Modern technology and sedation options make the procedure more comfortable than ever.

Root Canal Treatment

When the soft tissue inside your tooth, called pulp, becomes infected or inflamed, root canal treatment is necessary to save the tooth and eliminate pain. Without this procedure, the infection spreads, the pain worsens, and extraction becomes the only option.

Root canals at Thompson Dental preserve your natural tooth, protect your oral health, and relieve the severe pain that often comes with an infected tooth.

Root Canal Treatment Stops the Pain

Many people fear root canals based on outdated information. The truth is that modern root canal treatment doesn't cause pain; it relieves it.

As your trusted root canal dentist, Dr. Sean and Dr. Zachary prioritize your comfort and well-being throughout the entire process. We offer multiple sedation options to ensure you feel relaxed and at ease, even if dental anxiety has kept you from seeking treatment.

Sedation Dentistry Options for Complete Comfort

We understand many dental procedures can feel intimidating, whether it's root canal treatment, extractions, implant placement, or even routine cleanings for patients with severe anxiety. That's why we offer multiple sedation options to help you feel relaxed and comfortable throughout any procedure.

Nitrous Oxide (Laughing Gas)

This mild sedative is inhaled through a small mask during treatment. It creates a relaxed, calm feeling, but you will remain fully conscious and able to respond to our team. The effects wear off quickly after we remove the mask, so you can drive yourself home and resume normal activities immediately.

Oral Conscious Sedation

You'll take a prescribed medication before your appointment that produces deeper relaxation than nitrous oxide. While you remain awake and able to respond, you'll feel drowsy and may have little memory of the procedure afterward. You'll need someone to drive you to and from your appointment.

Deep Sedation with an Anesthesiologist

For patients with severe dental anxiety or complex cases, we partner with a licensed anesthesiologist who administers deep sedation. You'll sleep through treatment while the anesthesiologist monitors your vital signs. This option requires a driver to get you home safely.

Frequently Asked Questions

What happens if I don't get a root canal?

When Dr. Sean or Dr. Zachary recommends root canal treatment, it means the nerve inside your tooth is infected or severely inflamed. Ignoring this problem won't make it go away. It will only get worse, and the consequences can be quite serious.

Immediate Consequences

Without treatment, the infection will continue spreading through the tooth's root canals and into the surrounding bone. Pain typically worsens, making it difficult to eat, sleep, or concentrate. The tooth may become increasingly sensitive to hot and cold.

Severe and Systemic Complications

As infection progresses, an abscess can form, which is a pocket of pus at the tooth's root, causing severe swelling, fever, and intense pain. Abscesses can spread to your jaw, neck, or face, creating life-threatening conditions that require emergency hospitalization.

More Complex and Costly Treatment

Delaying root canal treatment often means losing the tooth entirely, requiring extraction followed by implant placement, a bridge, or partial denture to replace it. All these procedures are significantly more expensive than the original root canal and crown.

The sooner you address the problem, the simpler and more affordable the treatment will be. Call Thompson Dental at (949) 558-0111 to schedule an appointment. We serve patients from Laguna Niguel, Dana Point, Aliso Viejo, Laguna Hills, Laguna Woods, Mission Viejo, and South Orange County.

The Root Canal Treatment Process

Root canal treatment typically takes one to two appointments, depending on the complexity of your case:

Numbing the area thoroughly so you feel no pain during the procedure. If you've chosen sedation, we administer that before we begin treatment.
Placing a rubber dam around the tooth to keep it clean and dry during the procedure
Creating a small opening in the top of your tooth to reach the infected pulp chamber
Carefully removing the infected or inflamed pulp from inside your tooth
Cleaning and shaping the root canals using advanced rotary endodontic instruments, we clean and shape the root canals. This technology is gentler and more efficient than traditional hand files, and makes the process faster and more comfortable.
Filling the cleaned canals with a biocompatible material called gutta-percha to seal them and prevent future infection
Placing a temporary filling to protect the tooth until we place your permanent restoration
Placing your final restoration, usually a crown, to protect the tooth and restore full function

After your root canal, you may experience mild discomfort for a few days. This sensation is perfectly normal, and over-the-counter pain medication is usually enough to relieve any sensitivity.

Root Canal Treatment Technology

Rotary Endodontics

Rotary endodontic instruments are precision-engineered files that clean and shape root canals more efficiently than traditional hand files. These nickel-titanium instruments are powered by a quiet electric motor and flex to follow the natural curves of your tooth's root system. The result is more thorough cleaning, reduced treatment time, and improved success rates. Root canal therapy is more comfortable and predictable when we use advanced rotary techniques.
