In the last 3 months I have had all of my teeth cleaned, 2 fillings replaced and (my first crown) 1 crown completed. Dr. Gagnon's dental expertise was excellent and the service from ALL of her staff was outstanding. My teethe look better than they have in years. Additionally, within the last week my husband had a cleaning and 1 filling done, also a great experience! We are both very pleased.

She makes me super comfortable although I have anxiety about going to the dentist.

I hadn't been in for a cleaning in a long time, due to personal circumstances, and I was welcomed here without judgement. Everyone was so kind and welcoming, and I learned more about how to take better care of my teeth! Highly recommend them for any dental needs :)
