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. As an endodontist, I specialize in the intricate inner workings of your teeth - the nerves, blood vessels, and tissues that keep them alive. 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.

A 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

State-of-the-Art Technology
Advanced equipment and techniques for precise, comfortable, and efficient endodontic care. Our technology reduces treatment time, improves outcomes, and enhances your comfort.
Surgical Microscope
Dr. Nima uses a microscope during treatment for enhanced vision through illumination and up to 14x magnification. This greatly improves precision, especially in locating calcified canals and diagnosing root fractures.
- Up to 14x magnification precision
- Enhanced illumination
- Better treatment outcomes
3D CBCT Imaging
Three-dimensional Cone Beam Computed Tomography provides detailed information that traditional x-rays cannot. This advanced imaging helps us examine teeth, roots, and surrounding bone in three dimensions.
- 3D visualization
- Precise treatment planning
- Detect hidden problems
Digital X-Rays
Digital radiography uses electronic sensors to capture and store images on computer. Images can be viewed instantly and enlarged for better diagnosis, while reducing radiation exposure by 80-90%.
- 80-90% less radiation
- Instant results
- Enhanced image quality
Digital Instrumentation
Our advanced digital handpieces control high-tech nickel-titanium instruments with precision. These systems sense resistance levels and adjust automatically, reducing treatment time and improving comfort.
- Automated precision
- Reduced treatment time
- Enhanced comfort
Apex Locator
This device precisely measures root length electronically for complete cleaning. Its accuracy reduces the number of x-rays needed during procedures, further lowering radiation exposure.

Ultrasonic Technology
Advanced ultrasonic devices vibrate diamond-coated tips at high frequency to supplement traditional instruments. This technology enables precise material removal and enhanced disinfection under the microscope.
- Precise material removal
- Enhanced disinfection
- Improved bacteria elimination
Our Technology Promise
Microscope Magnification

How 3D Imaging Saved the Day
Dr. Nima shares a real patient story of how our advanced 3D imaging technology identified the problem when other dentists couldn't, saving the patient's tooth.
Why Microscopes Matter
Dr. Nima explains why he would never have a root canal done on his own tooth without a microscope. Root canals performed with microscopes have much higher success rates.
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.
Your Choice, Your Approval
If you need treatment, we'll go over all options and costs upfront. Nothing is done until you review everything and give us your approval to move forward.
Don't Wait - Tooth Pain Gets Worse
The sooner you get treatment, the easier it is to save your tooth. We see emergencies the same day or next day - not next week like other practices.
