Brush & Bond MAX's Touch Application technique eliminates the need to scrub the prep, providing consistent, even, and complete coverage of the entire prep surface. Simply dip the chemically treated Brush&Bond Activator Brush into 1 to 3 drops of liquid and touch it to the prep surface until the entire prep is wet. This easy application process helps ensure MAXimum adhesion between the tooth and the restorative, while virtually eliminating post-op sensitivity.
