A healthy environment
All instruments and surfaces are sterilized and disinfected according to ADA and CDC guidelines. However, there's another potential problem in dental offices for which there is no legal requirement for compliance. That is the quality of the water used to cool high-speed instruments and to rinse your mouth.
You probably don't know that the small-diameter tubing within dental units when not specially treated develops something called a "biofilm". A biofilm is a sticky mass full of bacteria, very much like the plaque that forms on your teeth. Each of our dental units contains an independent water supply bottle for two purposes. First, it allows us to use a known clean water supply. Second, it allows us to treat the waterlines.
We periodically test the quality of our treatment water by collecting samples and culturing them. In that way, you (and we) can be assured that you are not breathing or swallowing contaminated mist or water.
