Root canal vs extraction? How to choose the right option for your tooth

When tooth pain strikes or your dentist finds an issue on an X-ray, you might be faced with a difficult decision: root canal or extraction? Both treatments are common and can bring relief—but they come with different outcomes, long-term considerations, and impacts on your dental health.

At Rumney Endodontics in Cardiff, we regularly help patients decide on the best course of action based on the condition of their tooth, their overall oral health, and their personal goals. Here’s what you need to know about root canal vs extraction—and why preserving your natural tooth is often the healthiest choice.

What is a root canal?

Root canal treatment, also known as endodontic therapy, is a procedure used to save a damaged or infected tooth. It involves cleaning and disinfecting the inside of the tooth (the pulp chamber and canals), then sealing it to prevent future infection.

A root canal is typically recommended when:

• The inner pulp of the tooth is infected or inflamed

• There is a deep cavity that has reached the nerve

• The tooth has suffered trauma or repeated dental procedures

• There is a crack or chip that has affected the pulp

At Rumney Endodontics, our specialist team uses high-powered microscopes, digital imaging, and years of clinical experience to carry out root canals with precision, ensuring minimal discomfort and long-lasting results.

What is a dental extraction?

Extraction means removing the entire tooth from its socket. It may be necessary if the tooth is too damaged to repair or if there’s advanced bone loss due to gum disease.

A dentist may recommend extraction when:

• The tooth is fractured below the gumline

• Severe decay has left too little structure to restore

• Infection has spread beyond the root and cannot be resolved

• The tooth is causing crowding or is impacted

Extractions may seem simpler in the short term, but removing a tooth creates an empty space that must be managed with options like bridges, dentures, or implants. Without replacement, neighbouring teeth can shift, causing misalignment and bite problems.

Root canal vs extraction: what are the pros and cons?

Here’s a closer look at how the two treatments compare:

Root canal:

• Preserves your natural tooth

• Maintains jawbone strength and alignment

• Generally less invasive in the long run

• High success rate, especially with specialist care

Extraction:

• Fast removal of pain and infection

• Suitable if the tooth is unsalvageable

• No further treatment needed if the gap is left

As a general rule, saving a tooth is better than removing it whenever possible. Your natural teeth are designed to function with your bite and bone structure—and modern root canal techniques mean they can often be saved, even in complex cases.

Why choose Rumney Endodontics for root canal treatment?

At Rumney Endodontics, we’re not just a general Cardiff dental practice. We are a specialist-led clinic, welcoming patients from across South Wales for complex endodontic treatment. Dr Andrew Bartley and Dr Cassandra Maunder are both GDC-registered specialists in endodontics, with years of experience managing challenging cases.

We use advanced technologies like:

• Dental operating microscopes

If you’ve been told you may need a root canal or extraction, we’re happy to offer a second opinion or see you on referral from your dentist.

What happens if you do need an extraction?

If a tooth truly can’t be saved, extraction may be the right choice. In this case, we’ll ensure your care continues seamlessly with the right guidance on:

• Pain management and recovery

• Whether and when to replace the tooth

• How to protect the surrounding teeth and gum

We can also refer you for implants or prosthetic options if needed—and keep your dentist updated every step of the way.

The bottom line: don’t delay

Tooth pain, swelling, or a deep cavity should never be ignored. The sooner we see the tooth, the more likely we can save it with a root canal.

The longer you wait, the higher the risk of spreading infection, needing an extraction, or facing more invasive and costly treatment later on.

That’s why we encourage patients to get in touch as early as possible. If you’re unsure whether you need root canal vs extraction, our team will carry out a detailed examination and talk you through the options clearly—without pressure or jargon.
