Root Canal Treatment
Root canal treatment is one of the most common dental procedures around, and when it is done right, it can save your tooth and stop pain for good.
- Removes the infected or damaged pulp from inside your tooth
- Cleans and shapes the root canals so bacteria cannot grow back
- Seals the tooth to protect it and keep it strong
- Can save a tooth that might otherwise need to be pulled out
With the right care after treatment, a root canal can help your tooth last for many years to come.
What Is Root Canal Treatment?
Root canal treatment (sometimes called endodontic treatment) is a way of fixing a tooth that has become infected or badly damaged on the inside. Inside every tooth there is a soft area called the pulp. The pulp holds nerves and blood vessels. When the pulp gets infected or damaged, it can cause a lot of pain and swelling.
A root canal removes the pulp, cleans the inside of the tooth, and then seals it up. Most people think root canals are scary, but the treatment is usually no more painful than getting a filling. In fact, it gets rid of the pain you already have.
The procedure is carried out by a dentist or a root canal specialist (called an endodontist). It normally takes one or two visits to complete.
What Root Canal Treatment Includes
When you come in for root canal treatment, here is what you can expect:
- A full check of the tooth using X-rays to see how much damage there is
- Local anaesthetic to numb the area so you do not feel pain during the treatment
- Removal of the infected or damaged pulp from inside the tooth
- Cleaning and shaping the root canals to clear out any bacteria
- Filling and sealing the canals with a special material called gutta-percha
- A filling or crown placed on top of the tooth to protect it and restore its shape
- Aftercare advice so your tooth heals well and stays healthy
Every tooth is different, so the number of visits and the time needed can vary. Your dentist will talk you through exactly what to expect before anything starts.

Why Is Root Canal Treatment Worth It?
A lot of people put off dental treatment because of cost or fear. But leaving an infected tooth without treatment can make things much worse.
Getting a root canal stops the infection from spreading to other teeth and your jaw. It gets rid of the pain and swelling caused by the damaged pulp, and it saves your natural tooth so you do not need an implant or denture. Keeping your natural teeth is almost always better for your long-term oral health, and the procedure has a very high success rate when done by a trained professional. With normal brushing and check-ups, a well-treated tooth can last a lifetime.
Losing a tooth might seem like a simple fix, but replacing it costs more and takes longer than saving it. Root canal treatment is one of the most cost-effective ways to protect your smile and your health.
If you are worried about the cost, ask your dentist about payment plans. Many practices offer flexible options to spread the price over time.
Root Canal Treatment FAQs
Is root canal treatment painful?
Root canal treatment is usually no more uncomfortable than having a filling. Local anaesthetic is used to numb the area completely, so you should not feel anything during the procedure. Any tenderness afterwards typically settles within a few days.
How long does root canal treatment take?
Most root canal treatments are completed in a single appointment lasting between 60 and 120 minutes. The exact time depends on which tooth is being treated and how complex the case is. Some teeth may require a second visit to fully complete the procedure.
What does root canal treatment involve?
Root canal treatment involves removing the infected or damaged pulp from inside the tooth, cleaning and shaping the root canals to eliminate bacteria, and sealing the tooth with a material called gutta-percha. A filling or crown is then placed on top to restore strength and protect the tooth long term.
Will I need a crown after root canal treatment?
In most cases, yes. A crown is recommended after root canal treatment to protect the tooth and prevent it from becoming brittle or cracking over time. Your dentist or endodontist will advise you on the best option for your particular tooth.
What happens if I leave an infected tooth untreated?
Without treatment, the infection can spread to surrounding teeth, gums, and jaw, causing significant pain and potentially becoming a serious health issue. In most cases the tooth will eventually need to be removed, which is more costly and complex than saving it with root canal treatment.
How long will a root canal treated tooth last?
With proper aftercare, a root canal treated tooth can last many years — often a lifetime. Good oral hygiene, regular brushing and flossing, and routine dental check-ups all help to keep the treated tooth healthy and strong.
What is the difference between a dentist and an endodontist?
While all dentists are trained to perform root canal treatment, an endodontist is a specialist who focuses exclusively on treating the inside of teeth. Endodontists receive additional postgraduate training and use advanced equipment, making them particularly well-suited to complex or difficult cases.
What are the signs that I might need root canal treatment?
Common signs include persistent toothache, sensitivity to hot or cold that does not ease, swelling or tenderness in the gum near a tooth, and visible darkening of the tooth. If you are experiencing any of these symptoms, it is important to book a dental appointment as soon as possible.
