Microbrush Dri-Aids is an alternative to cotton rolls. Unlike cotton rolls, they adhere to the tissue which prevents them from becoming dislodged. Microbrush Dri-Aids not only block saliva, but they also protect the tongue and cheeks from being cut by the dental drill. They are ideal while prepping teeth, placing dental sealants, bonding a composite restoration, seating crowns, and applying fluoride. They come in both large and small sizes. Two types of Dri-Aids are manufactured by Microbrush International. They are available with or without a silver laminated coating. The coating, which is located on one side, helps to reflect light which improves visibility during dental procedures.
