Read the announcementA Personal Message from Dr. Nima
"Look, I get it - nobody wants to be here. Most people don't wake up excited about dental work, and honestly? I don't blame you. But here's the thing: you're in pain, you're worried about losing your tooth, and you just want someone who actually understands what you're going through. That's exactly why I became an endodontist. Every day, I get to help people who are scared, anxious, or just plain fed up with tooth pain - and I get to give them their life back. When I see that relief on someone's face after we save their tooth and eliminate their pain, that's what makes this work meaningful to me. You're not just another appointment - you're someone who deserves to feel better, and I'm here to make that happen."- Dr. Nima Dejbod, DMD
YOUR ISSAQUAH ENDODONTIST
We are in the practice of saving teeth!
What is Endodontics? When your tooth is in severe pain or infected, you're facing a crossroads: lose the tooth forever, or save it. That's where I come in.

I'll give you the honest truth about your tooth's condition, explain all your options clearly, and help you understand the risks and benefits of each choice. My goal isn't just to perform a procedure - it's to help you make the best decision for your unique situation, whether that's a painless root canal to save your natural tooth, or guiding you toward the right alternative. You deserve to know exactly what's happening and have a partner who respects your choices every step of the way.

Have Questions About Your Treatment?
Dr. Nima takes time to explain every aspect of your treatment. No question is too small, and we want you to feel completely informed and comfortable.
Do I Need a Root Canal?
A root canal treats an infected or damaged tooth, helping to stop pain and save your natural tooth. If you have any of these signs, even if they come and go, it's time to get it checked.
Tooth Pain That Comes and Goes
If one tooth keeps bothering you, even off and on, it could mean there's a problem inside. Pain when chewing or lying down is a common warning sign.
Sensitivity to Hot or Cold
When hot coffee or cold ice cream causes sharp pain that lingers long after you're done, your tooth's nerve may be damaged and need treatment.
Tooth Discoloration
A tooth that's turning dark or gray often means the nerve inside is dying. This can happen even without pain, so don't ignore color changes.
Swelling in Gums or Face
Swelling around a tooth, tender gums, or facial swelling can indicate an infection that needs immediate attention to prevent it from spreading.
Persistent Bad Taste or Smell
A constant bad taste in your mouth or bad breath that won't go away, especially near one tooth, can indicate infection or abscess.
Pain That Wakes You Up
Throbbing pain that keeps you awake at night or wakes you from sleep is often a sign of serious infection that needs emergency treatment.
What Happens During Your Visit?
Gentle Examination
Dr. Nima will carefully examine your tooth and may take 2D and 3D imaging to see what's happening inside.
Clear Explanation
We'll explain exactly what we found and discuss all your treatment options in language you can understand.

Frequently Asked Questions
Answers from Dr. Nima Dejbod, DMD — Vice President, Washington State Association of Endodontists.
What are the signs I need emergency root canal treatment?
Seek immediate emergency endodontic care if you experience: severe tooth pain that keeps you awake, throbbing tooth pain, swollen gums with tooth pain, tooth sensitivity to hot and cold that lingers, or signs of tooth abscess. These infected tooth symptoms require urgent dental care.
I have severe tooth pain - can I get same day treatment?
Yes! We provide emergency root canal treatment and same day endodontist appointments for patients experiencing severe tooth pain. Call us immediately at (425) 697-9777 for urgent dental care. We serve patients throughout the greater Seattle area including: Issaquah, Sammamish, Bellevue, Redmond, Newcastle, Renton, Mercer Island, Kirkland, Bothell, Woodinville, Preston, Carnation, Fall City, North Bend, Snoqualmie, Hobart, Covington, Roslyn, Cle Elum, Maple Valley, Black Diamond, Tukwila, Kent, SeaTac, and Seattle. Same-day emergency appointments are available for urgent cases.
How quickly can you provide tooth pain relief?
We prioritize emergency cases and can often provide same day tooth pain relief. Our emergency root canal procedures in Issaquah are designed to eliminate severe tooth pain immediately. Call for urgent appointment scheduling.
Do you offer weekend or after hours emergency appointments?
While our regular office hours are Monday-Friday, we can arrange after hours emergency appointments for severe tooth pain and urgent cases. There is an additional after-hours office fee of $200 for weekend or after-hours emergency visits. Contact us immediately for emergency tooth pain relief.
What happens if I delay emergency root canal treatment?
Delaying emergency root canal treatment can lead to serious consequences: The infection will continue to spread, causing more bone loss in your jaw. You may experience increased swelling, severe pain, and difficulty sleeping. The tooth becomes harder to numb for future treatment, making procedures more challenging. The prognosis becomes poorer over time, and you may ultimately lose the tooth entirely. What starts as a treatable emergency can progress to a life-threatening infection requiring hospitalization. Seek immediate emergency endodontic care to prevent these complications.

Why am I having tooth discomfort and pain?
Tooth discomfort and pain typically occur when bacteria invade the inner pulp of your tooth, causing inflammation and infection. This can happen due to deep decay, repeated dental procedures, large fillings, cracks, or trauma. When bacteria reach the pulp (the soft tissue inside your tooth containing nerves and blood vessels), your body's immune system responds with inflammation, which creates pressure inside the tooth and causes pain. If left untreated, the infection can spread to the surrounding bone and tissues, leading to abscesses and more serious complications.
What happens if pain goes away, does that mean it's ok?
No! When tooth pain suddenly goes away, it often means the situation has actually gotten worse, not better. Think of sensitivity to hot and cold as your tooth's 'check engine light' - it's an early warning system. When this sensitivity disappears, it usually means the nerve inside your tooth has died and the tooth is now infected. A dead, infected tooth won't hurt initially, but the infection will continue to spread to the surrounding bone and tissues. If not treated promptly, this can lead to serious complications including bone loss, abscess formation, facial swelling, and ultimately tooth loss. Don't ignore the temporary relief - seek endodontic evaluation immediately.
Why does the X-ray show bone loss around the tip of the roots?
Bone loss around the tip of tooth roots occurs when bacteria and toxins from an infected or dead nerve leak out through the root tip into the surrounding bone. Your body's immune system responds to this infection by breaking down and removing the infected bone tissue, creating a dark area (radiolucency) visible on X-rays. This bone loss, called a periapical lesion or abscess, will continue to grow if the infection source is not eliminated. Root canal treatment removes the infected nerve tissue and seals the root canals, allowing your body to heal and regenerate the lost bone over time. Without treatment, the bone loss will continue to expand and may affect neighboring teeth.
Why is my tooth discolored?
Tooth discoloration after root canal treatment occurs for several reasons: Nerve Death: When the nerve inside your tooth dies (from trauma, decay, or infection), it can cause the tooth to darken from the inside out, similar to how a bruise changes color. Blood Breakdown: Dead blood vessels and tissue inside the tooth break down and release pigments that stain the tooth structure. Medications: Some medications used during root canal treatment can cause temporary discoloration. Age and Trauma: Previous trauma to the tooth, even years ago, can cause gradual darkening over time. Good News: Tooth discoloration after root canal treatment can often be corrected with internal bleaching (whitening from inside the tooth) or external whitening treatments. We offer professional internal bleaching services to restore your tooth's natural color and improve your smile's appearance.
Why do I have to take X-rays again if I took them at my dentist?
Even if you had X-rays taken at your dentist yesterday, we need our own 2D X-rays for several important reasons: Different Angles: Think of it like taking photos of a car accident - the police, insurance adjuster, and mechanic each need their own photos from different angles to see what they need to see. Your dentist takes X-rays to check for cavities and general health, but we need specific angles to see the root canals and surrounding bone. Specialized Views: It's like the difference between a family photo and a passport photo - both are pictures of you, but they serve different purposes. We need periapical X-rays that show the entire root and surrounding bone, not just the crown of the tooth. Treatment Planning: Just like a surgeon needs their own MRI or CT scan before surgery (even if you had one elsewhere), we need our own images to plan your specific treatment safely and effectively. Quality Control: We need to ensure the images are the right quality and angles for endodontic diagnosis - sometimes images from other offices aren't optimal for our specialized needs.
Why is 3D CBCT imaging important for my treatment?
3D CBCT imaging is like the difference between a regular photograph and a 3D hologram - it shows us everything we can't see with regular 2D X-rays. Complete Picture: Think of 2D X-rays like looking at a house from the street - you can see the front, but you can't see what's behind it, inside it, or on the other sides. 3D imaging is like having X-ray vision to see through all the walls, rooms, and hidden spaces. Hidden Anatomy: Just like a GPS needs 3D mapping to navigate complex highway interchanges, we need 3D imaging to navigate complex root canal systems. Some teeth have extra canals, curved roots, or unusual anatomy that's completely invisible on 2D X-rays. Safety First: It's like the difference between performing surgery with a flashlight versus full surgical lighting - 3D imaging ensures we can see everything clearly and avoid complications. Treatment Success: Think of it like a surgeon needing an MRI or CT scan before a complex procedure - the 3D information is essential for the highest success rates and safest treatment. While insurance may not always cover 3D imaging, it's often necessary for your safety and the best possible outcome.
Why am I having discomfort after a filling or crown with my dentist?
Discomfort after a filling or crown can occur for several reasons: The procedure may have irritated the nerve inside your tooth, especially if the decay was deep or close to the pulp. Sometimes the bite needs adjustment if the restoration is slightly high. However, if you experience persistent pain, sensitivity to hot/cold, or throbbing pain that keeps you awake, this may indicate that the nerve has been damaged and requires root canal treatment. If discomfort persists beyond a few days or worsens over time, contact us at (425) 697-9777 for an endodontic evaluation to determine if root canal treatment is needed.
Should I put a crown on a tooth if it's having symptoms without a root canal?
No, you should not place a crown on a symptomatic tooth without addressing the underlying problem first. If your tooth is experiencing pain, sensitivity, or other symptoms, it likely indicates nerve damage or infection that requires root canal treatment. Placing a crown over an infected or inflamed nerve will not solve the problem and may actually make it worse by sealing in the infection. The proper sequence is: 1) Root canal treatment to remove the infected/inflamed nerve, 2) Allow healing time, then 3) Place the crown. This ensures long-term success and prevents future complications.
What is the treatment for cracked teeth (cracked tooth syndrome)?
Treatment for cracked teeth depends on the severity and symptoms. For cracks without symptoms, a crown may be sufficient to protect the tooth and prevent the crack from spreading. However, if you have symptoms like pain when biting, sensitivity to hot/cold, or spontaneous pain, this indicates the nerve inside the tooth has been affected and root canal treatment is needed first, followed by a crown. The sequence matters: if you place a crown on a symptomatic cracked tooth without addressing the nerve problem, symptoms will persist and we would need to drill through your new crown to perform the root canal - an unfortunate and costly situation. Another option is extraction, which is a 100% guarantee to eliminate the problem, but then you have a missing tooth and need to consider replacement options like dental implants, bridges, or partial dentures, which can be significantly more costly than saving your natural tooth. That's why we always evaluate cracked teeth thoroughly with 3D imaging to determine the best treatment approach and whether the tooth can be successfully saved.
Will Anbesol help my tooth pain?
Anbesol (benzocaine) is a topical numbing agent that may provide very temporary relief by numbing the surface of your gums and tooth, but it will not address the underlying infection or inflammation causing your pain. It's only a temporary band-aid solution. For true tooth pain relief, you need professional endodontic treatment to remove the infected or inflamed nerve tissue. While over-the-counter pain medications like ibuprofen can help manage discomfort until you can see an endodontist, topical numbing agents like Anbesol are not effective for deep tooth pain and should not delay seeking proper treatment.
Will antibiotics cure an infected tooth?
No, antibiotics alone cannot cure an infected tooth. While antibiotics can help control the spread of infection and reduce swelling temporarily, they cannot reach the source of the infection inside the tooth's root canal system. The infected or dead nerve tissue must be physically removed through root canal treatment. Think of it this way: if you had a splinter in your finger that was infected, antibiotics might help with the surrounding infection, but you'd still need to remove the splinter. Similarly, the infected nerve tissue is like that splinter - it must be removed for complete healing. Antibiotics are often prescribed as an adjunct to root canal treatment, but they are not a substitute for it.
Why should I see an endodontist (endodontic dental specialist) for a root canal?
Endodontists are dental specialists who focus exclusively on root canal treatment and have completed 2-3 additional years of specialized training beyond dental school. Here's why this matters: We perform root canals every day (Dr. Nima has completed over 10,000 procedures), while general dentists may only do a few per month. We use advanced technology like surgical microscopes and 3D imaging for more precise treatment. We have specialized instruments and techniques for complex cases. We can handle difficult anatomy and challenging situations that general dentists may refer out. Our success rates are typically higher due to our specialized training and experience. We focus solely on saving teeth, making us experts in endodontic diagnosis and treatment.
How long do root canals last?
Root canals can last many years, often decades, but they don't automatically last a lifetime. Think of it like putting a new tire on your car - you've fixed the problem and the tire can last for years, but you can't control if you hit a nail on the road down the line. Research shows: Root canals have success rates of 85-97% over 8-10 years when properly done and maintained. What affects longevity: The age and quality of your crown is just as important, if not more important, than the root canal itself. An old, leaking crown can let bacteria back into the tooth, contaminating the root canal. Other factors include: tooth cracks or fractures that develop over time, your oral hygiene and gum health, grinding or clenching habits, and the tooth's location and function. Maximizing lifespan: Get a high-quality crown promptly after root canal treatment, maintain excellent oral hygiene, see your dentist regularly for checkups, and protect your teeth from trauma. The bottom line: While we can't guarantee a lifetime, proper treatment and care give your tooth the best chance for long-term success.
Are all root canals the same so should I shop around?
No, all root canals are not the same, and quality varies significantly between providers. Key differences include: Technology used (surgical microscopes vs. naked eye, 3D imaging vs. 2D X-rays), Experience level (specialists vs. general dentists), Time dedicated (we spend 60-90 minutes vs. rushed 30-minute appointments), Technique and materials (latest rotary instruments vs. hand files), Success rates (specialists typically have higher success rates), Comfort measures (various sedation options vs. just local anesthesia). While cost is a consideration, root canal treatment is an investment in saving your natural tooth. A failed root canal often requires retreatment or extraction, which costs more in the long run. Choose based on expertise, technology, and success rates rather than just price.
What are typical root canal costs with insurance?
With insurance, you get discounted rates and then insurance pays most of it: Front teeth: $800 discounted rate (normally $1300). With 80% coverage, you pay about $160. Middle teeth: $1000 discounted rate (normally $1500). With 80% coverage, you pay about $200. Back teeth: $1300 discounted rate (normally $1900). With 80% coverage, you pay about $260. Remember: These are estimates. Your actual cost depends on your specific insurance coverage percentage and remaining annual benefits.
How does dental insurance help me save money?
Insurance saves you money in two big ways: 1. Discounted Rates: We accept much lower rates from insurance companies. Example: A root canal costs $1900 without insurance, but only $1300 with insurance - you save $600 just by having insurance! 2. Insurance Pays Part: Then your insurance covers 50-80% of that $1300. If they cover 80%, they pay $1040 and you only pay $260. Your Total Savings: You pay $260 instead of $1900 - that's $1640 in savings! Plus, cleanings and exams are usually free with insurance.

What is my annual benefits allowance and how does it work?
Your annual benefits allowance is the maximum dollar amount your insurance will pay toward your dental care each calendar year, typically $1000-2000 (some plans offer up to $3000+). Simple Example: You have $1500 in annual benefits. You get a $1300 root canal. Your insurance covers 80%, so they pay $1040. This uses up $1040 of your $1500 annual allowance, leaving you with $460 remaining for the year. Key Points: Benefits reset every January 1st. Unused benefits expire December 31st - they don't roll over. We help you track your remaining benefits and plan treatments to maximize your coverage.
Why do I lose my dental benefits if I don't use them?
Dental insurance operates on a 'use it or lose it' basis - unused benefits expire on December 31st and do NOT carry over to the next year. This is different from health savings accounts or vacation time that might roll over. Why This Happens: Insurance companies budget for a certain amount of claims each year. Unused benefits become profit for the insurance company, not savings for you. The Reality: You've already paid for these benefits through your premiums (or your employer has). Not using them means you're essentially giving money back to the insurance company. Smart Strategy: Plan your dental care to maximize your benefits each year. If you need treatment, it's often better to complete it before benefits expire rather than wait until next year when you'll have to 'start over' with your deductible and annual maximum.
