Living with Tooth Pain or Infection Shouldn't Be Your Normal
A toothache that comes and goes, sharp pain when you bite down, or sudden sensitivity to hot and cold can be easy to explain away at first. If you leave them untreated, the infection inside the tooth usually gets worse. Swelling can spread toward the gum and jaw, and pain that started as an occasional twinge can turn constant.
That’s why at Kirkland Dental Excellence, we offer treatments for root canal in Kirkland to stop the infection where it starts, so you can save the tooth and get out of pain, often in a single visit.

What a Root Canal Treats
A root canal therapy removes infected or inflamed tissue from inside a tooth, cleans out the space, and seals it so the infection can’t come back.
This treatment is typically recommended for:
- A deep cavity that has reached the tooth's nerve
- A cracked or chipped tooth exposing the inner pulp
- Repeated dental work on the same tooth
- Tooth pain that worsens with pressure or temperature
- Swelling or tenderness in your gum near a specific tooth

⭐️⭐️⭐️⭐️⭐️ I had a fantastic experience at my dental cleaning today! From the moment I walked in, the front desk staff were welcoming, helpful, and made check-in a breeze. The office itself is clean, comfortable, and has a calming atmosphere that immediately put me at ease. The hygienist and dentist had such great bedside manner—friendly, professional, and genuinely caring. They explained everything clearly and made sure I was comfortable throughout the entire visit. It’s rare to find a team that combines excellent care with such outstanding customer service. I left feeling well cared for and grateful to have found a dental office that treats patients like family. Highly recommend!Posted on Google![]()

I’ve been going there for several years. It has been a great experience. They are very careful in the work they do—much better than other dentists I have gone to in the past. I strongly recommend them.Posted on Google![]()

Dr. Davis has been my dentist for years, ever since he took over the practice from Dr. Fong, and I think I've interacted with just about everyone in the office, and they are all INCREDIBLE. Seriously, these are some of the kindest, most professional, totally on the ball people you will ever have the pleasure of visiting for a dental appointment. I'm sad to be leaving the state, because it means I will no longer be able to go to Eastview Family Dental, which is a tragedy. They really are the best!Posted on Google![]()

What to Expect from Your Root Canal Process
Exam & Diagnosis
Dr. Hedayati examines the tooth and takes a digital X-ray to confirm the infection and check the surrounding bone.
Numbing & Access
We numb the area fully, then we make an opening in your tooth to reach the infected pulp inside.
Cleaning & Sealing
Dr. Hedayati removes the infected tissue, cleans and disinfects the canal, then fills and seals to keep the infection from returning.
Restoring the Tooth
Most root canals are finished with a crown, which protects the tooth and lets you bite and chew normally again.
Does Insurance Cover Root Canal Treatment?
Dental insurance typically covers a meaningful portion of root canal cost, since it’s considered a necessary procedure rather than an elective one, though coverage varies by plan and by tooth. At Kirkland Dental Excellence, we review your benefits with you and explain what’s covered before treatment begins. Call us at (425) 827-2003 to check your coverage and discuss financing options.

Root Canal vs. Tooth Extraction
| Root Canal | Tooth Extraction | |
|---|---|---|
| Your natural tooth | Stays in place | Removed |
| Bite & chewing | Functions like your other teeth | Needs a replacement (implant, bridge, or denture) to restore function |
| Jawbone health | Preserves the bone that supports the tooth | Can lead to bone loss over time without a replacement |
| Recovery | Mild soreness for a few days | Healing time varies, often followed by a second procedure |
| Cost over time | One procedure plus a crown | Extraction plus the cost of a replacement tooth later |
| Long-term outlook | Often lasts many years, and sometimes a lifetime, with good care | Effective, but adds a second treatment to restore the smile |
