DryShield is working very well for patients age 9 and up for sealants and permanent tooth restorations. It helps free up my assistant so she can do more for the patients during procedures. It also is huge during general anesthesia cases and saves time for me while retracting the lips and tongue. The pedo size mouthpiece works well for teens and young adults too. I am probably saving about 25% of my time using this device. Autoclaving is simple and easy.
