What Is Root Canal Therapy?

Root canal therapy is a dental procedure designed to treat infections in the tooth's pulp, the soft tissue inside the root canal containing nerves, blood vessels, and connective tissue. Treatment involves removing the infected or damaged pulp, carefully cleaning and shaping the root canal system, and then filling and sealing it. That seal prevents further infection from taking hold inside the tooth. Our experienced dentist uses advanced techniques and state-of-the-art technology throughout. The goal is always to save your natural tooth and relieve the pain that decay or infection caused.

The Benefits of Root Canal Therapy

Tooth Preservation

Root canal therapy preserves your natural tooth and avoids the extraction that would otherwise be the only remaining option available to you at this stage.

Pain Relief

Treatment eliminates the pain and discomfort caused by an infected pulp and restores normal biting force to that part of your mouth again at every single meal.

Infection Control

Removing the infected pulp prevents that infection from spreading into the surrounding bone or into any of the neighboring teeth around it and into the tissue surrounding it.

Protected Neighbors

Saving the tooth protects the surrounding teeth from shifting and supports better long-term oral health across your whole mouth for many more years than otherwise.

Our Step-by-Step Process

Here is what to expect during root canal therapy at Smile Tustin by Dr. Ezzy.

Request an Appointment
  1. 01

    Examination Imaging

    Our experienced dentist examines the tooth and takes X-rays to confirm the extent of the infection inside it before any treatment gets underway.

  2. 02

    Comfortable Numbing

    Local anesthetic numbs the tooth completely, and a dental dam isolates it to keep the whole area clean and dry throughout the entire procedure.

  3. 03

    Pulp Removal

    A small access opening is made in the tooth, and the infected or damaged pulp is carefully removed from the chamber from inside the tooth itself.

  4. 04

    Canal Cleaning

    The root canal system is cleaned and shaped thoroughly, which clears out the bacteria causing the infection along with any remaining debris.

  5. 05

    Filling & Sealing

    The canals are filled and sealed to prevent any further infection, and a crown then restores the tooth afterward and protects it for the long term.

Signs You May Need a Root Canal

  • Severe Toothache — A severe toothache flares when you chew or apply pressure, which often points to infection deep in the pulp at the very center of the tooth.

  • Abscessed Tooth — An abscess has formed around the tooth, and that infection now risks spreading through your mouth and face and could become a medical emergency.

  • Lingering Sensitivity — Sensitivity to hot or cold lingers on long after the food or the drink that caused it has left your mouth entirely, which suggests nerve damage.

  • No Symptoms — The tooth does not hurt at all right now, but a compromised nerve means symptoms may not be relayed properly back to you the way they should.

What Our Patients Say

  • I had such a fantastic experience at Dr. Ezzy's office! From the moment I walked in, I was greeted warmly by the front desk staff who made me feel completely at ease. The office was clean, modern, and had a very calming atmosphere. Dr. Ezzy was not only incredibly professional but also kind, patient, and thorough. They took the time to explain every step of the process and answered all of my questions without rushing. I felt genuinely cared for, not just like another appointment on the schedule. The hygienist did a wonderful job with my cleaning—gentle yet effective—and made sure I was comfortable the entire time. Even the X-rays and exam were quick and painless. I especially appreciated how transparent they were about my dental health and any recommended treatments. No pressure—just honest advice. I left feeling confident, cared for, and actually looking forward to my next visit (which I never thought I’d say about the dentist!). Highly recommend this office to anyone looking for quality care with a personal touch!

  • I had a major gum issue that may have led to significant dental work like a root canal and a crown or even an implant However the good team at Smile Tustin took some x-rays as well as a 3-D image and with the expert help of an orthodontist determined that only an antibiotic was necessary The gum infection was eliminated and no further dental work was needed I was in good hands of the Smile Tustin dental team Feel confident and comfortable leaving your dental issues in their hands

  • Dr.Ezzy is diligent, professional, caring. I appreciate the amount of information and options Dr. Ezzy provides regarding potential treatments without trying to 'sell' a particular plan. Also appreciate the amount of time spent explaining options and treatments. In addition I truly appreciate hygienist Vicki for her excellent cleaning skills and most importantly, she is extremely considerate, kind, professional and conveys a feeling of genuine care for her patients. Office staff also very professional and offer great communication and support. Great team, highly recommend!

  • As a new patient I got an appt a few weeks out but they promised to call if something opened up and 2 days later I had my first appt! I have not had a good experience at multiple other locations which try to sell you all kind of nonsense treatments, so I have not been to the dentist for a very long time avoiding all the nonsense. I went for my appt and staff is super friendly, they spent quite a while cleaning (since I was looong overdue for that), and I can not be more happy with the result and the service provided! Awesome staff, excellent work, no nonsense, happy to come back text time around.

  • I can’t say enough good things about my experience with Dr. Ezzy. From scheduling the appointment to the actual visit, everything was smooth and stress-free. The team is friendly, organized, and genuinely cares about patients. Dr. Ezzy is not only highly skilled but also very kind and reassuring, which made a big difference for me. They took the time to listen to my concerns and made sure I felt comfortable every step of the way. The treatment was quick, painless, and done with great attention to detail. It’s rare to find a dental office that combines professionalism with such a warm and welcoming atmosphere. I’m really grateful to have found Dr. Ezzy and would confidently recommend them to anyone looking for top-quality dental care.

  • They are extremely tech-advanced and properly staffed. I really wish I had found them sooner. In life, you have to switch to a dentist that can provide you with proper care including having staff properly respond. Shout out to Debbie, she sealed the deal for me not because of sales skills but because of patient education and also having a seven year old CEREC crown herself. Even basic things like X-rays and numbing are done so much better here than at any other office I’ve been to. I already got a same-day CEREC crown here, and they also offer financing options. I do have several cavities and may need more crowns in the future (based on x rays from my previous dentist)—not because they are pushing treatment, but because I’ve had long-standing dental issues from large childhood fillings and nerve involvement. I’ll need to get an x ray here when I’m back and see what options they can provide to me. Maybe there are other ways. I finally found a place I trust with my long-term dental health. It’s been depressing finding one problem after another, but I feel genuinely safe starting treatment here. The staffing is especially important, because for urgent care, education, and follow-up, this is the first office that has truly met those needs.

  • I had an onlay made for a tooth that lost a filling. Such a pleasant experience. Perfect shade. No pain, no problems. Conservative treatment. Dr Ezzy is a perfectionist with a caring touch and great "bedside" manners. I had my teeth cleaned the following day and again a thorough job. Dr Ezzy has a great staff, kind, informative and professional. I highly recommend!

  • I found Dr. Ezzy through an internet search after not being too happy with another dentist. I contacted them and was given the white glove concierge treatment from the first point of contact. Just had my first treatment done last Monday. It was done in a very efficient, competent and kind way. We have found our permanent dentist. Thanks Team Smile Tustin!

Frequently Asked Questions
About Root Canal Therapy

Don't see the answer you're looking for? Call us at (714) 730-5600.

Do I need a root canal without any pain?

Yes, because the nerve of the tooth is compromised, it may not relay symptoms properly. You could have a severe infection or a dying tooth without ever feeling it.

What happens if an abscess goes untreated?

An abscessed tooth can continue to spread infection throughout the mouth and face. In serious cases, it can even lead to a medical emergency.

Is a root canal better than an extraction?

Saving your natural tooth preserves normal biting force and protects the teeth around it. Extraction removes the problem but creates a gap that then needs replacing.

How much does root canal treatment in Tustin, CA, cost?

The cost depends on which tooth is involved and the complexity of its canals. Our team reviews the full fee with you before treatment begins.

Does insurance cover root canal treatment in Tustin, CA?

Most dental plans cover a portion of endodontic treatment. Our front office will verify your benefits and explain what your plan covers.
