Few dental procedures carry as much undeserved anxiety as the root canal. At its core, a root canal simply involves removing infected or damaged pulp from inside a tooth, cleaning and disinfecting the root canals, and sealing the tooth to prevent reinfection. Modern endodontic care has transformed this once-dreaded procedure into a routine, comfortable experience that most patients compare to getting a filling.
At Excel Endodontics in Marlboro, NJ, our team performs root canal treatment using Surgical Operating Microscopes and Cone-Beam CT (CBCT) imaging—making every step more precise and comfortable. We also offer nitrous oxide (laughing gas) for patients who need extra reassurance. Here is a clear, step-by-step breakdown of what actually happens during a root canal.
Why Teeth Need Root Canal Treatment
How Dental Pulp Becomes Infected
Every tooth contains a soft inner core called the pulp, which holds nerves, blood vessels, and connective tissue. When bacteria penetrate the pulp—through a deep cavity, a crack, a chip, or trauma—an infection develops. Left untreated, that infection spreads into the surrounding bone and can cause a painful abscess.
Common Warning Signs to Watch For
Symptoms vary, but common indicators that a tooth may need endodontic treatment include:
- Persistent, throbbing tooth pain, sometimes radiating to the ear or jaw
- Severe sensitivity to hot or cold that lingers after the source is removed
- Pain when biting or chewing
- Darkening or discoloration of the tooth
- Swollen or tender gum tissue near the affected tooth
- A small pimple-like bump on the gum (a sign of drainage from an abscess)
Occasionally, a tooth that needs treatment shows no symptoms at all, and changes on a dental X-ray serve as the only indicator—one reason routine imaging matters.
Step 1: Examination, Imaging, and Anesthesia
How Our Endodontist Assesses the Tooth Before Treatment
Before starting any procedure, our endodontist conducts a thorough clinical examination and reviews diagnostic imaging. We use Cone-Beam CT (CBCT) technology, which produces detailed three-dimensional scans of the tooth and surrounding structures. Standard two-dimensional X-rays can miss curved canals, hidden fractures, or complex anatomy—CBCT eliminates that guesswork and allows for a more accurate treatment plan.
What Getting Numb Actually Feels Like
Once we confirm the diagnosis and discuss the plan with you, we administer local anesthesia to numb the area fully. Most patients feel a brief pinch during the injection, then nothing at all. For patients with dental anxiety, we offer nitrous oxide (laughing gas), which takes effect quickly, promotes calm, and wears off immediately after we turn it off—so you can drive yourself home.
Step 2: Isolation and Access
Preparing the Tooth for Treatment
After the tooth is fully numb, we place a rubber dam around it to keep it dry and saliva-free and to stop debris from being swallowed. We then create a small opening through the crown of the tooth to access the pulp chamber. A Surgical Operating Microscope illuminates and magnifies the interior, allowing our endodontist to locate all canal openings—including fine or calcified canals that the naked eye could easily miss.
Step 3: Removing the Pulp and Cleaning the Canals
What Happens Inside the Tooth
With the tooth open and fully numb, our endodontist uses small, flexible instruments to remove the infected or inflamed pulp tissue from the pulp chamber and each root canal. The number of canals varies by tooth—front teeth typically have one, while molars can have three or more. We then shape each canal with progressively larger files and irrigate with antibacterial solutions to flush out remaining bacteria and debris. Finally, a laser is used for enhanced cleaning and disinfection of the canal space.
Step 4: Sealing the Tooth
Filling and Restoring the Tooth
Once the canals are clean, shaped, and dry, we fill them with a biocompatible rubber-like material called gutta-percha, which—combined with a sealing cement—blocks bacteria from re-entering. We close the access opening with a temporary or permanent filling.
What to Expect After Your Root Canal
Most patients return to normal activity the same day. Mild soreness for a few days is common and typically responds well to over-the-counter pain relievers. We recommend avoiding hard, crunchy, or sticky foods on the treated side until the permanent restoration is in place. Most patients find recovery considerably easier than they expected—especially compared to the pain that preceded treatment.

Frequently Asked Questions About Root Canal Treatment
Does a root canal hurt during the procedure?
No. Modern local anesthesia and endodontic techniques make the procedure virtually pain-free. Most patients report feeling pressure or movement but no sharp pain. For anxious patients, we offer nitrous oxide (laughing gas) to promote relaxation throughout the appointment.
How long does a root canal procedure take at Excel Endodontics?
Treatment time depends on the complexity of the case and the number of canals involved. Straightforward root canals typically take anywhere from 30 to 60 minutes. More complex cases may require an additional appointment. Our endodontist will give you a realistic timeline after evaluating your CBCT imaging and clinical findings.
Can I drive myself home after a root canal?
Yes, in most cases. Local anesthesia does not impair your ability to drive. If you choose nitrous oxide, the gas wears off completely within minutes of being turned off, so driving yourself home remains safe.
What happens if I delay or avoid root canal treatment?
A pulp infection does not resolve on its own. Without treatment, bacteria spread through the root canal system and into the surrounding bone, potentially causing a dental abscess, bone loss, and eventually tooth loss. Early treatment prevents these complications and preserves your natural tooth.
What is the difference between a general dentist and an endodontist performing a root canal?
Endodontists complete two to three years of advanced postgraduate training focused exclusively on diagnosing and treating conditions of the dental pulp and root systems. They perform root canals far more frequently than general dentists and use specialized equipment—such as Surgical Operating Microscopes—that many general dental offices do not have.
