What is an Endodontist?

While all endodontists are dentists, less than three percent of dentists are endodontists. Just like a doctor in any other field, endodontists are specialists because they’ve completed an additional two or more years of training beyond dental school. Their additional training focuses on diagnosing tooth pain and performing root canal treatment and other procedures relating to the interior of the tooth.

Great experience. Very professional and friendly. State of the art equipment which makes time in the chair go a lot quicker and easier. Got an appointment within a few days. Doctor and staff communicated everything well and made sure I was comfortable throughout the procedure. Environment, setting and decor were very pleasant. I highly recommend using Cascade Endodontics.

I am a dentist. I have had many dental experiences with many different great dental professionals...everything from crowns to implants to bone and gum grafts......too many hostess cupcakes as a kid! Dr. Welk just did a root canal for me today......hands down the best dental experience I've ever had! The office is spotlessly clean. The staff is skilled and helpful. And, Dr. Welk is calm, gentle and obviously highly skilled. We are very fortunate to have him as part of the Portland health care community.

Dr Welk is an excellent Endodontist! I’ve had no pain with any of my root canals. His chair side manner and thorough communication is so good. He has seen almost any issue you can imagine in his 20 years of practice so he is great at resolving tough problems. I’d recommend him in a heartbeat.
