If your dentist has referred you for root canal treatment, you may feel anxious about what lies ahead. The good news: modern root canal therapy is far more comfortable than its reputation suggests. Most patients at Grandview Endodontics report the experience is no worse — and often better — than getting a routine filling.
Understanding each step of the process can help ease anxiety before your appointment. Here's a clear, honest overview of what happens during root canal treatment at our offices in Chino, Fontana, and Moreno Valley.
Before You Arrive
Before your procedure, our team will review your dental X-rays and health history. We may take additional digital X-rays or 3D cone beam CT scans to fully map the internal anatomy of the affected tooth and surrounding bone. This precise imaging is one of the key advantages of seeing an endodontist — we have access to advanced diagnostic tools that help us plan for even complex cases.
We recommend eating a light meal beforehand, as your mouth may feel numb for a few hours after the procedure. If you take any regular medications, continue them as normal unless advised otherwise.
The Procedure, Step by Step
Local Anesthesia
We begin by thoroughly numbing the tooth and surrounding area. We take our time to ensure you are completely comfortable before proceeding. Most patients feel only a brief pinch at the injection site.
Dental Dam Placement
A small rubber sheet (dental dam) is placed around the tooth to keep it clean, dry, and isolated from saliva during treatment. This helps maintain a sterile environment throughout the procedure.
Access Opening
A small opening is made in the top of the tooth to access the pulp chamber and root canals. This is done under a high-powered operating microscope for maximum precision.
Pulp Removal & Cleaning
Using specialized instruments, the infected or inflamed pulp tissue is gently removed. The root canals are then carefully shaped and thoroughly disinfected with antimicrobial solutions.
Canal Filling
Once cleaned and dried, the canals are filled with a biocompatible rubber-like material called gutta-percha, which seals the space and prevents future bacterial entry.
Temporary Seal & Referral
A temporary filling seals the access opening. You'll return to your general dentist within a few weeks for a permanent crown to protect and restore the tooth's full function.
What You'll Feel During the Procedure
With effective local anesthesia, you should feel no pain during the procedure — only occasional pressure or vibration from the instruments. If at any point you feel discomfort, let us know immediately. We can administer additional anesthetic to ensure your comfort throughout.
The procedure typically takes 60 to 90 minutes for a single-rooted tooth and may require a second appointment for teeth with complex canal anatomy (such as molars). Our endodontists will give you an accurate time estimate after reviewing your X-rays.
You are welcome to listen to music or a podcast during your visit — many patients find this helps them relax. Our team will communicate with you throughout and answer any questions as they come up.
A note from our team: The most common source of anxiety about root canals is the fear of pain — but research consistently shows that root canal treatment relieves pain rather than causes it. The infection in your tooth is the source of your discomfort; the procedure resolves it.
After Your Appointment
Once the anesthesia wears off (typically 2–4 hours after the procedure), you may experience mild soreness or sensitivity in the area. This is a normal inflammatory response and usually resolves within a few days. Over-the-counter pain relievers such as ibuprofen or acetaminophen are typically sufficient to manage any discomfort.
- Avoid chewing on the treated side until your permanent crown is placed
- Maintain your regular oral hygiene routine — brushing and flossing as normal
- Contact us if you experience severe pain, swelling, or a visible swelling in the gum area
- Schedule your follow-up with your general dentist promptly
The vast majority of patients return to work or normal activity the same day or the following day. Severe post-operative pain is uncommon when treatment is performed by an experienced endodontist.

Book Your AppointmentFrequently Asked Questions
Q: How long does a root canal take?
Most root canal procedures are completed in a single visit of 60–90 minutes. Teeth with multiple or complex canals (such as molars) may require a second appointment.
Q: Will I be awake during the procedure?
Yes — root canal treatment is performed under local anesthesia, so you are fully awake but cannot feel pain in the treated area. Sedation options are available for patients with dental anxiety; ask our team about what's right for you.
Q: When can I eat normally again?
We recommend waiting until the numbness has worn off before eating (to avoid accidentally biting your cheek or tongue). Until your permanent crown is placed, avoid chewing hard foods on the treated tooth.
