How long does a root canal take?

Most root canals take about 1–2 hours. The exact time depends on which tooth is being treated and how complex the infection is. Your Aspen Dental care team will walk you through the plan before starting, so you know what to expect and can plan your day around it.

Thanks to modern anesthesia and techniques, we try to help our patients feel as comfortable as possible. You may notice some soreness or sensitivity afterward, but that can usually be managed with over-the-counter medication or instructions from your care team.

Is root canal treatment an emergency?

In many cases, it can be. If the infection of the root canal inside your tooth spreads, it may affect nearby teeth, gums or even bone. That’s why it’s important to get care quickly when you notice lingering pain or swelling. Aspen Dental offers same-day appointments in many locations to treat urgent needs.

How long do root canals last?

With proper care, a root canal can last decades. After the procedure, your Aspen Dental dentist may recommend a crown to protect the tooth and restore strength. Good oral hygiene and regular checkups all play a role in keeping the treated tooth healthy long term.

Had a terrible infection in my mouth literally size of a golf ball almost because of two broken teeth these guys did me absolute justice a year ago probably the reason I’m here now so thank you

Everyone at this Aspen Dental office was friendly and on top of things! The team and doctors were patient and shared helpful insights and resources that made the whole process feel much less overwhelming. You can tell they really care. I want to acknowledge their operations manager, Jamie. She was incredibly kind and genuinely helpful. During the consultation, she took the time to work around our very busy schedule and still got us in for everything we needed within the short window we had. She’s really great and organized! Overall, the team at the Aspen Dental Festus office was fantastic!

I have been to three Aspen locations and can honestly say that Festus is the best! The Operations manager Jaime knows her stuff! She's went above and beyond to help me with my dental journey. Everyone at the Festus location has been wonderful to me. Thank you Festus team!!

What is a root canal?

A root canal is an endodontic treatment that cleans infection inside your tooth so we can save it instead of taking it out. If left untreated, the pulp that has nerves or tissue may die as a result of infection. Left untreated, an infected tooth can cause damage and lead to other issues. At Aspen Dental, your comfort is our priority at every step—we’ll explain everything and keep you comfortable throughout the process. If cost is what’s holding you back, don’t delay your visit—we accept most insurances and financing options—so you’ll know exactly what to expect.
