If the tooth can be saved, a root canal is usually the better long-term choice, because keeping your natural tooth protects your bite, your jawbone, and the teeth around it. Pulling the tooth makes more sense when it’s cracked below the gum, has very little healthy structure left, or has advanced bone loss around it. Needing to make this decision is common, and neither option is dangerous in trained hands. The key is an honest assessment of whether that specific tooth is restorable, which is exactly what a root canal consultation looks at.
Most people asking this question are in pain and want it gone. Fast. Extraction sounds quicker and cheaper on the day. But the real comparison includes what happens to the gap over the next 5, 10, and 20 years.
There are cases where a tooth extraction is the smarter move, and a good dentist will say so plainly. If you’re dealing with swelling or a throbbing ache tonight, the first step is calming the infection through an emergency dental clinic visit, and the bigger decision can follow once you’re comfortable.
And if extraction does happen, replacement options range from implants to bridges to dentures. You can find the team at Richmond Hill Smile Centre on Google Maps if you’d like an in-person opinion on your specific tooth.
What does a root canal actually do?
A root canal (endodontic treatment) removes the infected or inflamed pulp from inside the tooth. The pulp is the soft tissue that holds the nerve and blood vessels.
Here’s the process in plain terms:
- The tooth is numbed with local anaesthetic.
- A small opening is made in the top of the tooth.
- The infected pulp is removed with fine instruments.
- The canals are cleaned, shaped, and disinfected.
- The canals are filled with a rubber-like material called gutta-percha and sealed.
- The tooth gets a filling, and usually a crown later to protect it.
The outer tooth stays. You keep chewing on your own root, held in place by your own ligament and bone.
What does an extraction involve?
An extraction removes the whole tooth, root and all. A simple extraction loosens the tooth and lifts it out. A surgical extraction may need a small incision or sectioning the tooth into pieces.
Healing of the gum takes 1 to 2 weeks. The bone fills in over a few months. Then comes the question of what to do with the space.
Root canal vs extraction: side-by-side comparison
| Factor | Root canal + crown | Extraction |
|---|---|---|
| Keeps natural tooth | Yes | No |
| Number of visits | Usually 1 to 2, plus a crown | Usually 1, plus replacement later |
| Recovery | A few days of mild soreness | 1 to 2 weeks for the gum |
| Effect on jawbone | Bone stays stimulated | Bone shrinks over time without replacement |
| Effect on other teeth | Bite stays stable | Neighbours can tip and drift into the gap |
| Long-term success | Often 85% to 95% at 10 years | Depends on replacement chosen |
| Total treatment over time | Usually less when tooth is restorable | Often more once replacement is included |
When is a root canal the better choice?
- The infection or inflammation is inside the tooth, but the root is solid.
- There’s enough healthy tooth structure left above the gum to hold a crown.
- The gums and bone around the tooth are reasonably healthy.
- The tooth is important for chewing or appearance, like a molar or front tooth.
- You’d rather avoid an implant, bridge, or denture.
When is extraction the better choice?
- Vertical root fracture: a crack that runs down the root usually can’t be repaired.
- Not enough tooth left: decay has destroyed so much that a crown has nothing to grip.
- Severe gum disease: the tooth is very loose because the bone around it is gone.
- Wisdom teeth that are impacted, hard to clean, or causing repeated problems.
- Failed retreatment: the tooth has already had root canal work that didn’t heal, and further options aren’t practical.
- Orthodontic planning: sometimes a tooth is removed to create space.
What happens if you pull a tooth and don’t replace it?
This part often gets skipped in the rush to stop the pain. Over months and years, a missing tooth can lead to:
- Neighbouring teeth tipping into the gap
- The opposing tooth growing longer into the space (over-eruption)
- Food traps and gum problems around the tilted teeth
- Bone loss in the jaw where the root used to be
- Changes in your bite and more wear on the remaining teeth
- A sunken look in the face if several back teeth are lost
One missing back tooth may not feel like a big deal at first. The changes are slow, which is why they surprise people later.
How do dentists decide if a tooth can be saved?
A careful assessment usually includes:
- Symptoms and history. How long has it hurt? Any swelling? Previous treatment on that tooth?
- X-rays. These show the root shape, bone level, and any infection at the tip.
- 3D imaging when needed. A CBCT scan can reveal cracks or extra canals.
- Gum measurements. Deep pockets around just one side can hint at a crack.
- Restorability check. Is there enough sound tooth to support a crown?
- Your overall health and goals. Medical conditions, budget planning, and your preferences all matter.
A good dentist will explain the odds for your specific tooth, using your own X-rays.
Does the tooth’s position change the decision?
It does. Where the tooth sits affects how much it matters, how easy it is to treat, and what replacing it would involve.
Front teeth
Front teeth usually have a single, straight canal, so root canals here are often quick and very successful. Losing a front tooth also affects your smile and speech right away, which pushes most people toward saving it.
Premolars
These have 1 or 2 canals and handle a fair amount of chewing. They’re often good candidates for saving, but they’re also prone to vertical cracks, especially after large fillings.
First and second molars
Molars do the heavy chewing and have 3 or 4 canals, sometimes more. Treatment takes longer and needs a crown afterwards. Because they’re so important for chewing, saving them is usually worth it when the roots are healthy.
Wisdom teeth
Wisdom teeth are the exception. They’re hard to reach, hard to clean, and often not needed for chewing. Removal is usually the more sensible choice when they cause trouble.
Age and overall health also play a part. A healthy 25-year-old and an 80-year-old with several medical conditions may get different recommendations for the very same tooth, and that’s appropriate.
Is a root canal more painful than an extraction?
For most people, neither is very painful during the procedure, because the area is fully numbed. Afterwards:
- A root canal typically causes mild tenderness for a few days.
- An extraction causes soreness and swelling for several days, with a small risk of dry socket.
The pain people associate with root canals is usually the infection beforehand. Treatment is what stops it.
Common myths about saving vs pulling teeth
“Root canals make you sick.” This idea comes from century-old research that has been thoroughly discredited. Modern studies show no link between root canal treatment and diseases elsewhere in the body.
“An implant is just as good as a natural tooth, so why bother saving it?” Implants are excellent replacements. Your natural tooth, when it’s restorable, still has advantages like its natural ligament cushioning and no surgery needed.
“Antibiotics can fix a tooth infection.” Antibiotics may calm a spreading infection, but they can’t reach bacteria sealed inside a dead pulp. The source has to be treated with a root canal or extraction.
“Pulling a tooth is always cheaper.” The extraction alone costs less, but replacing the tooth properly usually adds more treatment over time.
A few real-world examples
Saved molar. A patient in their 30s had a lower molar with deep decay and lingering pain. X-rays showed a solid root and healthy bone. A root canal and crown later, the tooth is still in service years on.
Cracked premolar. Another patient had a premolar with a crack running deep under the gum on one side. It couldn’t be sealed. Extraction followed by an implant was the reliable option.
Loose front tooth. An older patient with advanced gum disease had a front tooth that moved noticeably. Saving it wasn’t realistic, so it was removed and replaced with a partial denture while the gums were treated.
What should you do right now if your tooth hurts?
- Rinse gently with warm salt water.
- Take over-the-counter pain relief as directed on the label.
- Avoid chewing on that side and skip very hot or cold food.
- Call a dentist, and say whether you have swelling or fever.
- Go to hospital if swelling affects your eye, breathing, or swallowing.
Please don’t wait it out hoping the pain goes away on its own. When a nerve dies, pain sometimes fades, but the infection doesn’t.

Frequently asked questions
How long does a root canal tooth last?
With a well-fitting crown and good oral hygiene, a root canal treated tooth can last decades and often a lifetime. Delaying the crown on a back tooth raises the risk of fracture.
Can I get an implant right after an extraction?
Sometimes. If the bone is healthy and there’s no active infection, an implant may be placed the same day. Other times the site needs a few months to heal first, or a bone graft.
Is it okay to leave a gap after pulling a back tooth?
It’s possible, but neighbouring teeth often shift and the bone shrinks over time. Talk to your dentist about the effects on your specific bite before deciding.
What if I can’t afford a crown right after my root canal?
Tell your dentist. A strong temporary restoration can protect the tooth for a short time while you plan, but the crown shouldn’t be delayed for long on a back tooth.
Does a root canal take longer than an extraction?
A root canal usually takes 60 to 90 minutes and may need 2 visits. A simple extraction is quicker, but replacing the tooth afterwards adds more appointments over time.
Conclusion
Saving a restorable tooth with a root canal is usually the better long-term option for your bite and jawbone.
Extraction is the right call when a tooth is cracked deep, badly broken down, or very loose.
An honest exam with X-rays tells you which group your tooth falls into.
