Should I Save the Tooth or Replace It With an Implant? A Washington, DC Decision Guide

Practice clinician: Gerald M. Marlin, DMD, MSD, prosthodontist, Elite Prosthetic Dentistry, Friendship Heights, Washington, DC. Last updated October 30, 2026.

A cracked tooth, a tooth with decay under an old crown, or a root canal treated tooth that has become sore again raises the same question: is it worth saving, or should it come out and be replaced with an implant? Both answers are sometimes right. The mistake is to treat either one as automatic. This guide explains what makes a tooth worth keeping, what makes it hopeless, why an implant is a replacement rather than an upgrade, and what to ask before anything irreversible is done.

Patients bring this question to Elite Prosthetic Dentistry from several directions. A general dentist has found decay under a crown and recommended extraction and an implant. An endodontist has said the root canal failed. A tooth has fractured and the patient has been told it cannot be rebuilt. Or the patient has read that implants are more predictable and wonders whether to skip the repair altogether. Each case is decided the same way: by the condition of that tooth, not by a general preference for teeth or for implants.

A Tooth Is Worth Saving When These Things Are True

• The root is intact. No vertical fracture, and no resorption that has hollowed the root from inside or outside.
• Enough tooth remains above the bone to hold a crown. A crown needs sound tooth structure to grip; crown lengthening can expose more when the margin sits too close to the bone, but there is a limit.
• The bone around the root is adequate. A tooth with moderate bone loss that is stable and cleanable can be kept; a tooth that moves because its support is gone cannot.
• Any infection can be resolved. Root canal treatment, retreatment, or surgery at the root tip can resolve most infections when the root is sound and the canal can be reached.
• The restoration can be designed to protect it. A tooth that has lost structure needs a crown designed for the forces it will carry, and a bite that does not overload it.

When these conditions hold, saving the tooth preserves the ligament, bone and sensation that an implant does not replace. The patient keeps a natural tooth, and the implant option remains available later if it is ever needed.

A Tooth Is Hopeless When These Things Are True

• A vertical root fracture. Once a root is split along its length, bacteria track into the fracture and the tooth cannot be sealed. It should be removed.
• Decay or resorption below the bone. When the damage extends where a restoration cannot reach and crown lengthening cannot expose it, the tooth cannot be restored predictably.
• Too little tooth left. A root with almost nothing above the bone, even after crown lengthening, cannot support a crown that will last.
• Advanced bone loss. When periodontal disease has removed most of the support and the tooth is mobile, keeping it risks the neighboring bone.
• An infection that cannot be resolved. A root canal that has failed retreatment, a canal that cannot be reached, or a persistent infection after surgery.

These findings should be visible on the examination, the X-rays or the CBCT scan, and the clinician should be able to show them to you. A recommendation to extract that rests on a general statement (“it is a weak tooth,” “implants are more predictable”) rather than a specific finding deserves a second look before the tooth is gone.

Why an Implant Is a Replacement, Not an Upgrade

Implants are an excellent solution for a missing tooth. They are not a better version of a natural tooth. An implant has no ligament, so it does not provide the sensory feedback or shock absorption of a tooth. It is attached directly to bone and is more vulnerable to overload in a heavy bite. The gum around it is less resistant to inflammation than the gum around a tooth. And an implant can fail, develop bone loss or need its crown replaced, just as a tooth can.

None of this argues against implants. It argues against removing a savable tooth on the assumption that the implant will be trouble-free. The right comparison is the prognosis of this tooth, saved, against the prognosis of an implant in this site, in this bone, in this bite. Sometimes the implant wins that comparison clearly. Sometimes the tooth does.

What the Evaluation Should Give You

• The specific finding for the tooth, with the imaging that shows it.
• Whether retreatment, crown lengthening, a new post and core, or a redesigned crown was considered, and why each was kept or ruled out.
• A prognosis for the tooth if it is saved: good, guarded or poor, and the reason.
• If replacement is recommended: whether the bone will support an implant in the correct position, whether grafting would be needed, whether a bridge is a reasonable alternative, and what the plan is if an implant does not integrate.
• How the bite affects either choice, since a tooth or an implant placed into an overloaded bite will fail either way.

A patient who leaves with those answers can make the decision. A patient who leaves with a quote for an implant and no finding for the tooth cannot.

How Elite Prosthetic Dentistry Approaches the Decision

The practice provides both answers, which is why its advice is not shaped by what it is able to do. Dr. Gerald M. Marlin evaluates the tooth on examination and imaging, including a CBCT scan where the finding depends on it, and classifies it as savable with a stated prognosis or hopeless with a stated reason. Where the tooth can be kept, the practice coordinates endodontic treatment or retreatment with specialist colleagues where needed, arranges crown lengthening where the margin requires it, and designs the post, core and crown in its on-site laboratory. Where the tooth cannot be kept, Dr. Marlin plans, surgically places and restores the implant in the same office, with the final crown designed before the surgery so the implant is placed where the tooth needs it.

Dr. Marlin has placed more than 3,900 dental implants and holds 9 U.S. patents in dental implant restoration methodology. He is also a prosthodontist whose specialty is restoring teeth, and the documented cases below include several in which the recommended extraction did not happen.

When Another Setting Fits Better

A tooth whose only problem is a failed root canal, with sound structure and no restorative complication, is well served by an endodontist for retreatment, with the crown made by the patient’s own dentist. A tooth with a clear, uncontroversial reason for extraction in a patient with a trusted general dentist and surgical colleague does not need a specialty evaluation. Active periodontal disease across the mouth should be treated before any single-tooth decision is made. The evaluation will say which applies.

Documented Cases That Show the Decision

Teeth that were saved:

• Two upper front teeth saved after another dentist and surgeon recommended extraction and implants: custom posts and crowns on intact roots.
• A root canal treated tooth with decay and resorption, recommended for an implant, resolved without the implant: the evaluation found a bite and restoration problem rather than a single failing tooth.
• Recurrent decay beneath mismatched crowns treated with root canals and buildups before a customized bridge.
• Loose, failing crowns and hidden decay: one hopeless tooth removed, strategic teeth preserved and both arches rebuilt.

Teeth that could not be saved, and what replaced them:

• A front tooth broken at the gum line in a bike accident, replaced with a graft, a guided implant and a custom crown.
• A front tooth lost to childhood trauma, rebuilt with bone grafting and a single implant.
• Failing lateral incisor implants replaced with custom zirconia bridges, a reminder that an implant is not the only replacement and not always possible.

More cases are organized in the second opinion and implant reconstruction success story hubs.

Request an Evaluation of the Tooth

If you have been told a tooth should come out, request an appointment or call (202) 244-2101 before it is extracted. Bring the X-rays and the written recommendation; the evaluation will give you a finding for the tooth and a prognosis for both choices.
