothing that stops you getting back to your daily routine.

How long does a tooth with a root canal last?

If the treatment is done well and protected with a crown, it can last a lifetime. But careful, that doesn’t mean it doesn’t need looking after. Hygiene and regular visits are still essential.

Conclusion: the time a root canal takes is worth it if it saves your tooth

Although it might sound long, a root canal isn’t as terrible as it seems. Between 45 and 90 minutes of treatment can save you a tooth and prevent bigger problems. What matters is going to a clinic you trust, following the instructions well and looking after your mouth after the procedure. Simple as that. And if you have any doubts, you know we’re here to help. Your peace of mind is as important as your dental health.
