Effectiveness The Vitis Waxed Tape has a flat wire. This ensures optimal cleaning of the spaces between the teeth. If an interdental brush or a stoker does not fit in between, floss thread is the solution. Vitis Tape removes dental plaque and easily gets under the gum line, even with very small interdental spaces. The tape is waxed, making it easy to apply between the teeth. The tape contains fluoride and mint.
