    Best dentist in town. I’m terrified of going to the dentist but the atmosphere and the staff are amazing. There’s no upselling like I’ve had at other locations… they go above and beyond to help you in any way possible.

    So friendly and helpful. Colleen’s kind words and soothing voice sure helps. Dr. Irwin is also kind and generous! Very professional.

    I was a patient with Dr. Bruce and was concerned about the changes that were happening. But, I am very happy with Drs Irwin and Trzcinski. The office is a pleasure to visit as it is so bright and clean and the staff is amazing.

No more goopy impressions

A quick digital scan instead of the tray

For crowns, bridges, veneers and nightguards, we take your impressions with a Primescan, a small wand that photographs your teeth in 3D.

No trays of impression paste, no gagging, and you can watch your scan come together on the screen. It’s one of the ways we’ve made a visit here more comfortable.
