Mercer Island's Root Canal Specialist, One Easy Exit East

Dr. Dejbod · one easy exit east of the island
In pain right now?
A dental emergency on Mercer Island shouldn't mean fighting into downtown Seattle and feeding a parking garage. Same-day same-day slots are reserved every business day — head east on I-90 instead, and be numb within the hour.
The Basics
What Root Canal Therapy Involves
The problem
Beneath the hard enamel, every tooth holds soft living tissue. A crack or deep cavity opens the door to bacteria, infection sets in, and the confined pressure produces pain that doesn't respond to willpower.
The treatment
Under a surgical microscope, Dr. Dejbod cleans the infected tissue out of each canal, disinfects the interior thoroughly, and seals it so bacteria stay out for good.
The outcome
Your natural tooth remains — anchoring bone, holding your bite, and sparing you an implant. Your Mercer Island dentist tops it with a crown, and that's the end of the story.
Specialist vs. Generalist
Why Eastside Dentists Refer to Dr. Dejbod
Dentists on Mercer Island and across the Eastside send their complex endodontic cases here for concrete reasons. The comparison:
| Evergreen Endodontics | Typical General Office | |
|---|---|---|
| Training | Two to three years of residency beyond dental school, spent entirely on endodontic diagnosis and treatment | A general degree; root canals are one competency among many |
| Volume | 10,000+ root canals completed — the full schedule, every day of the week | A few cases a month, fitted around the rest of general practice |
| Magnification | Surgical microscope, up to 14x, on every procedure — calcified and hidden canals get located | Loupes or unaided vision; difficult anatomy can be missed |
| Sedation | Nitrous, oral, or IV sedation available for every appointment | Varies widely; IV sedation is uncommon outside specialty offices |
Your Visit
The Appointment, From Check-In to Relief
An hour, give or take — and most of it is surprisingly uneventful, which is exactly the point.
Examine & Image
Digital X-rays and a focused exam come first; complex roots get a 3D CBCT scan. Everything is reviewed with you, together.
Explain & Approve
Diagnosis, options, and exact cost in plain language. You give the green light before any treatment happens.
Relieve & Restore
Deep numbing, careful microscope work, and your choice of sedation. Most island patients are back on I-90 within the hour.
Comfort Menu
Sedation, Three Ways
Nervous patients are this specialty's bread and butter. Pick your level of awareness:
| Option | How It Feels | Best For |
|---|---|---|
| Nitrous Oxide | Feather-light relaxation that evaporates within minutes — safe to drive yourself home | Mild anxiety, straightforward cases |
| Oral Sedation | A pill before your appointment; profoundly relaxed, with the details pleasantly blurred | Moderate fear, longer procedures |
| IV Sedation | The deepest conscious sedation we offer, adjusted in real time by Dr. Dejbod | Severe anxiety, surgical or retreatment cases |
The Instrument Room
Serious Instruments for a Serious Job
A root canal succeeds or fails at the microscopic level. This operatory is built around that fact:
Surgical Microscope
Magnification up to 14x brings hidden canals, tiny fractures, and complex anatomy into full view.
3D CBCT Imaging
Reveals the complete root system before treatment — no surprises mid-procedure.
Digital X-Rays
Instant, low-radiation imaging, walked through with you on a chairside monitor.
Apex Locator
Electronic measurement confirms each canal is cleaned to its precise endpoint.

Cost & Insurance
The Numbers, Before Anything Else
In-network PPO rates are fixed by your insurer — the same at every in-network office. What differs is the skill and technology behind the fee. Insured patients typically pay $160–$655 out of pocket when benefits remain.
| Root Canal | Typical In-Network Rate | Without Insurance |
|---|---|---|
| Front tooth (anterior) | ~$800 in-network contracted rate | from ~$1,300 without insurance |
| Premolar (bicuspid) | ~$1,000 in-network contracted rate | from ~$1,500 without insurance |
| Molar | ~$1,300 in-network contracted rate | from ~$1,900 without insurance |

Getting Here
From Mercer Island: 15–20 Minutes on I-90
Take I-90 east — against traffic in both directions for most of the day — to exit 17, and you're at 600 NW Gilman Blvd. Compare that with the alternative: fighting into downtown Seattle, paying a garage, riding an elevator, and doing it all with a throbbing tooth. Eastgate and Factoria commuters already know the corridor; the island is one easy exit further.

Questions
Mercer Island Root Canal FAQs
Practical answers for island patients.
Why leave Mercer Island for a root canal?
Because specialist-level endodontics isn't on the island — and the trip east is easier than the trip west. We are 15 to 20 minutes away on I-90 at exit 17, with free parking at the door and no downtown Seattle garage or elevator between you and the chair.
Is the drive against traffic?
Most of the day, yes. Morning rush flows west toward Seattle while you head east, and the evening pattern reverses in your favor too. Mercer Island patients routinely make the trip in under 20 minutes.
Do you offer same-day appointments for island residents?
Yes — same-day slots are reserved every business day for severe pain, swelling, and cracked teeth. Call early and you can usually be treated the same day; the short I-90 drive makes same-day care genuinely practical from the island.
What does a root canal cost with insurance?
Contracted PPO rates work out to roughly $800 for an anterior tooth, $1,000 for a premolar, and $1,300 for a molar. Insured patients with remaining benefits generally pay $160–$655 out of pocket — verified before treatment, approved by you.
Can I be sedated for the whole procedure?
Effectively, yes. IV sedation puts you in a deep twilight state with little or no memory of the appointment, and it is adjusted continuously by Dr. Dejbod. Nitrous and oral options are available for lighter anxiety.
