"The Blue Boa is as essential to my job as my loupes & headlight. I use it on every patient, every day. Its easy to use, easy to disinfect and it works just like it should. It makes my job so much easier and cuts the time Im using the ultrasonic in half. There is no need to have patients hold a suction or to clean one tooth and then have them close around a suction...the blue boa is truly a game changer. The best part is that patients dont feel like they are choking on water anymore! When I changed jobs and brought mine into my new office the other hygienists thought I was crazy, but then they saw me use it and were sold. Our dentist bought one for all of his hygienists. If you are using an ultrasonic and you have not tried this high powered suction, you are doing yourself and your patients a disservice."
