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.

⭐️⭐️⭐️⭐️⭐️ Five Stars — Truly Exceptional Care I don’t usually write reviews, but Aspen Dental absolutely deserves this one. I came in needing two teeth removed urgently due to infection, and from the moment I walked in, I was treated with real care and professionalism. Dr. P gave me the antibiotics and set the appointment to take care of my problems. Dr. P. was incredible — she removed the infected teeth I desperately needed taken out and did so with genuine compassion and skill. I never felt rushed or dismissed, and that meant a lot to me. The entire team was amazing: Jelena, Kristen, Emily, Brooke, and the office manager Jill all went above and beyond. They treated my situation seriously and professionally, and I truly felt like they cared about my well-being. What really stood out was that I had called several emergency dental services before this, and they all told me I had to bring cash. Aspen Dental actually worked with my insurance and with me to make sure I got the care I needed — and that made all the difference. I also want to give special recognition to the dental hygienist, Dr. Alex Grossman. She was outstanding. She took the time to explain everything clearly, answered my questions, and gave me a cleaning that I truly needed. She was extremely careful, thorough, and professional — honestly just excellent at her job. Overall, this was one of the best healthcare experiences I’ve had. Every single person I interacted with treated me with respect, patience, and genuine concern. If you’re looking for a dental office that puts patients first and delivers real, quality care, I can’t recommend Aspen Dental enough. Five stars without hesitation.

Root canal in Arnold, MO

If you’re dealing with ongoing tooth pain or infection, a root canal may be the recommended treatment. At Aspen Dental in Arnold, our care team provides root canal treatment close to home—so you don’t have to wait to feel relief.

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.
