I never had to doubt their qualifications. They made their credentials completely obvious, which made me feel a lot safer. They took the time to explain in detail plenty of techniques I could practice at home to prevent cavities and tooth decay. I loved that they let me rinse my mouth every few minutes during my procedure. It's always uncomfortable trying to sit through an entire procedure without being able to rinse or relax your jaw for a minute. I was in awe at the level of service I received. They completely surpassed all my expectations and I will absolutely be going back. It was nice of them to offer some sample toothbrushes and toothpaste for me to take home. I was able to figure out which toothpaste I liked without having to buy anything.
