Quick answer
A root canal is usually the first choice when a tooth can be restored, because it keeps your natural tooth. An implant makes sense when the tooth cannot be rebuilt. Studies report high survival for both, about 97 percent at 8 years for root-canal-treated teeth and 97 percent at 5 years for implants, but they are not head-to-head comparisons.
The deciding questions are not about which treatment sounds more modern. They are about how much sound tooth is left, whether there are cracks, and how healthy the bone around the tooth is. This guide gives you a framework to follow.
What is the difference between a root canal and an extraction with an implant?
A root canal cleans out the damaged nerve space inside a tooth, seals it, and keeps the tooth in place. An extraction removes the whole tooth, and an implant replaces the root with a post that holds a crown. The American Association of Endodontists (AAE) says the usual alternative to a root canal is extraction (AAE, 2026).
The AAE also calls both approaches viable and describes an implant as an excellent backup plan if the tooth cannot be saved. The same page notes that a bridge or removable partial denture often needs work on adjacent healthy teeth.
Our pages on root canal therapy, tooth extractions, and single tooth implants explain each treatment step by step.
How long do root canal teeth and implants last?
Both have high survival in large studies, in the range of 87 to 97 percent depending on the study, tooth, and time frame. The table shows what each named study measured. These numbers are not a head-to-head contest, because each study defined success its own way.
Treatment | Study | What it measured | Result |
Root canal | Salehrabi and Rotstein, 2004 (1,462,936 teeth, US dental plan) | Tooth still in the mouth | 97 percent at 8 years |
Root canal, back teeth | Patel et al., 2024 (meta-analysis of 20 studies) | Pooled survival of root-filled back teeth | 91 percent at 4 to 7 years, 87 percent at 8 to 20 years |
Implant | Jung et al., 2012 (46 studies, single-tooth implants) | Implant still in place | 97.2 percent at 5 years, 95.2 percent at 10 years (estimate) |
Implant crown | Jung et al., 2012 | The crown itself still in place | 96.3 percent at 5 years, 89.4 percent at 10 years (estimate) |
Survival means the tooth or implant is still in the mouth. It does not mean free of problems. Jung and colleagues concluded that technical, biological, and aesthetic complications with implant crowns were frequent, and their 10-year figures are model estimates with wider uncertainty. The Salehrabi data came from insurance records of private practices. A 2007 review of 143 studies in the Journal of Prosthetic Dentistry found direct comparisons between treatments extremely rare. It still concluded that long-term survival of implant crowns and root-canal-treated teeth was similar, and both were better than fixed bridges (Torabinejad et al., 2007).

How do you decide? A six-step framework
The decision rests on whether the tooth can be restored and kept healthy for years. Dentists look at six things in order. A "no" at an early step does not always end the discussion, but it shifts the odds. This framework turns those checks into plain steps.
How much healthy tooth structure remains? A tooth needs enough solid structure above the gum to hold a crown. Patel and colleagues list remaining coronal tooth structure and ferrule (a collar of tooth that the crown grips) among the factors tied to survival of root-filled back teeth, though they note the evidence is limited.
Is there a crack, and where does it end? The AAE says that if a crack passes below the gum line, the tooth cannot be saved and needs to be extracted (AAE, 2026). A split tooth cannot be saved intact.
How strong is the bone around the root? Periodontal disease and the crown-to-root ratio were also on Patel's list of prognostic factors (Patel et al., 2024). Deep bone loss can make a tooth a poor long-term bet.
Can the tooth be restored with a crown? In the Salehrabi study, 85 percent of the extracted root-canal-treated teeth had no full crown, and the authors found a significant difference between crowned and uncrowned teeth (Salehrabi and Rotstein, 2004). A finished crown appears to matter too.
What is your overall health and what are your goals? The Cleveland Clinic lists active gum disease and unmanaged diabetes as conditions that may make implants a poor choice, and says smoking or vaping can disrupt healing (Cleveland Clinic, 2026).
How much time and recovery can you take on? The comparison below covers visits and healing.
How do the two paths compare day to day?
A root canal usually means fewer visits and shorter recovery than an extraction followed by an implant. The AAE describes root canal treatment as often completed in one to two visits, while an implant typically requires multiple stages over several months. The table summarizes the AAE comparison.
Root canal and crown | Extraction and implant | |
Visits | Often one to two, then the final restoration (AAE, 2026) | Multiple stages over several months |
Recovery | Mild soreness for a few days | Longer healing while the implant bonds with bone |
Upfront cost | Generally lower, especially when preserving the natural tooth | Higher, due to surgery and multiple components |
Natural tooth | Kept, with its own bite alignment | Replaced with an artificial root and crown |
Jawbone | Tooth stays in the bone | Implant is placed into the jawbone, and may need grafting first |
Later care | Crown may need replacement, retreatment is possible (AAE, 2026) | Components may need maintenance or replacement |
Bone grafting is sometimes needed for implants, and the AAE page on extraction notes that replacing a lost tooth may involve bone grafts or sinus lifts (AAE, 2026).
Why do dentists usually prefer to save a natural tooth?
Dentists usually prefer to save a restorable tooth because no replacement fully matches a natural one. The AAE says nothing looks, feels, or functions like a natural tooth, and that no denture, bridge, or implant matches it (AAE, 2026). Extraction also changes things beyond the gap.
The AAE notes that spaces left by extracted teeth can cause other teeth to shift. Our post on dental implants after bone loss explains why bone changes matter later.
Be aware of a caveat. The AAE is an organization of endodontists, who perform root canals, so its materials lean toward saving teeth. The preference is also conditional. A tooth that is heavily cracked or has little bone may be more reliable to replace than to save, and a tooth saved against the odds can cost more time in the end.
What changes the answer?
Your answer shifts when specific findings change the odds for the tooth. Some findings favor saving it, and others favor replacing it. Use this list as a conversation guide with your dentist, not as a verdict, because only an exam and X-rays can confirm which findings apply to you.
Findings that tend to favor saving the tooth:
Enough solid tooth remains to hold a crown
Bone around the root looks healthy on X-rays
Any crack stays above the gum line
The tooth is important for your bite, such as a back molar you chew on daily
You prefer fewer visits and a shorter recovery
Findings that tend to favor extraction and replacement:
A crack that runs below the gum line, or a split tooth
Deep bone loss from gum disease around the tooth
Too little tooth left to rebuild
A tooth that has already failed a root canal and cannot be retreated
A history of repeated problems with the same tooth
Findings that call for caution with implants: active gum disease, unmanaged diabetes, or smoking, per Cleveland Clinic. These may need to be addressed first.
How we approach this at Gardens
At Gardens Implant & Cosmetic Dentistry in Palm Beach Gardens, Florida, we begin by finding the source of the problem and checking how much of the tooth is sound. We take X-rays, test the tooth, measure the gums around it, and look for cracks. Dr. Hans Almanzar, DDS reviews the findings with you.
We then explain what is realistic: saving the tooth with a root canal and a crown, or removing it and planning a replacement such as an implant. If a tooth is complicated, we say so and talk through who should treat it. You hear the likely outcomes and trade-offs before deciding.
Questions to ask before you decide
Good questions turn a rushed decision into an informed one. Use these at your appointment, here or at any office. They help you compare the two paths using facts about your own tooth, bone, and health rather than general rules or sales pressure:
How much of my tooth is left above the gum, and can it hold a crown?
Do you see a crack, and does it go below the gum line?
What do my X-rays show about the bone around this root?
If the root canal fails, what happens next?
How many visits and how much recovery time do I need for each path?
Does my health history change the plan for an implant?
When to call right away
Do not wait on a toothache that is changing quickly, because infection can spread. Call us right away, or go to an urgent care or emergency room if you cannot reach us, when you notice any of these signs of a possible infection or a worsening problem:
Swelling in your face, jaw, or gums
Fever along with tooth pain
Pus coming from the gums or tooth area
Severe pain that keeps you awake or does not ease with medication
Trouble breathing or swallowing, which is an emergency: go to the nearest emergency room or call 911 (MedlinePlus, 2025)
Frequently asked questions
Is it better to get a root canal or an implant?
When a tooth can be rebuilt and its supporting bone is healthy, a root canal followed by a crown is usually the first choice, since it keeps your natural tooth. When the tooth cannot be restored, an implant is an established replacement. The answer depends on your X-rays and exam.
How long does a tooth last after a root canal?
Often many years, but no one can promise a number. In a study of about 1.46 million treated teeth, 97 percent were still in the mouth 8 years later. Most lost teeth had no full crown. A pooled analysis of back teeth found 91 percent survival at 4 to 7 years and 87 percent at 8 to 20 years.
Can a cracked tooth be saved with a root canal?
Sometimes. The American Association of Endodontists says a crack that extends below the gum line means the tooth cannot be saved. A crack that reaches the nerve but stays above it can sometimes be treated with a root canal and a crown. Early diagnosis matters, so a cracked tooth is worth checking promptly.
Do implants last longer than root canal teeth?
Not clearly. A 2007 systematic review found long-term survival of single implant crowns and root-canal-treated teeth to be similar, and both beat traditional bridges. Studies define success differently, so direct comparison is hard. Your own bone, gums, and bite affect either result more than the label.
Which option has the shorter recovery?
A root canal usually has less downtime. The American Association of Endodontists describes mild soreness for a few days, with treatment often finished in one to two visits before the final restoration. An extraction with an implant involves surgery and bone healing over several months before the final tooth.
What if the root canal fails later?
Sometimes the tooth can be treated again, which the American Association of Endodontists calls a second chance to save it. If it cannot be saved, it can be removed and replaced. The same group calls an implant an excellent backup plan, so choosing the root canal first does not close the door.
