A dentist tells you the tooth is badly infected, and then gives you a choice: save it or pull it. If you are weighing root canal vs extraction, you are probably looking at two very different numbers on the estimate and wondering whether the cheaper one is actually cheaper.
It usually is not. Pulling a tooth costs less today, but the space it leaves behind rarely stays empty without consequences. Replacing that tooth later often costs several times what saving it would have.
This guide covers what each procedure involves, realistic price ranges with and without insurance, how much discomfort to expect, success rates over ten and twenty years, when extraction genuinely is the better call, and how to handle the decision when money is tight right now.
What a root canal actually does
Inside every tooth is a chamber of soft tissue called the pulp, made of nerves and blood vessels. When deep decay, a crack, or repeated dental work lets bacteria reach that chamber, the pulp becomes inflamed or infected. That is what produces the throbbing, the sensitivity to heat, and eventually the abscess.
Root canal treatment removes the infected pulp, disinfects and shapes the canals inside the roots, and seals them with a rubber-like filling material. The tooth stays in place. It no longer has a live nerve, which is why it stops hurting, but the root remains anchored in the bone and continues to do its job of chewing.
Almost every back tooth that receives a root canal also needs a crown afterward. A treated molar is more brittle and can fracture under chewing forces without full coverage. When people say a root canal “failed,” it is often because the crown was skipped or delayed.
What extraction involves
A simple extraction removes a tooth that is visible and reasonably intact, using local anesthetic and elevators to loosen it. A surgical extraction is needed when the tooth is broken at the gumline, has curved roots, or is impacted, and involves a small incision and sometimes sectioning the tooth.
Healing takes a few days for initial comfort and several weeks for the socket to fill in with bone. The main early complication is a dry socket, where the protective clot is lost and the bone underneath is exposed. It is painful but treatable, and avoiding straws, smoking, and vigorous rinsing in the first days makes it much less likely.
Root canal vs extraction: cost comparison
Costs swing widely by region, by whether a general dentist or an endodontist does the work, and by which tooth is involved. Molars have more canals and cost more than front teeth. The table below shows commonly quoted ranges before insurance — confirm with your own dentist, since prices vary by state and year.
| Procedure | Typical cost without insurance | Typical cost with dental insurance | Notes |
|---|---|---|---|
| Root canal, front tooth | $700 – $1,200 | $200 – $500 | Single canal, usually one visit |
| Root canal, premolar | $800 – $1,400 | $250 – $600 | One to two canals |
| Root canal, molar | $1,000 – $2,000 | $350 – $900 | Three or more canals |
| Crown after root canal | $1,000 – $2,500 | $400 – $1,200 | Nearly always required on back teeth |
| Simple extraction | $150 – $400 | $50 – $150 | Cheapest option up front |
| Surgical extraction | $300 – $800 | $100 – $350 | Broken or impacted teeth |
| Implant with crown (replacement) | $3,500 – $6,500 | $2,000 – $5,000 | Often needed after extraction |
| Three-unit bridge (replacement) | $2,500 – $5,000 | $1,200 – $3,000 | Requires trimming neighboring teeth |
Run the arithmetic across the whole decision, not just this month. A molar root canal plus crown might total $2,200 to $3,500. An extraction at $300 followed by an implant at $4,500 totals more, and takes longer. Extraction only wins financially if you plan to leave the gap permanently, and that carries its own costs.
What happens if you leave the gap empty?
Teeth hold each other in position. Remove one and the neighbors begin to tip into the space while the opposing tooth in the other jaw slowly drifts down or up toward the gap. This is gradual — often years — but it is not reversible without orthodontic help.
The jawbone that once supported the root also begins to resorb, since it is no longer being loaded by chewing. That bone loss is what makes implants harder and more expensive the longer you wait, sometimes requiring a graft first.
Chewing shifts to the other side, which can overload those teeth. Cleaning gets harder around tipped teeth, raising the risk of decay in spots that were previously easy to reach. None of this is an emergency, but it compounds.
A single missing back molar is the case where leaving the space is most defensible, especially the last tooth in the arch. Many people function fine without it. A missing tooth further forward is a different story.
How much does each one hurt?
Root canal recovery
The reputation of root canals comes from an era before modern anesthetics. Today, the procedure itself is usually comparable to having a deep filling placed. The pain people remember is typically the infection beforehand, not the treatment.
Expect tenderness for two to four days afterward, mostly from the ligament around the root being irritated. Over-the-counter pain relievers are generally enough, though you should follow your dentist’s specific guidance for your situation.
After an extraction
Extraction is often more sore afterward, especially surgical extractions, with swelling that peaks around day two or three. Recovery is usually a week for normal eating, longer for a surgical site.
If dental anxiety is what is driving you toward extraction, say that out loud to your dentist. Sedation options exist, and choosing a permanent tooth loss to avoid ninety minutes in a chair is a trade most people regret later.
Success rates and long-term outcomes
Root canal treatment has a strong track record. Studies commonly report success in the range of 85 to 95 percent at follow-up periods of several years, with well-restored teeth lasting decades. Outcomes are better when a crown is placed promptly and when the tooth had good bone support to begin with.
When a root canal does not hold, the usual causes are a missed canal, a vertical root fracture, a crown that leaked and let bacteria back in, or new decay at the margin. Retreatment is possible in many of those cases, and a surgical procedure called an apicoectomy can address infection at the root tip.
Extraction is definitive — the problem tooth is gone and cannot reinfect. The long-term outcome then depends entirely on what replaces it. Implants have high survival rates over ten years in healthy patients, while bridges typically need replacement somewhere in the 10 to 15 year range. If replacement is on your horizon, it is worth reading through how dental implants vs bridges compare on cost and longevity before you agree to pull anything.
When extraction is genuinely the better choice
Saving teeth is the default goal, but it is not always the right one. Extraction usually makes more sense when:
- The tooth has a vertical root fracture, which cannot be repaired
- Decay extends well below the gumline, leaving too little structure to hold a crown
- Advanced gum disease has already destroyed most of the supporting bone
- The tooth is a wisdom tooth or otherwise non-essential to your bite
- Orthodontic treatment requires space and this tooth is the logical one to remove
- Repeated root canal treatment has already failed on that tooth
Your dentist should be able to point to the specific reason on an X-ray. “It’s cheaper” is not a clinical reason, though it can be a legitimate personal one — just make sure you are choosing it with the full picture in front of you.
How dental insurance handles both procedures
Coverage percentages and annual maximums
Most dental plans classify root canals as a basic or major service, commonly covering 50 to 80 percent after the deductible. Crowns are usually major services at around 50 percent. Extractions often fall under basic services at a higher coverage percentage.
The bigger constraint is the annual maximum. Many plans cap total yearly benefits somewhere between $1,000 and $2,000, which a root canal plus crown can exhaust in a single visit. Several legitimate workarounds are worth asking about:
- Have the root canal done in December and the crown placed in January, splitting the cost across two benefit years.
- Ask the office to submit a pre-treatment estimate so you know the exact patient portion before you commit.
- Confirm whether a waiting period applies if your plan is new — major services often have one.
- Ask about in-house membership plans, which some practices offer as a flat annual fee with set discounts.
- Check whether a nearby dental school clinic treats cases at reduced fees with supervised students.
If you are buying coverage specifically to handle a known problem, run the numbers carefully. The math on dental insurance vs dental savings plans often favors the discount-plan route when you need one large procedure quickly rather than steady preventive care.
Can you wait?
Delaying treatment on an infected tooth is the one option that reliably gets worse and more expensive. Infection can spread into the surrounding bone and soft tissue, and in rare cases becomes a serious medical emergency requiring hospital care. Facial swelling, fever, or difficulty swallowing means same-day care, not a wait-and-see week.
Pain that goes away on its own is not reassurance. It sometimes means the nerve has died, which ends the sensitivity while the infection continues quietly at the root tip.
If cost is the barrier, tell the office directly. Many practices offer phased treatment — draining an abscess and starting antibiotics now, completing the root canal in a few weeks — or payment plans that keep you from having to choose extraction for financial reasons alone.
Preventing the next one
Most teeth that end up needing this decision got there through decay that started small. Interproximal cavities between teeth are the usual culprit because they are invisible until they are large. That is why the boring advice matters: flossing reaches surfaces a brush never touches, and X-rays at recall visits catch decay while it is still a filling rather than a root canal.
Grinding is the other quiet driver, especially for cracked teeth. If you wake with a sore jaw or your dentist notes flattened chewing surfaces, a night guard is far cheaper than a fractured molar. Sensitivity that lingers after cold or sweet things deserves attention early — the common causes of tooth sensitivity range from harmless recession to a cracked cusp, and the difference matters.
Simple daily habits do most of the work here. Brushing twice with fluoride toothpaste, cleaning between teeth daily, and limiting how often you sip sugary or acidic drinks are the core of how to prevent cavities in the first place.

Frequently Asked Questions
Is a root canal always better than pulling the tooth?
Not always, but it is the default when the tooth is restorable. Keeping your natural tooth preserves bone, keeps neighboring teeth from drifting, and avoids the cost of replacement. Extraction is the better choice when the root is fractured, too little tooth structure remains, or gum disease has already destroyed the supporting bone.
How long does a tooth last after a root canal?
Many treated teeth last decades, and some last a lifetime. Longevity depends heavily on getting a well-fitting crown placed promptly on back teeth, keeping the margins free of new decay, and avoiding heavy grinding forces. Teeth that fail usually do so because of a missed canal, a fracture, or leakage under an aging restoration.
Why does the crown cost more than the root canal sometimes?
The root canal treats the infection; the crown rebuilds the tooth so it can survive chewing. Crowns involve lab fabrication, materials like zirconia or porcelain, and two appointments in many offices. Skipping it to save money frequently leads to a fractured tooth that then must be extracted anyway.
Can I get an implant right after an extraction?
Sometimes. Immediate placement is possible when there is enough healthy bone and no active infection, but many cases require three to six months of healing first, and some need a bone graft. Your dentist will decide based on imaging. Plan for the full timeline and cost before choosing extraction over saving the tooth.
Does dental insurance cover both options?
Most plans cover both, though at different percentages, and both count against the same annual maximum. Extractions are often covered at a higher rate as a basic service, while crowns fall under major services. Ask for a written pre-treatment estimate so you see your actual out-of-pocket amount before scheduling.
The Bottom Line
The root canal vs extraction decision looks like a price comparison and is really a timeline comparison. Extraction wins the first invoice; saving the tooth usually wins over ten years, because a gap rarely stays a gap without bone loss, drifting teeth, and a replacement bill.
Ask your dentist to show you exactly why the tooth is or is not restorable, get a written estimate for the full treatment including the crown, and ask about splitting the work across benefit years if the annual maximum is the obstacle. If the answer is still extraction, plan the replacement at the same time rather than later. Confirm all costs and coverage with your own dentist and plan, since they vary by state, insurer, and year.
