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.

Im terrified of the dentist but after my first visit, im already looking forward to the next!

I had dentures made at Aspen in Keene and it was a disaster. I would rate them as a zero. But a couple years later Lost a tooth and grimaced at the thought of going back. Instead I went to Leominster. What a difference! I was greeted with a professional staff th at took care of me quickly. The dentist that took care of me was awesome I had worried about the price, I thought is is when they get me, but she came back and told me to come back in a couple hours and they’d have it fixed at no charge, it’s still under a 7 year warranty, that was not mentioned in Keene. The repair was perfect , you couldn’t notice at all! If you need dental work, this is the place to go!

What a great experience with wonderful staff. Samone was very kind putting me at ease right away and explaining the xray she was going to to take. Samone introduced me to the staff as if they were one big family there to take care of me. Going in i was nervous not knowing what to expect but when I left I was informed of all options. The office manager Chris was able to fit me in the same day so I wouldn't be in pain anymore!!

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.
