Endodontics · Dublin, California

Root canal therapy — gentler than its reputation, and the reason a tooth stays.

A precise, predictable procedure that saves a tooth whose internal nerve has become infected or inflamed. Performed under careful local anesthetic, very often under a surgical microscope, and routinely described by our patients as “easier than the cleaning I had last year.”

Quick answer A root canal (endodontic treatment) is a restorative procedure in which the infected or inflamed nerve tissue inside a tooth is carefully removed, the inside of the tooth is cleaned and shaped, and the canal is sealed with a biocompatible material. At Dublin Ranch Dental in Dublin, California, Dr. Prajesh Desai performs root canal therapy under local anesthetic, often using a surgical microscope for precision. Most patients describe the experience as comfortable and routine. A crown is typically placed afterward to protect the treated tooth long term. Every case is planned and priced individually.

Why a tooth needs a root canal in the first place

The hard, white outside of a tooth is enamel. Underneath is dentin, and at the center of the tooth is the pulp — a small chamber of soft tissue containing nerves and blood vessels. When the pulp becomes infected (deep decay, a deep crack, repeated dental work, or trauma), the body cannot resolve the infection on its own; the result is pain, sensitivity to temperature, and eventually a dental abscess. Root canal therapy removes the infected pulp, sterilizes the space, and seals it, so the tooth can stay in your mouth for the rest of your life.

The most important framing: a root canal saves a tooth that would otherwise be lost. Extracting and replacing a tooth is more invasive, more expensive, and more disruptive than performing a careful endodontic treatment. The procedure has come a long way; modern endodontics is not the experience most people remember from a generation ago.

Signs you may need a root canal

  • A persistent toothache that lingers after the trigger is gone
  • Sharp sensitivity to hot or cold that does not fade in seconds
  • Pain when biting down on a specific tooth
  • A pimple-like bump on the gum near the tooth (a sinus tract)
  • A darkened tooth, especially a front tooth
  • Swelling around a tooth or jaw, sometimes with a faintly bad taste
  • A tooth that has had a recent trauma even if the visible damage was minor

Any of these warrant a visit. Caught early, a root canal is a one-visit, comfortable, predictable procedure. Caught late, an abscessed tooth is a more difficult conversation.

How the procedure actually goes

  1. Diagnose. A focused exam, digital X-rays, and (when warranted) a CBCT 3D image to confirm exactly which tooth and which canals are involved.
  2. Numb. Careful local anesthetic. Modern delivery techniques mean the numbing itself is gentle.
  3. Isolate. A small protective sheet (a rubber dam) is placed around the tooth to keep the working field perfectly clean.
  4. Clean. Working under high-magnification (often the surgical microscope), Dr. Desai gently cleans the inside of the tooth using fine instruments and bacteriostatic irrigation.
  5. Seal. The canal is filled with a biocompatible material called gutta-percha, sealed against bacteria.
  6. Restore. A temporary or definitive restoration is placed; a final ceramic crown follows in a separate appointment (often CEREC same-day in our office) to protect the tooth long term.

Comfort and sedation

For nervous patients, nitrous oxide or oral conscious sedation are available; many patients prefer them and find the appointment passes effortlessly. For most patients, however, local anesthetic alone is plenty — modern root canal therapy is genuinely a routine experience.

Why we use a surgical microscope

The internal anatomy of a tooth is small, variable, and sometimes surprising. Magnification under a true surgical microscope means we can see what an unaided eye cannot — an accessory canal, a hairline crack, a calcification — and treat what we find. Microscopic endodontics is the single technique most strongly correlated with long-term root-canal success in the published literature.

Will I need a crown afterward?

Almost always, yes. A tooth that has had a root canal is structurally weaker than before; a properly designed crown is what allows it to stay in service for decades. Skipping the crown is the most common reason root canal teeth fail later. For most cases, we place the final ceramic crown the same week using CEREC.

About investment & financing

Every root canal case is planned and priced individually. What we will commit to up front: a written treatment plan before any work begins, with line-item fees for the endodontic treatment, the build-up, and the final crown if needed. We’re flexible about pacing and offer CareCredit, Sunbit, in-house monthly arrangements, and HSA/FSA. Most dental insurance covers a portion of endodontic therapy; our front office will pre-verify your benefits before the appointment.

Frequently asked

How long does a root canal take?

Most single-tooth cases are completed in a single 60–90 minute appointment. Molars (with more canals) sometimes take a touch longer. Complex cases may be split across two visits.

Is a root canal painful?

No — the procedure itself relieves pain. With modern anesthetic, careful technique, and (when desired) sedation, the experience is comfortable. The discomfort patients remember as “a root canal” is almost always the infection that preceded it.

Can I drive home afterward?

Yes, unless you’ve chosen oral or IV sedation, in which case we’ll ask you to arrange a ride.

How long will a root-canal tooth last?

Decades. A well-performed root canal followed by a properly designed crown has a long-term survival rate above 90%. We back our restorative work with a written warranty.

What does a root canal cost at Dublin Ranch Dental?

Honestly, it depends. The cost of endodontic therapy varies by which tooth is involved, how many canals it has, and whether any rebuild work or crown is required. Every case is planned and priced individually; come in, we’ll examine, and you’ll leave with a written, itemized plan and a real conversation about how to make it work.
