A failing tooth presents a fork in the road: save it with root canal therapy (and usually a crown), or extract and replace with a dental implant. Neither is universally correct. The right answer depends on the tooth, the patient, and an honest assessment of long-term prognosis.

When Root Canal Is the Right Choice

The tooth has sound structure below the gum line
There is sufficient remaining tooth to support a crown
The root is intact and not vertically fractured
Periodontal health is good
The patient prefers to keep the natural tooth

A well-executed root canal followed by a proper crown has 10-year survival in the 85–95% range. Saved teeth keep their original proprioception (the sensory input from the ligament around a natural tooth) that no implant can replicate.

When Implant Is the Right Choice

The tooth has a vertical root fracture (the single most common reason to extract rather than treat endodontically)
The tooth has been root-canal-treated multiple times and is failing again
Not enough sound tooth structure remains to support a crown
Severe bone loss from long-standing periodontal disease
Severe caries extending well below the gum line
The cost-benefit of heroic tooth-saving treatment is unfavorable

The “Save Every Tooth” Myth

Some clinicians reflexively favor root canal therapy for every salvageable tooth. Sometimes this is right; sometimes it condemns the patient to years of escalating treatment on a tooth that will be lost eventually — often with less bone remaining for a future implant than was available at the original decision point.

The “Just Pull It” Problem

The opposite error is extracting teeth reflexively. Implants are excellent but not superior to healthy natural teeth. When a tooth can be saved reliably, saving it usually makes sense.

Second Opinions Are Worth It

A prosthodontist’s perspective on a save-or-replace decision is often different from that of a general dentist or endodontist. We see both outcomes downstream — saved teeth that failed years later, and implants that are performing beautifully a decade in. That downstream view informs how we advise at the decision point.
