A dentist tells you a back tooth is infected. In the same breath you hear two options: a root canal followed by a crown, or pulling the tooth and replacing it with an implant. Both can end with a working tooth in that spot. They get there by opposite routes. One keeps your natural root and treats it from the inside. The other removes the tooth entirely and builds a substitute anchored in the jawbone.
People are often surprised to find this framed as a choice at all. This guide explains when it genuinely is one, when it is not, and how the time, cost and travel picture differs between the two paths.
What problem are both options solving?
Inside every tooth is the pulp, soft tissue that contains nerves and blood vessels. The American Dental Association explains that pulp can become inflamed or infected after a deep cavity, repeated dental work on the same tooth, a crack, or an injury. Left untreated, infection can spread to tissue around the root, causing pain, swelling and abscesses, and can damage the jawbone and eventually cost you the tooth (ADA MouthHealthy, 2026).
Doing nothing is therefore not a neutral option once the pulp is infected. The real decision is between treating the infection inside a tooth you keep, or removing the source of infection by taking the tooth out.
Path one: root canal treatment, then a restoration
In a root canal, the dentist or endodontist numbs the area, isolates the tooth with a rubber sheet, makes an opening, removes the nerve tissue from the chamber and canals, cleans and may medicate the canals, and seals them with a rubber-like filling material. A temporary filling closes the tooth until the permanent restoration is placed. The ADA notes treatment usually takes one or two office visits, plus a follow-up for that final filling or crown, and that local anesthesia means little to no pain during the procedure (ADA MouthHealthy, 2026).
The restoration step is not optional decoration. A treated tooth has had material removed from inside it, and the final filling or crown is what protects it from breaking and from bacteria getting back in. Some teeth need a crown; others can be restored with a filling. Your dentist decides based on how much healthy structure remains.
Recovery
The ADA describes a few days of sensitivity that can usually be managed with your dentist's advice, and notes antibiotics may be prescribed if infection has spread. The American Association of Endodontists characterizes the downtime as minimal, with mild soreness for a few days (AAE, 2026).
Path two: extraction, healing, then an implant
Removing the tooth gets rid of the infected structure in one appointment. Replacing it with an implant is a longer project. A titanium or similar post is placed in the jawbone, the bone is given time to bond to it, and then an abutment and crown are attached. The AAE describes implants as typically involving multiple stages over several months, including healing time, with a longer recovery while the implant integrates with bone (AAE, 2026).
Depending on the site, the dentist may place the implant at the same time as the extraction or wait for the socket to heal first. Some patients need bone grafting before an implant can be placed. Which sequence applies to you depends on infection, bone volume and location in the mouth.
What if you just extract and stop there?
Extraction without replacement is sometimes chosen for cost reasons, especially for teeth at the very back of the mouth. Ask your dentist what a gap would mean for you specifically. The AAE notes that removing and replacing a tooth can affect the neighboring teeth and supporting gums, and that keeping a natural tooth helps preserve the jawbone around it.
Comparison at a glance
| Factor | Root canal + restoration | Extraction + implant |
|---|---|---|
| What happens to your tooth | Natural root kept and treated from inside | Tooth removed and replaced with an artificial root and crown |
| Visits | Often 1–2 visits, then the final restoration (ADA, AAE) | Multiple stages over several months (AAE) |
| Surgery | No surgery in the usual case | Extraction plus implant surgery; sometimes bone grafting |
| Recovery described by sources | A few days of soreness or sensitivity | Longer healing while the implant bonds to bone |
| Upfront cost (relative) | Generally lower (AAE) | Generally higher because of surgery and multiple components (AAE) |
| Longevity language from sources | Can last a lifetime with proper restoration and care (ADA, AAE) | Long-lasting, though components may need maintenance or replacement (AAE) |
| Main thing that can go wrong | Persistent or recurrent infection, or the tooth fracturing later | Implant failing to integrate, infection around the implant, or component problems |
None of the sources consulted for this article give a reliable head-to-head success percentage you could apply to your own tooth, and outcome claims you see in marketing deserve skepticism. The prognosis for your specific tooth is the number that matters, and only an examination with X-rays can estimate it.
When the choice is real, and when it is not
Situations that usually favor saving the tooth
- The tooth has enough healthy structure left to support a crown or filling.
- The gum and bone around it are healthy.
- There is no crack running down into the root.
- You would prefer to avoid surgery or a months-long treatment timeline.
Situations that usually favor extraction
The AAE lists reasons a tooth may not be saveable: severe damage, extensive decay, fractures below the gumline, or insufficient bone support. In those cases, a root canal may not be possible, or may simply delay an inevitable extraction while adding cost.
The gray zone
Between those poles are teeth with a guarded prognosis: a tooth that has already had a root canal and is now reinfected, a molar with complicated canal anatomy, or a tooth with moderate bone loss. Here options can include retreating the canals, a minor surgical procedure at the root tip, or extraction. This is where a consultation with an endodontist, a dentist who specializes in root canal treatment, is especially useful before you agree to remove a tooth.
Thinking about cost over time
The AAE frames the upfront cost of a root canal as generally lower than an implant. That is a useful starting point, but not the whole picture. To compare honestly, ask for itemized quotes that include:
- For the root canal path: the root canal itself, any post and core buildup, and the crown or filling. Quotes that list only the canal treatment leave out a large part of the total.
- For the implant path: extraction, any bone graft, the implant, the abutment, the crown, and the temporary tooth you wear while healing, if you need one in a visible area.
- Retreatment or replacement: ask each provider what happens, and what it costs, if the treatment does not work.

Travel implications
The two paths fit a trip very differently, and this is one of the most practical differences for anyone considering dental care in Colombia or elsewhere.
Root canal while abroad
Because treatment often finishes in one or two visits, a root canal and even a crown can sometimes fit within a single trip, depending on whether the clinic makes crowns in-house or sends them to a lab. Ask how many days you need between the canal treatment and the crown fitting. If you fly home with only a temporary filling, ask how long it is designed to last and arrange the permanent restoration promptly. Leaving a temporary in place too long can let bacteria back in.
Extraction and implant while abroad
Because implants involve healing time between stages, an implant usually means at least two trips or a long stay. Ask the clinic to lay out the full sequence: what happens on trip one, how long you wait, what happens on trip two, and what you wear in the meantime. Clarify who handles a problem if the implant becomes painful or loose between visits, since you may need a local dentist willing to examine someone else's work.
Records you should leave with
- Before-and-after X-rays of the treated tooth.
- For a root canal: which canals were treated and with what materials.
- For an implant: the brand, model, diameter and length of the implant and the abutment type. A future dentist may need these to source compatible parts.
Ask for these at your final appointment rather than by email weeks later. Clinics are usually able to hand over digital copies on the spot, and having them before you fly avoids a frustrating chase if you need care at home.
Questions to ask before you decide
- What is the realistic prognosis for this tooth if I save it?
- Is there a crack, and if so, does it extend into the root?
- Would you refer me to an endodontist for a second look before extracting?
- If we extract, can the implant go in the same day or do I need to heal or graft first?
- What will my total cost be for each path, including the crown?
- What happens, and who pays, if the treatment fails?
- How many visits does each path need, and can any be done closer to home?
Bottom line
When an infected tooth can be predictably restored, root canal treatment keeps your natural tooth with fewer visits, no surgery in the usual case and a lower upfront cost. When the tooth is cracked into the root, badly broken down or poorly supported by bone, extraction and an implant may offer a more dependable long-term result despite the longer timeline. The deciding factor is the condition of the specific tooth, which only a dentist examining it with imaging can judge. If the recommendation is extraction and you are unsure, a second opinion from an endodontist before the tooth comes out is reasonable, because extraction cannot be undone.

Frequently Asked Questions
Is a root canal more painful than having a tooth pulled?
Both are done under local anesthesia, and the ADA says a root canal involves little to no pain during treatment. Afterward, a root canal typically brings a few days of soreness, while an extraction followed by implant surgery involves healing of the socket and later the implant site. Individual experiences vary.
Do I always need a crown after a root canal?
Not always. The ADA notes the final restoration may be a filling or a crown, depending on how much healthy tooth remains. Back teeth that chew heavily and teeth with large fillings are more often crowned. Your dentist will base the choice on the remaining structure.
What does an endodontist do that my general dentist does not?
An endodontist is a dentist with additional specialty training focused on the inside of the tooth, including complex root canals, retreatment and minor surgery at the root tip. If you are told a tooth cannot be saved, an endodontist can offer a focused second opinion.
Can a tooth that already had a root canal get infected again?
Yes, it can happen, for example if bacteria leak back in under a failing filling or crown, or if a canal was missed. Options may include retreatment, surgery at the root tip or extraction. Your dentist will judge which is realistic from X-rays and an exam.
Can I get the implant placed the same day the tooth is removed?
Sometimes. Placing an implant at the time of extraction depends on factors such as active infection, the amount of bone available and the location of the tooth. In other cases, the dentist waits for healing or grafts bone first. Ask which sequence fits your situation and why.
