I had a really pleasant experience here. The dental hygienist, receptionist and dentist are all very friendly and nice. The dental hygienist was very informative and let me know exactly what she was doing, when she was doing it and why she was doing it and that really helped with my anxiety. I love this place and I 100% recommend them. Thank you Healthy Smile!

Quick Service

I chipped a tooth and was able to get in right away. They provided a temporary that stayed intact and after a few weeks I was able to come back to get my crown. The crown fits perfectly and looks better than my original tooth. Very sweet dentists, very quick service, and very reasonable prices for what was done. Thank you Healthy Smile!
