In most cases, saving a natural tooth with a root canal is the preferred option — it preserves your bite, prevents bone loss, and is usually more cost-effective than extraction plus replacement. Extraction may be the better choice when a tooth is too damaged to restore, has a vertical root fracture, or when the long-term prognosis of a root canal is poor.
What Is a Root Canal?
A root canal (endodontic treatment) is a procedure that saves a tooth by removing infected or inflamed pulp tissue from inside the tooth. The dentist cleans and shapes the internal canals, fills them with a biocompatible material, and then seals the tooth. In most cases, a dental crown is placed afterwards to protect the treated tooth and restore its full function.
The goal is straightforward: eliminate the infection while keeping your natural tooth intact. A root canal-treated tooth continues to function like any other tooth — you can chew, bite, and smile normally.
What Is a Tooth Extraction?
A tooth extraction is the complete removal of a tooth from its socket in the jawbone. There are two types:
- Simple extraction — the tooth is visible above the gumline and can be removed with standard instruments. This is a quicker procedure with a shorter recovery.
- Surgical extraction — the tooth is broken, impacted, or not fully erupted, requiring a small incision in the gum and sometimes removal of surrounding bone. Recovery takes longer, typically one to two weeks.
After extraction (unless it is a wisdom tooth), you will usually need a replacement — such as a dental implant or bridge — to prevent the problems that come with a missing tooth.
Root Canal vs Extraction: Side-by-Side Comparison
| Factor | Root Canal | Extraction |
|---|---|---|
| Goal | Save the natural tooth | Remove the tooth entirely |
| Procedure time | 1–2 visits, 60–90 min each | Usually 1 visit, 30–60 min |
| Recovery | Mild soreness for a few days | 1–2 weeks healing; longer for surgical |
| Cost at Trust Dental | From $650 + crown ($600–$1,500) | From $150 (simple) / $350–$1,250 (surgical) |
| Replacement needed? | No — tooth is preserved | Yes, unless it is a wisdom tooth |
| Replacement cost | N/A | Implant $2,449–$3,449 / Bridge $1,800–$4,500 |
| Bone preservation | Yes — root stays in the jaw | No — bone resorbs over time without replacement |
| Long-term success | 90–95% success rate over 10+ years | Permanent removal; replacement longevity varies |

When a Root Canal Is the Better Choice
A root canal is generally the preferred option when:
- The tooth can be restored — there is enough healthy tooth structure remaining to support a crown after treatment.
- The root is intact — the roots are structurally sound with no vertical fractures.
- You want to keep your natural tooth — nothing functions quite like your own tooth. A natural tooth preserves bone, maintains your bite, and avoids the need for prosthetic replacements.
- The tooth is strategically important — losing a front tooth or a key molar affects both appearance and chewing function significantly.
- You want to avoid additional procedures — extraction often leads to a chain of follow-up treatments (implant surgery, bone grafting, or bridge preparation on adjacent teeth).

When Extraction Makes More Sense
There are situations where saving a tooth is not practical or advisable:
- Vertical root fracture — a crack running down the length of the root cannot be repaired. The tooth will continue to cause pain and infection if left in place.
- Severe structural damage — if the tooth is so broken down that it cannot support a crown, even a successful root canal will not save it long-term.
- Wisdom tooth — wisdom teeth are almost always extracted rather than root canal treated (more on this below).
- Failed previous root canal with poor prognosis — if a tooth has already had root canal treatment and the retreatment prognosis is poor, extraction may be the more predictable path forward.
- Advanced periodontal disease — significant bone loss around the tooth means it may not have enough support to remain functional, regardless of whether the nerve is treated.
The Hidden Cost of Extraction
Extraction may seem like the simpler and cheaper option at first glance. But removing a tooth sets off a chain of consequences that many patients do not anticipate:
- Bone loss — once a tooth root is removed, the jawbone in that area begins to resorb. Over months and years, this can change the shape of your jaw and make future implant placement more difficult (or require bone grafting).
- Teeth shifting — neighbouring teeth gradually drift into the gap, leading to bite misalignment, uneven wear, and potential jaw joint problems.
- Need for replacement — a dental implant ($2,449–$3,449) or bridge ($1,800–$4,500) is usually needed to restore function and prevent these complications. The total cost often exceeds what root canal treatment would have cost.
- Difficulty chewing — a missing tooth affects your ability to chew properly, which can impact nutrition and quality of life.
What About Wisdom Teeth?
Wisdom teeth are a notable exception to the “save the tooth” principle. Because they sit at the very back of the mouth, are difficult to clean, and are not essential for chewing, wisdom tooth extraction is almost always the recommended approach when a wisdom tooth becomes infected, impacted, or problematic.
Root canal treatment on wisdom teeth is rarely performed because the anatomy of these teeth is highly variable, access is poor, and the long-term benefit does not justify the complexity. Wisdom teeth also do not need to be replaced after extraction.
Cost Comparison: The Full Picture
When comparing costs, it is important to look beyond the initial procedure and consider the total long-term investment:
| Scenario | Estimated total cost |
|---|---|
| Root canal + crown | $1,250–$2,700 |
| Extraction + Osstem implant | $2,449–$2,949+ |
| Extraction + Straumann implant | $3,449–$3,949+ |
| Extraction + bridge (3-unit) | $1,800–$4,500 |
| Extraction + no replacement | $150–$1,250 upfront, but risk of complications |
