A root canal with the crown that must follow it typically costs $2,400 to $4,200, and you keep your own tooth and its root. An extraction costs $200 to $700 today — and then leaves you choosing between a gap, a bridge at $3,500 to $6,000, or an implant at $4,000 to $6,500.

Pulling it is cheaper today and more expensive later. That is very nearly the whole decision — but not quite, because sometimes the tooth genuinely cannot be saved, and sometimes it can be saved and still should not be.
The question behind the question
Almost nobody asks "root canal or extraction?" from a position of calm. They ask it at eleven at night, in pain, on a phone, having just been told a number they were not expecting.
So before anything else: the pain is not the decision. Both treatments end the pain. A root canal ends it by removing the dying nerve. An extraction ends it by removing the tooth the nerve is in. Whichever you choose, you will not be in pain by tomorrow.
What you are actually deciding is what your mouth looks like in ten years, and what you will have spent by then. Which means it is worth twenty minutes of clear thinking, and this article is those twenty minutes.
What each procedure actually does
A root canal. Inside every tooth is a chamber containing soft tissue — nerve, blood vessels, connective tissue. When deep decay, a crack or an injury lets bacteria reach it, that tissue becomes inflamed, then infected, then dies. It cannot heal on its own, and the infection spreads out of the root tip into the bone, where it forms an abscess.
A root canal cleans that chamber out, disinfects it, shapes the narrow canals that run down each root, and seals them. The tooth is then dead — and that is fine, because a tooth does not need a nerve to chew. It needs a root. A root canal is how you keep one.
An extraction. The tooth is loosened in its socket and lifted out. It is not so much pulled as eased. A simple extraction takes minutes; a surgical one, where the tooth has broken down or sits below the gum, takes longer and may need a small incision and a stitch.
Does a root canal hurt? The misunderstanding that costs people their teeth
NEEDS SIGN-OFF K-06 Claims about the practice — Nitrous offered; IV / general sedation NOT offered. Approve as written, or give the correction.
This deserves its own section, because a great many people choose extraction on the strength of something that is not true.
The pain everyone associates with root canals is the pain of the infection that made the root canal necessary. A dying nerve inside a rigid tooth is genuinely one of the worst pains in medicine — it is throbbing, it does not respond well to painkillers, and it keeps you awake. That is what people remember. The treatment is what stops it.
Blaming the root canal for that pain is like blaming the ambulance for the accident.
The appointment itself: the tooth is numbed thoroughly, and a competent dentist checks you are numb and waits until you say so. Then it is a long appointment during which very little happens to you. Most patients describe it as similar to having a filling — tedious rather than painful. The commonest complaint afterwards is that the jaw ached from being open, which tells you something.
Afterwards, the tooth is tender for a few days — bruised, rather than in pain — and over-the-counter painkillers handle it.
If the idea of the appointment is the obstacle rather than the sensation, that is a solvable problem: nitrous oxide sedation exists precisely for this, and you stay awake, in control, and able to drive yourself home.
The five-minute cost comparison
NEEDS SIGN-OFF C-04, C-05, C-06, C-07, C-10, C-11, C-12, C-24 Costs stated here — crown $1,300–$2,200; three-unit bridge $3,500–$6,000; root canal, front tooth $1,000–$1,400; root canal, molar $1,400–$2,000; extraction (quoted as one range) $200–$700; single implant, post+abutment+crown $4,000–$6,500; bone graft $500–$1,200; root canal + crown, total $2,400–$4,200. Approve as written, or give the correction.
Here is the arithmetic, with the numbers from this area, laid out properly. Do it once and the decision usually makes itself.
Option A — save the tooth.
- Root canal: $1,000 – $1,400 (front tooth) or $1,400 – $2,000 (molar)
- Crown afterwards: $1,300 – $2,200
- Total: roughly $2,400 to $4,200. One tooth, yours, in your own bone.
Option B — extract and replace with an implant.
- Extraction: $200 – $700
- Bone graft to preserve the socket (usually advisable): $500 – $1,200
- Implant, abutment and crown: $4,000 – $6,500
- Total: roughly $4,700 to $8,400, over six to nine months.
Option C — extract and bridge.
- Extraction: $200 – $700
- Three-unit bridge: $3,500 – $6,000
- Total: roughly $3,700 to $6,700 — and two healthy teeth either side are ground down to carry it.
Option D — extract and leave the gap.
- Total: $200 to $700 today. And then read the next section but one.
Insurance changes the shape of this but rarely the direction of it: most plans contribute meaningfully toward root canals and crowns, because they are restorative. Many plans cover implants poorly or not at all. Which tilts the arithmetic further toward saving the tooth, not away from it.
When the tooth genuinely cannot be saved
Sometimes there is no decision to make, and an honest dentist will tell you so rather than take your money for a treatment that is going to fail.
A vertical root fracture. A crack running down the length of the root, below the bone. The tooth cannot be sealed, the infection cannot be excluded, and it will fail. This is the commonest genuine reason to extract.
Too little tooth left to hold a crown. A crown needs something to grip — a collar of solid tooth structure, at least a couple of millimetres of it, above the bone. If decay has eaten the tooth down below that line, there is nothing to build on. Crown-lengthening surgery can sometimes create it; often it is not worth it.
Severe bone loss from [gum disease](/gum-disease-treatment-bridgeport). The root canal would succeed and the tooth would still be loose, because the bone holding it in has gone. Treating the nerve of a tooth that is going to fall out anyway is money wasted.
Decay that has reached deep below the gum, where the margin of any restoration could never be sealed or cleaned.
When extraction is right even though the tooth could be saved
This is the section that most articles leave out, and it matters.
When the tooth is not doing anything. A wisdom tooth. Sometimes a second molar right at the back, where the tooth in front is doing the work and nothing sits above it. Spending $3,500 saving a tooth you would not miss is not good judgement.
When the whole quadrant needs a plan. If three teeth in a row are failing, a coherent plan for the whole area sometimes means sacrificing one that could have been individually rescued.
When it is a retreatment of a retreatment. A tooth that has already had a root canal, then a retreatment, then an apicoectomy, and is still symptomatic, is telling you something. There is a point at which continuing is throwing money after money.
When you honestly cannot afford it, and delay would make things worse. This is a real clinical consideration, not a failure of nerve. A tooth left in pain and untreated for six months while you save up is a tooth that may abscess, and an infection that spreads into the face is a hospital problem. An extraction you can afford today is better than a root canal you cannot afford until March. Any dentist who cannot have that conversation with you plainly is not the right dentist.
What happens to the gap if you do nothing
Extraction is often presented as the end of the story. It is the beginning of one.
The tooth above drifts down. With nothing to bite against, the opposing tooth erupts further out of its socket — over years, sometimes centimetres. It ends up hanging into the gap, and eventually it becomes unstable and is lost too.
The teeth either side tilt in. They lean into the empty space. Your bite changes. Food packs into the new angles, and decay follows.
The bone thins. The bone of your jaw is maintained by the forces of chewing, transmitted through the root. Take the root away and it resorbs, fastest in the first year. This is why the longer you wait to place an implant, the more likely you are to need a bone graft to do it.
And the chewing moves to the other side, which over years overloads it.
None of this happens next week. All of it happens. The gap is cheapest to close on the day the tooth comes out, and it gets more expensive every year that follows.
For a lower back molar that nobody sees and that has no opposing tooth to drift, leaving the gap is a defensible choice, and I will say so. For anything else, it is a decision to pay later rather than now.
Success rates, honestly
Root canals succeed in the region of 85–95% of cases in competent hands, and a successfully treated tooth can last decades — frequently for life. The variables that matter most are how badly infected it was at the start, whether the canals could all be found and cleaned, and — critically — whether a proper crown went on afterwards and how quickly.
Failures happen. A canal missed, a crack found later, a re-infection through a leaking restoration. Retreatment is possible and often successful. Occasionally the tooth is lost anyway, two years later, and you will have spent the money for nothing. That is the risk you are accepting, and you should accept it knowingly. It is a good bet, not a certainty.
Implants succeed at broadly similar rates — around 95% over ten years — which is why nobody should tell you an implant is a lesser option. It is not. It is a more expensive one, and it costs you a tooth you already own.
The crown afterwards is not optional
If you take one practical thing from this article, take this.
On a back tooth, a root-treated tooth without a crown will very often split, and when it splits it is usually unsaveable. The tooth has been hollowed out. It has lost the internal structure that made it strong, it no longer feels pain to warn you, and it takes the heaviest chewing force in your mouth.
The commonest way people lose a root-treated molar is this: the root canal is done, the pain stops, the crown is postponed because money is tight, six months pass, and the tooth cracks in half on a piece of bread. Now the root canal you paid $1,600 for is wasted, and you are having the extraction you were trying to avoid, and paying for that too.
So budget for the crown from the start. It is part of the treatment, not an addition to it. A quote for a root canal that does not mention the crown is not a real quote. On a front tooth with little damage, a filling is sometimes genuinely enough — and a good dentist will tell you when that is the case.
"Root canals make you sick" — the claim, and the evidence
You will encounter this online, and you deserve a straight answer rather than a dismissal.
The claim descends from focal infection theory, an idea from the early twentieth century — associated with a dentist named Weston Price — holding that root-treated teeth harbour bacteria that seed disease throughout the body. It was influential enough that healthy teeth were extracted in large numbers on the strength of it.
The research it rested on does not meet any modern standard of evidence. It lacked controls, it was not reproducible, and the theory was substantially abandoned by mainstream medicine by the mid-twentieth century. The American Dental Association, the American Association of Endodontists and the major systematic reviews find no credible evidence that root canal treatment causes systemic illness.
What is true, and worth saying: an infected tooth left untreated is a genuine chronic infection in your body, and there is reasonable evidence linking chronic oral infection to worse outcomes elsewhere. The treatment that removes that infection is the root canal. The theory, in other words, has it exactly backwards.
If someone is offering to extract healthy or treatable teeth on the strength of focal infection theory, get a second opinion from someone who is not.
What actually happens during a root canal, step by step
Fear thrives on not knowing. Here is the entire appointment, in order.
Numbing. Topical gel first, so you do not feel the injection going in. Then the local anaesthetic, given slowly — given slowly it stings far less. Then several minutes of waiting, which is not the dentist being unhurried but the anaesthetic doing its work. Then a check: are you numb? Nothing begins until you have said yes out loud.
If a tooth is badly infected, numbing it can be harder — infection changes the local chemistry — and additional techniques may be needed. Say so if you feel anything. There is more available; you do not have to be brave.
The rubber dam. A small sheet of latex is stretched over the tooth. Patients dislike the sound of this and then, almost universally, prefer it: it keeps water and debris out of your throat, it stops you tasting anything, and it means you do not need to swallow around instruments. It also keeps the tooth clean and dry, which is a large part of why the treatment works.
The access. A small opening is made through the top of the tooth into the chamber. You feel nothing — the tooth is numb, and in many cases the nerve inside is already dead.
Cleaning the canals. The infected tissue is removed and each canal is cleaned, shaped and disinfected with fine instruments and irrigating solutions. A front tooth typically has one canal; a molar has three or four, and sometimes a fourth that is genuinely difficult to find. This is the long part. It is also the part that determines whether the treatment succeeds, which is why it should not be rushed.
Sealing. The canals are filled with a rubber-like material and sealed so bacteria cannot re-enter.
The temporary filling — and then the crown, at a subsequent appointment.
What you will actually experience: a long time with your mouth open, the sound of small instruments, occasional water, and a jaw that aches from being open. A bite block helps and you are entitled to ask for one, and for breaks.
Antibiotics are not a treatment
This matters, and it is a common and expensive misunderstanding.
You may have been given antibiotics for a dental infection, and they may have made the pain go away. They did not fix it.
An infected tooth is a chamber with no blood supply — the nerve is dead, which is exactly why it is infected. Antibiotics travel in the blood. They cannot reach the inside of the tooth, because nothing reaches the inside of the tooth. What they can do is knock back the infection in the surrounding bone, which reduces swelling and pain, buys time, and makes people believe the problem is solved.
It is not solved. The source is still in the tooth, and it will flare again — often in weeks, sometimes in months, and usually at an inconvenient time. Each cycle of "antibiotics, feel better, stop taking them, flare again" does further damage to the bone and makes the tooth harder to save.
Antibiotics have a legitimate role: where infection is spreading into the face, where there is systemic involvement, or to make a tooth safely treatable. They buy time. They are not the treatment, and a dentist who prescribes them repeatedly without addressing the tooth is not treating you.
Will the tooth go dark?
NEEDS SIGN-OFF K-17 Claims about the practice — Internal bleaching offered. Approve as written, or give the correction.
Sometimes, and it is fixable, so it should not be the thing that tips your decision.
A root-treated front tooth can darken over the following years — a grey or yellow cast, because the tooth is no longer alive and the internal tissue that discoloured it was not perfectly cleaned out. It is more common in teeth treated a long time ago.
Internal bleaching — whitening gel placed inside the tooth rather than on it — usually corrects this, at a cost far below a veneer or a crown. Ask about it before you accept porcelain as the only answer.
On a back tooth, it does not matter and nobody will see it.
Retreatment, apicoectomy, and what happens if it fails
Root canals succeed most of the time. They do not always, and you deserve to know what happens next rather than discovering it.
Retreatment. The old filling material is removed, the canals are re-cleaned — often finding the canal that was missed the first time — and re-sealed. Success rates are lower than for a first attempt but still good. It costs roughly what the original treatment cost, sometimes more.
Apicoectomy. A small surgical procedure: the very tip of the root, where the infection persists, is removed through the gum and sealed from the end. It is done when retreatment is not possible or has not worked. It sounds far worse than it is; most patients report it as comparable to an extraction.
And then extraction. If a tooth has had a root canal, a retreatment and an apicoectomy and is still symptomatic, it is telling you something. There is a point at which continuing is throwing money after money, and a good dentist will say so.
What you should ask before the first root canal: what happens if it does not work, what would come next, and what that would cost. A treatment that has a plan for its own failure is a treatment you can commit to with your eyes open.
How to decide, in four questions
NEEDS SIGN-OFF K-02 Claims about the practice — Root canal treatment performed in-house. Approve as written, or give the correction.
- Can it actually be saved? Ask directly. Ask what specifically would make it unsaveable, and whether your tooth has that. Ask to see the X-ray.
- What will I do about the gap if I pull it — honestly, and with a number? If the answer is "nothing", make sure you are choosing that rather than defaulting to it.
- Is the crown in the quote? If not, the quote is wrong.
- Can I afford the whole plan, not just the first appointment? If not, say so out loud in the office. It changes the advice, and it should.
