The choice between root canal treatment and extraction depends mainly on whether the tooth can be restored and kept healthy. If enough sound tooth structure, healthy gum and bone remain and the root is not cracked, saving the tooth is usually preferred. If it is split, too broken down or too loose, extraction is often wiser.
Two ways to deal with an infected tooth
When the pulp, the soft tissue inside a tooth that contains its nerve and blood vessels, becomes badly inflamed or infected, it cannot heal on its own. There are two ways to remove the problem: clean out the inside of the tooth and keep it, or remove the whole tooth.
Root canal treatment removes the damaged pulp, cleans and disinfects the narrow canals inside the roots, then fills and seals them. If you want to know what each appointment looks like, our guide on what happens during root canal treatment walks you through it. Extraction removes the tooth entirely, which ends the infection but leaves a gap.
Without treatment, an infected tooth rarely settles for good by itself. As the NHS explains, if an infected tooth is not root-treated, it may need to be taken out.
When saving the tooth is usually the better choice
Dentists generally try to keep natural teeth when this is realistic. A tooth is usually a good candidate for root canal treatment when:
- enough healthy tooth structure remains to rebuild it with a filling or a crown;
- the gum and bone around the root are healthy enough to hold it firmly;
- the root is not cracked or split;
- the canals can be reached and cleaned;
- the tooth matters for chewing or for your smile.
A tooth that hurts a lot can still be very saveable. The strength of the pain says little about whether a tooth can be kept; the examination does.
When extraction is often the wiser option
Sometimes keeping a tooth would mean a long, uncertain treatment with a poor chance of lasting. Extraction is usually recommended when:
- the root has a vertical crack, which generally cannot be repaired;
- decay has destroyed so much of the tooth, often below the gum line, that it cannot be rebuilt;
- advanced gum disease has destroyed much of the supporting bone and the tooth has become loose;
- a previous root canal treatment has failed and re-treatment is not possible or unlikely to succeed;
- it is a wisdom tooth with no useful role in chewing.
Some extractions are simple, while others need a small surgical step, for example when a tooth has broken at the gum line. Our article on simple and surgical extraction explains the difference.
How the dentist reaches a decision
The decision is made together with you, after a careful look at the tooth. In most cases this happens during one consultation:
- Your story: when the pain started, what triggers it, whether there has been swelling, and your general health and medicines.
- Clinical examination: checking the tooth, any filling or crown on it, the gum around it and how firm it is.
- Simple tests: gentle tapping, a cold test and measuring the gum pocket around the tooth help to show whether the pulp is alive and how healthy the support is.
- An X-ray: this shows the depth of the decay, the shape of the roots and any infection at the root tip.
- Discussion: the dentist explains the options, the realistic outlook of each and what would follow, so that you can choose.
Sometimes the answer only becomes clear once an old filling or the decay has been removed.
Root canal treatment and extraction side by side
| Point | Root canal treatment | Extraction |
|---|---|---|
| Visits | Usually one or two, each often 60 to 90 minutes | Usually one, often under an hour |
| Anaesthesia | Local anaesthesia; usually feels similar to a large filling | Local anaesthesia; you feel pressure but not sharp pain |
| Afterwards | Tenderness for a few days in most cases | Soreness and sometimes swelling for a few days; the gum heals over one to two weeks |
| What follows | Often a crown, especially on back teeth | A gap, which you may choose to fill |
A root-treated back tooth becomes more brittle, which is why a crown is often recommended after root canal treatment. When it is well sealed and protected, a root-treated tooth can last many years, often for life.
After an extraction: should the gap be filled?
After an extraction, the bone in that area slowly shrinks. Over time, neighbouring teeth can tilt into the space, and the opposing tooth may drift towards it. This does not happen to everyone at the same pace, but it is worth discussing before you decide.
The main ways to replace a missing tooth are a dental implant (a small titanium post placed in the bone that supports a crown), a bridge (a false tooth held by the teeth on either side) or a removable denture. Our patient guide to dental implants covers the first option in detail. For some back teeth, leaving the gap can also be acceptable; your dentist can tell you whether that applies to you.
What determines the cost
We do not quote a price without examining the tooth, because each situation is different. The main factors are:
- which tooth it is and how many canals it has (molars usually have more);
- whether it is a first treatment or a re-treatment;
- whether a crown or a post will be needed afterwards;
- whether the extraction is simple or surgical;
- whether, and how, you plan to replace the tooth afterwards.
When comparing options, it helps to look at the whole plan rather than the first step only. A consultation gives you a clear treatment plan for your tooth.

Frequently asked questions
My tooth has stopped hurting. Do I still need treatment?
Possibly, yes. Pain can stop because the nerve inside the tooth has died, not because the problem has gone away. A dead pulp can still be infected, and the infection may slowly affect the bone around the root tip, sometimes without symptoms for a while and sometimes with swelling later on. That is why a tooth that hurt badly and then went quiet should still be checked. An examination and an X-ray usually show whether there is an infection and whether the tooth can be saved with root canal treatment or is better removed.
Can antibiotics fix the tooth instead of a root canal or an extraction?
Not on their own. Antibiotics travel through the blood, and the inside of an infected tooth has lost its blood supply, so they cannot clean it out. The source of the infection remains, and symptoms usually come back once the tablets stop. Antibiotics are useful only in particular situations, for example when an infection is spreading with facial swelling or fever, and then alongside treatment of the tooth. Taking them repeatedly without treating the cause also contributes to antibiotic resistance. The lasting solution is to clean the tooth with root canal treatment or to remove it.
It is a back tooth nobody sees. Isn't it simpler to pull it?
Back teeth do most of the chewing, so losing one can affect how you eat, even if nobody notices it when you smile. Removing a tooth can also lead, over time, to neighbouring teeth shifting and the opposing tooth moving into the space. That said, extraction is a reasonable choice in some situations, and the decision is yours. The useful question is not only which option is simpler today, but which plan suits your mouth, your health and your budget over the coming years. Your dentist can set out both paths so that you can compare them calmly.
Can a tooth that already had a root canal be treated again?
Often, yes. If a root-treated tooth becomes painful or shows infection on an X-ray, sometimes years later, it may be possible to redo the treatment. This is called re-treatment: the old filling material is removed from the canals, which are then cleaned again and resealed. In some cases, a small surgical procedure at the tip of the root is another option. Whether re-treatment makes sense depends on the condition of the tooth, how well it can be rebuilt and why the first treatment did not last. When the outlook is poor, extraction may be advised instead.
How long can I wait before deciding?
It is fine to take a little time to think about your options, but an infected or deeply decayed tooth should not be left for months. Infection can spread, and decay can continue until a tooth that could have been saved becomes too damaged to keep. If you notice swelling of the face or jaw, fever, difficulty opening your mouth or difficulty swallowing, seek dental or medical care urgently. If you are unsure, a consultation lets the dentist assess how urgent your situation is and, when needed, relieve the pain while you decide.
Will I need to take time off work afterwards?
Most people return to their normal activities the same day or the next day after either treatment. After root canal treatment, the tooth may feel tender when biting for a few days, and simple painkillers are usually enough. After a simple extraction, you are advised to rest for the rest of the day, avoid rinsing hard, smoking and very hot drinks, and eat soft food on the other side. A surgical extraction can cause more swelling, so some people prefer to plan a quieter day or two. Your dentist will give you clear aftercare advice.
