Root Canal vs. Extraction: What Each Costs, and Why the Cheaper One Isn't Always Cheaper

What does a root canal actually cost?

A root canal alone typically costs $700-$1,800 per tooth, depending on which tooth it is — molars have more canals and take longer than front teeth, so they cost more. Add the crown almost every root-canaled back tooth needs, and the combined cost is usually $1,500-$3,500. A root canal removes the inflamed or infected pulp inside the tooth, cleans and shapes the canals, then fills and seals them to relieve pain and keep the natural tooth in place 1Ref 1American Association of Endodontists (2024).Root Canal Treatment.What a root canal does: removes inflamed/infected pulp, cleans and shapes the canals, fills and seals the tooth to relieve pain and save the natural tooth.. Endodontists (root canal specialists) generally charge more than general dentists for the same procedure, particularly on molars, but they also see more of these cases. Getting a written, itemized estimate before treatment — root canal, any core buildup, and the crown listed as separate line items — is the only way to compare it honestly against extraction.

What does an extraction actually cost?

A simple extraction of a visible, erupted tooth is usually $150-$450. A surgical extraction — needed when the tooth is broken at the gumline, impacted, or the roots are curved or fused to bone — runs $250-$700 or more, and can climb higher with sedation. The extraction quote by itself is almost never the full comparison, because it doesn't include what happens to the gap it leaves. A tooth that isn't replaced can let neighboring teeth drift, change the bite, and eventually cost more to fix than either original option would have. A tooth that is replaced — with an implant or a bridge — usually costs more in total than the root canal that would have kept the original tooth.

The real comparison: root canal vs. extraction plus replacement

Comparing the two options fairly means pricing what each one actually leaves behind, not just the procedure itself.

Professional guidance from endodontists generally favors keeping the natural tooth when the tooth can be saved, in part because a root-canaled tooth that's restored with a crown tends to function like the rest of the natural dentition, while a bridge requires grinding down two healthy neighboring teeth to serve as anchors 2Ref 2American Association of Endodontists (2024).Root Canal vs Extraction.The trade-off between saving a tooth with root canal versus extraction plus a bridge or implant, and that the AAE favors keeping the natural tooth when feasible.. That's a clinical and cost-avoidance argument, not a claim that extraction is ever the wrong choice — some teeth are too broken down, too infected, or too compromised by gum disease to be worth saving, and a dentist or endodontist evaluating the actual tooth is the only source for that judgment.

Why dentists often recommend keeping the natural tooth when it's feasible

Endodontic organizations describe preserving the natural tooth as generally preferable to extraction and replacement when the tooth can be restored, because the body's own tooth and root typically function, feel, and last differently than an artificial replacement 3Ref 3American Association of Endodontists (2024).Saving Your Natural Tooth.General rationale for preserving the natural tooth through endodontic treatment versus replacement options.. That preference is about long-term function, not a rule that applies to every tooth: a tooth with a vertical root fracture, extensive bone loss around the root, or a canal system that can't be adequately cleaned may not be a good root canal candidate regardless of cost. If a dentist recommends extraction over a root canal, that's usually because the tooth's specific condition makes saving it unlikely to succeed — not because extraction is being chosen to save money.

What makes a tooth an extraction candidate instead

A few situations push toward extraction regardless of cost. A tooth broken below the gumline with too little structure left to support a crown is one. Severe gum disease that has already destroyed the bone supporting the tooth is another — a root canal doesn't fix a loose tooth. An untreated infection can also progress to a dental abscess, a pocket of infection at the root tip caused by decay, gum disease, or a cracked tooth that lets bacteria reach the pulp 4Ref 4American Dental Association (2024).Abscess.Definition and causes of a dental abscess: infection from tooth decay, periodontal disease, or a cracked tooth allowing bacteria into the pulp.; a badly abscessed tooth with extensive bone loss may no longer be salvageable even with a root canal. In any of these cases, the honest cost comparison isn't root canal versus extraction — it's extraction versus extraction, because the root canal option was never really on the table for that tooth.

If the tooth is extracted, why replacing it changes the total

An empty space left by an extraction doesn't stay stable on its own. Neighboring teeth can tip into the gap and opposing teeth can over-erupt into it over months to years, which is why many people who skip replacement end up paying for orthodontic or restorative work later that a root canal would have avoided. If replacement is planned, a dental implant works by placing a titanium post that fuses to the jawbone through a process called osseointegration, then topping it with an abutment and a crown 5Ref 5American Association of Oral and Maxillofacial Surgeons (2024).Dental Implant Surgery.The three parts of an implant restoration: a titanium implant that fuses to the jawbone, an abutment, and a crown.; that fusion process typically takes several months before the crown can be attached 6Ref 6American Association of Oral and Maxillofacial Surgeons (2024).How Do Dental Implants Work?.That osseointegration (the implant fusing with the jawbone) typically takes several months before the crown can be placed.. A bridge instead anchors a replacement tooth to crowns on the two neighboring teeth, which means grinding down teeth that may otherwise be healthy. Either replacement path is a second, separate cost on top of the extraction itself, and it's the piece that most often makes extraction the more expensive road in total.

Questions worth asking before deciding

A few questions to a dentist or endodontist tend to surface the real cost difference fast: what is the prognosis for this specific tooth if it gets a root canal — is it a good candidate or a marginal one? If the tooth is extracted, is replacement medically advisable given its position (a back molar that isn't visible and doesn't affect the bite may not need replacing at all)? What does the written treatment plan show as the itemized total for each path, including the crown or bridge or implant restoration, not just the procedure being quoted first? A pre-treatment estimate that separates every line item makes it possible to compare the two paths on the same terms instead of comparing one number against a different, incomplete one.
