AMAZING staff!! I’ve never had surgery before so they reassured me a lot about the procedure and asked a couple of times if I had any questions. They really care about your comfort and safety. Super quick and painless and I was home within 2 hours. I can’t say enough good things!

About as painless a dental experience that someone could expect! One observation - would be nice if the printed care instructions were in synch with the oral instructions. Was given some great verbal notes, but wasn’t on the after care handout.
