Extraction is the choice when the tooth cannot be saved. Each path has next steps, so ask your dentist to explain both. RestorativePublished October 26, 20264 min read ## Which is better for a back molar, a root canal or an extraction? Neither is better for every tooth. Cleveland Clinic says dental providers prefer to save natural teeth whenever possible, and that dentists usually recommend extraction when other treatments are not enough to save the tooth. So the first question is whether your [molar](https://towncenterdental.multisites.ai/glossary/molar) can be saved. Your dentist answers that with an exam and X-rays. A [root canal](https://towncenterdental.multisites.ai/services/root-canal), also called [root canal therapy](https://towncenterdental.multisites.ai/glossary/root-canal-therapy), treats an infected or badly inflamed tooth from the inside. MouthHealthy from the ADA says root canals are used to repair and save your tooth instead of removing it. A [tooth extraction](https://towncenterdental.multisites.ai/glossary/tooth-extraction) removes the whole tooth from its socket. ## What pushes a tooth toward one path or the other? Cleveland Clinic says dentists may recommend an extraction for a fractured tooth, advanced gum disease, an impacted tooth, crowded teeth, or severe tooth decay. MouthHealthy lists a deep cavity, repeated dental work on the same tooth, a cracked tooth, or an injury as ways the pulp can become infected and need a root canal. So the same molar can lead to either path. What matters is how much healthy tooth is left, how far the infection has spread, and what you want for the long term. Your dentist weighs these with you. ## How do the two options compare? Root canal Extraction Goal Save the tooth Remove the tooth What happens The dentist numbs the area, removes infected pulp, cleans and seals the canals The dentist numbs the area, loosens the tooth, and removes it from the socket Time About 60 to 90 minutes, sometimes more than one visit Usually 30 to 60 minutes for one tooth After Tooth needs a crown or filling to protect it Space remains, so you talk about replacement Recovery Most people recover in under a week Return to routine in 48 to 72 hours, jawbone heals over several weeks Possible setbacks The tooth may need re-treatment or removal Dry socket, delayed healing, infection The times and recovery notes come from Cleveland Clinic. Your own visit may differ. Ask the office what to expect for your tooth. ## Why does a molar need a crown after a root canal? A root canal removes the pulp, and the visit ends with a temporary filling. MouthHealthy says a follow-up visit replaces that temporary filling with a regular filling or a crown to protect the tooth from further damage. Cleveland Clinic adds that you should not bite down hard on the treated tooth until the final crown is in place. Your dentist can talk with you about the crown step before you start. ## What happens when a root canal does not work? Cleveland Clinic says root canals sometimes do not work if the damage is too severe. If that happens, the provider may treat the tooth again with another root canal, or remove it and replace it with an implant or bridge. Ask your dentist what signs would tell you the tooth is not healing, and when to call. A throbbing ache after treatment is one reason to call. ## What happens after an extraction? The socket heals from the bottom up. A [blood clot](https://towncenterdental.multisites.ai/glossary/blood-clot-socket-clot) forms first and protects the bone and nerves. Cleveland Clinic says that for a large tooth like a molar, it could take up to four months for the jaw to fully heal. Your dentist may place a bone graft in the socket to help prevent bone loss in the jaw. Then comes the question of what to do about the gap. Cleveland Clinic lists dental implants, dental bridges, and partial dentures as options that can restore appearance, function, and oral health. If you choose an implant, you will probably wait a few months while the socket heals. See our guide on [replacing a missing tooth](https://towncenterdental.multisites.ai/guides/replacing-a-missing-tooth) to compare. Good aftercare matters too. Your dentist will give you written steps for the first few days. ## What about cost? Cost often shapes this choice, and it should be part of the talk. Town Center Dental does not publish prices. The office gives each patient their own estimate, and you can ask for one before you decide. Include the later steps, such as a crown or a replacement tooth, so you can compare the full picture of each path and not only the first visit. ## What questions should you ask your dentist? - Can this molar be saved? What in the X-ray tells you that? - What are the odds I will need more work on it later? - If I choose a root canal, what will the crown step look like? - If I choose an extraction, what are my replacement choices, and when would I decide? - What happens if I wait? A clear plan helps you pick with confidence. The choice is yours, and you can ask for time to think unless there is an emergency. ## When is it urgent? An infected tooth can spread. Cleveland Clinic lists trouble breathing or swallowing, and facial swelling that is spreading toward your eye or neck, as reasons to seek emergency medical care. Call 911 or go to an emergency room if that happens.

Cleveland Clinic says dental providers prefer to save natural teeth whenever possible, and dentists usually recommend extraction when other treatments are not enough. Whether your molar can be saved depends on how much of it is damaged. Your dentist can examine it and talk with you about both paths. ### What happens if I pull a molar and do not replace it? Cleveland Clinic says that after an extraction your dentist can talk with you about replacement options such as an implant, a bridge, or a partial denture. These options can restore appearance and chewing function. Ask your dentist what is likely for your mouth if you leave the space empty. ### Can a root canal fail? Cleveland Clinic says root canals sometimes do not work if the damage is too severe. In that case the provider may treat the tooth again with another root canal, or remove the tooth and replace it with an implant or bridge. This is one reason to follow up after treatment. ### How long is recovery from each option? Cleveland Clinic says most people recover from a root canal in less than a week, with some lingering sensitivity. After an extraction, most people return to routine activities in 48 to 72 hours, though the jawbone takes several weeks to heal. Your dentist will give written steps. ## Terms on this page - [Gum disease (periodontal disease)](https://towncenterdental.multisites.ai/glossary/gum-disease-periodontal-disease) - [Dry socket (alveolar osteitis)](https://towncenterdental.multisites.ai/glossary/dry-socket-alveolar-osteitis) - [Blood clot (socket clot)](https://towncenterdental.multisites.ai/glossary/blood-clot-socket-clot) - [Cavity (dental caries)](https://towncenterdental.multisites.ai/glossary/cavity-dental-caries) - [Root canal therapy](https://towncenterdental.multisites.ai/glossary/root-canal-therapy) - [Temporary filling](https://towncenterdental.multisites.ai/glossary/temporary-filling) - [Tooth extraction](https://towncenterdental.multisites.ai/glossary/tooth-extraction) - [Fractured tooth](https://towncenterdental.multisites.ai/glossary/fractured-tooth) - [Impacted tooth](https://towncenterdental.multisites.ai/glossary/impacted-tooth) - [Crowded teeth](https://towncenterdental.multisites.ai/glossary/crowded-teeth) ## Sources 1.
