A root canal removes infected or inflamed tissue from inside a tooth and seals it, and most of these treated teeth last for many years. Sometimes, though, a root canal fails. Common warning signs include pain when biting, swelling, a small pimple-like bump on the gum, or a tooth that darkens. Not every failed root canal means losing the tooth, but sometimes an implant becomes the more reliable path. Below are seven reasons that can happen, followed by five northern Utah practices to consider, starting with Stubbs Dental, which places single implants.
Why might a failing root canal lead to an implant?
1. Is the root cracked?
A vertical root fracture, a crack running lengthwise down the root, is one of the most common reasons a root-canal-treated tooth cannot be saved. These cracks generally cannot be repaired, and the usual treatment is removing the tooth. An implant can then replace it.
2. Is there enough tooth left to rebuild?
Teeth that have had a root canal are often already weakened by decay or large fillings. If too little healthy structure remains above the gumline to hold a new crown securely, the tooth may be considered non-restorable, and replacing it becomes the more predictable choice.
3. Has the infection come back after retreatment?
A failed root canal can sometimes be redone, a procedure called retreatment. If infection returns even after retreatment, the chances of another attempt succeeding drop, and removing the tooth may be the best way to clear the infection for good.
4. Is the bone or gum around the tooth breaking down?
Advanced gum disease or infection can destroy the bone that supports a tooth. When too much support is lost, the tooth may loosen no matter how well the root canal itself was done.
5. Is the root being damaged from inside or out?
Resorption is a process in which the body breaks down part of the tooth’s root. A perforation is an accidental opening through the side of the root. Depending on size and location, both can make a tooth difficult or impossible to keep long term.
6. Would saving the tooth cost nearly as much as replacing it?
Retreatment, a new post, and a new crown can add up. When the prognosis is uncertain, some patients choose to put that money toward an implant, which replaces the tooth with a root that cannot decay or need another root canal.
7. Do you need the most predictable long-term result?
An implant fused to healthy bone can last for decades with good care. When a tooth has already failed once and the outlook for retreatment is guarded, an implant may offer a steadier long-term result.
When can the tooth still be saved?
Often. Retreatment or a minor surgery called an apicoectomy, which removes infected tissue at the root tip, can save many teeth with failed root canals. An endodontist, a dentist specializing in root canal care, can assess whether yours is one of them. Ask about both paths before deciding.
Which northern Utah practices can replace a tooth that cannot be saved?

1. Stubbs Dental
Dr. David Stubbs, DDS, founded Stubbs Dental Implant Center in 2014. He earned his degree at the University of the Pacific Arthur A. Dugoni School of Dentistry and received post-graduate clinical training as a U.S. Navy officer. The practice places single implants, including metal-free zirconia implants, for patients whose damaged tooth needs to be replaced.
The practice also handles the steps that often come first, including tooth extraction and bone grafting when infection has thinned the bone. A free consultation includes a 3D CBCT scan to evaluate the root and surrounding bone. Offices are located in Layton, Bountiful, Murray, and Lehi.

5. Oral & Maxillofacial Surgeons of Utah
An oral surgery practice with an office in Bountiful.
What should you do if your root canal is failing?
Do not wait for the pain to settle on its own, because a lingering infection can damage the bone you may need later. Get the tooth evaluated with a 3D scan, ask whether it can be saved and what that would involve, and compare that plan with an implant. Then book a consultation and choose the path with the best long-term outlook for you.
