If the words “root canal” make you tense up, you are not alone, but the procedure has a far worse reputation than it deserves. At Smile Roots Dental, Dr. Jin Song Yom, DDS brings over 16 years of experience performing root canal therapy with a level of precision and efficiency that consistently surprises even the most anxious patients. Her goal is simple: get you out of pain, save your tooth, and make the whole experience feel nothing like you feared.
Root Canal Therapy
How Tooth Infections Progress Without Treatment
A tooth infection does not stay put. It starts when bacteria work their way through a cavity, crack, or damaged filling and reach the pulp, the soft inner tissue that houses the tooth’s nerves and blood vessels. Once bacteria reach that layer, the pulp becomes inflamed and infected. The pain you feel is your body signaling that something is wrong deep inside the tooth, not just on the surface.
Without treatment, the infection continues to spread. The pulp dies, but the bacteria do not stop there. They move into the root canals and eventually into the surrounding bone. What started as a toothache can become an abscess, bone loss, or an infection serious enough to affect neighboring teeth. Root canal therapy interrupts that progression. It removes the infected tissue, cleans and seals the canals, and gives the tooth a real chance at long-term survival before the damage becomes irreversible.
Benefits of Root Canal Therapy
Numbing Technology Makes the Procedure Far More Comfortable Than Expected
The biggest misconception about root canal therapy is that the procedure itself is painful. Modern local anesthesia fully numbs the tooth and surrounding area before anything begins. What most patients actually feel during treatment is pressure, not pain, which is a very different experience from what they anticipated. For many, the relief that follows is far greater than any discomfort during the procedure.
Treated Teeth Do Not Develop New Infections in the Same Spot
Once the pulp is removed and the canals are thoroughly cleaned and sealed, there is no living tissue left inside the tooth for bacteria to infect again. The sealing material fills the canals completely, cutting off the pathway bacteria used to cause the original infection. A properly completed root canal significantly reduces the chance of reinfection in that same tooth.
Removes the Nerve Without Removing the Tooth
Many patients are surprised to learn that a tooth can survive without its nerve. The nerve inside an adult tooth serves mainly sensory functions, telling you when something is hot or cold. Removing it through root canal therapy eliminates pain signals from that tooth without affecting its structural integrity. The tooth remains anchored in place and continues to function normally.
Stops Temperature Sensitivity That Disrupts Daily Life
Lingering pain when drinking hot coffee or biting into cold food is a common sign of pulp damage. That sensitivity does not resolve on its own once the nerve is compromised. Root canal therapy removes the damaged pulp responsible for those sharp, uncomfortable reactions, restoring your ability to eat and drink without bracing for pain every time.
Keeps Your Treatment Plan Simple By Addressing the Problem Once
A tooth that has reached the point of needing root canal therapy will not improve with temporary fixes like antibiotics or fillings over the infected area. Those approaches manage symptoms without solving the underlying problem, which means more visits, more procedures, and more expense over time. Root canal therapy resolves the issue in a single course of treatment, so you are not repeatedly returning for the same tooth.

What Dr. Yom Looks for During Your First Visit
Dr. Yom does not rush your first appointment. She reviews your dental and medical history, takes X-rays, and examines the affected tooth carefully before drawing any conclusions. What she finds, she tells you directly: what is happening, why it is happening, and what your options are. If she recommends root canal therapy, she will explain exactly why. And if you want a second opinion, she encourages it, because she is that confident in her diagnosis.
How Dr. Yom Decides the Right Course of Treatment
Not every infected tooth presents the same way, and Dr. Jin Song Yom does not treat them as if they do. She considers the location of the tooth, the extent of the infection, the condition of surrounding teeth, and your overall oral health before mapping out a plan. You will know the full scope of treatment before anything is scheduled, what each step involves, what it will cost, and what comes after. No surprises.
Precision, Speed, and Comfort in Every Procedure
Dr. Yom is known throughout San Diego for performing root canal therapy with a level of speed and accuracy that her patients consistently remark on. The tooth is fully numbed before she begins, and she narrates each step as she works so you are never left wondering what is happening. The infected pulp is removed, the canals are meticulously cleaned and shaped, and the tooth is sealed, all with the kind of efficiency that comes from 16 years of doing this exceptionally well.
How to Take Care of Your Tooth Once You Leave the Chair
Before you leave, Dr. Yom walks you through exactly what to expect in the days following your procedure and what you should do to support healing. Some tenderness around the treated area is normal and typically fades within a few days. She covers what to eat, what to avoid, and when to reach out if something does not feel right, so you leave the office informed, not guessing.
How We Check That Everything Is Healing Properly
A follow-up appointment gives Dr. Jin Song Yom the opportunity to confirm the tooth is responding well and, in most cases, place a permanent crown to fully restore it. This visit is not a formality. It is where the treatment is truly completed. She checks the surrounding tissue, reviews how the tooth feels under pressure, and addresses any questions that have come up since your procedure. Thorough care does not stop when you walk out the door.
Why Choose Our Approach to Root Canal Therapy
In over 20 years of practicing dentistry, Dr. Jin Song Yom has never received a single patient complaint. That is not a statistic she advertises lightly. It is the direct result of how she communicates. When something goes wrong, she tells you. When a procedure is unnecessary, she says so. When the diagnosis is uncertain, she encourages you to get a second opinion. That level of transparency is rare in any medical setting, and it is the standard every patient at Smile Roots Dental experiences from the very first visit.
For root canal therapy specifically, that honesty matters even more. It is a procedure that already carries anxiety for most people, and the last thing you need is a dentist who is vague about what is happening or why. Dr. Yom explains every step as she works, not just what she is doing, but why she is doing it. Paired with her technical precision and her ability to complete even complex cases efficiently, that combination is exactly why more than 350 patients are currently waiting to follow her to this practice. They are not just returning for dental work. They are returning because they trust her.
FAQs
How long does root canal therapy take?
Most root canal procedures take between 60 and 90 minutes, though the timeline depends on which tooth is being treated and how complex the case is. Molars with multiple canals naturally take longer than front teeth. In some situations, a second appointment is needed to place the final crown. An experienced dentist can often complete even difficult cases in a single, efficient visit.
What is root canal therapy?
Root canal therapy is a dental procedure that removes infected or inflamed pulp tissue from inside a tooth. Once the pulp is cleared out, the inner canals are cleaned, disinfected, and sealed to prevent bacteria from returning. A crown is typically placed afterward to restore the tooth’s strength and function. The goal is to save the natural tooth rather than extract it.
What to eat after root canal therapy?
Soft foods are the safest choice for the first day or two following treatment, such as yogurt, mashed potatoes, eggs, and soup. Avoid anything hard, crunchy, or chewy until sensitivity settles and your permanent crown is in place. Extremely hot or cold foods and beverages should also be avoided during initial recovery. Eating on the opposite side of the treated tooth helps protect the area while it heals.
Which condition requires root canal therapy?
Root canal therapy is typically needed when the pulp inside a tooth becomes infected or inflamed beyond the point of self-healing. Common causes include deep decay, a cracked tooth, repeated dental procedures on the same tooth, or physical trauma. Symptoms often include a persistent toothache, sensitivity to heat or cold that lingers, swelling near the gumline, or visible darkening of the tooth.
How much does root canal therapy cost?
Root canal therapy generally ranges from $700 to $1,500 or more, depending on the tooth being treated and the complexity of the case. Molars tend to cost more than front teeth due to the number of canals involved. Most dental insurance plans cover a portion of the procedure. Practices like Smile Roots Dental prioritize transparent pricing, so patients know exactly what to expect before treatment begins, with no surprise fees.
Honest Care for a Procedure Most People Dread
Most patients who have been through root canal therapy at Smile Roots Dental say the same thing afterward. They wish they had come in sooner. The procedure they dreaded turned out to be far more manageable than the weeks or months of pain they endured before it. That relief is real, it is lasting, and it is one phone call away. Dr. Jin Song Yom has spent over 20 years making sure patients leave her chair in better shape than when they walked in, and that does not change here.
If tooth pain has been interrupting your sleep, your meals, or your daily routine, you already know something needs to be done. The only question is when. Dial 619.304.5000 to speak directly with the Smile Roots Dental team and take the first step toward feeling like yourself again.
