Truly the best dentist experience I’ve ever had! I feel like many people get a bit of anxiety going to the dentist, but this has opened my eyes to how amazing it can be! Kendra was AMAZING. She was so informative and thorough. She explained exactly what was going on with my teeth in such a simple way and steered me in the right direction. Dr. Dreher is incredible as well.

“Dr. Dreher and his staff safely removed my amalgam filling. They answered everyone of my questions and listened to me about my concerns regarding waiting longer to feel number before beginning the procedure and checking in with me often to make sure I was ok. It was a really positive experience and I’m so relieved my mouth is now amalgam free. Thanks Dr. Dreher!”

“My son made me an appointment after listening to me complain about a tooth too long! Dr. Dreher is a new dentist for us, and he got me in right away for a very over sensitive tooth. His application of Novocain was above and beyond. I didn't feel it even a bit the way he pre numbed me with a topical.”
