About Eastern Iowa Endodontics
Root canals here often wrap up in under 30 minutes, and patients regularly drive hours to see Dr. Derek T. Peek for that speed and gentleness.
Eastern Iowa Endodontics is a general dental practice that also offers traditional braces and TMJ treatment, though most reviews focus on endodontic visits with Dr. Derek T. Peek. Reviewers repeatedly note how quickly root canals are finished, often in a single 20-to-30-minute visit rather than the multiple appointments some patients had elsewhere. Several patients say they traveled from well outside Cedar Rapids, some several hours away, because of the care they received. Comfort measures like the GentleWave system and letting patients signal for more numbing come up often alongside detailed, step-by-step explanations of each procedure.

He very good n his team is awesome. He is so fast to get it all done. Not to mention the sunglasses he gives his clients for sitting in the chair to get it done r pretty cool to.
Dr. Peet and staff were awesome! Nice facility, friendly and professional people. My root canal experience went smoothly and painlessly (aside from the unavoidable little pinch of the Novocain shots, haha!) I would definitely recommend.
I drove about 2 in a half hours from home and I won’t lie I was DREADING this appointment for months!!! I’ve never had a root canal and i’ve heard so many horror stories.. I talked to the ladies in the front about how I was a little nervous and all the things and they reassured me that Dr Peek does a lot of root canals and he’s such a nice man! I waited only a little bit in the waiting room which is very very nice by the way, I got called back got numb and got er done! I kid you not I was in and out of the chair in less then 25 minutes! Dr and his nurse made me feel so at home, comfortable and welcome!! I seriously appreciate my nurse calming some of my anxiety by having conversations with me pre operation! If I or anyone EVER needs work done like this I will be referring them here!! The drive was so worth it! Thanks so much again for everything!!! You guys are seriously ROCK STARS!!! HIGHLY RECOMMEND! :)
Can't say enough about this entire experience. Starting with Carmen at the front desk. She was pleasant and scheduled me accordingly. She then called me back about 45 mins later and said there was a cancelation and I could be seen the next day! I had a 2 hour drive and I made it in about 15 mins after my set time. When I arrived I was greeted professionally. Kendra then took x-rays, explained the root canal procedure and then Dr. Peek entered. Very vibrant and down to earth. He introduced himself and the student that was shadowing him for that day. He numbed me, and then numbed me again (per my request). Dr. Peek and Kendra make a great team. I wasnt bothered at all during the entire procedure. They were smooth in their communication with each other and me during the procedure. Alot of medical professionals have lost their bedside manner but not this establishment. They were worth the drive and procedure. I highly recommend. Thank you Kendra, Carmen and Dr. Peek, keep keeping up your good work! Hope to not have to see you again anytime soon but ill send folks your way who need to!!
Dr. Peek and his staff assisting with the root canal were amazing! He was so friendly, calmed my nerves, and made quick and efficient work of my root canal! He was honest and extremely proficient at his job. Would recommend Dr. Peek to everyone:) Thank you!
