This ultra suave toothbrush is designed for immediate care of sensitive and/or diseased tissue. This is the “Elite” version with pearlized handles. The cover protects and compresses approximately 11,070 ultra soft .003 diameter DuPont Tynex bristles. The 41 tuft adult is availabe in four color coded, bristle lengths, the Red (.437) is the longest, Orange (.397) a little shorter, Yellow (.357) shorter yet, and Blue (.317) is the shortest length. The brushes feel softer or more firm with the length of the bristle. Red feels softest and Blue feels more firm… but all are ultra soft.
