Denti-Styx Flexible Inter-dental Sticks (Approx 100) Denti-Styx are so flexible that they can bend without breaking &, as they are not made from wood, they cannot splinter or break. The ability to bend at right angles means that Denti-Styx can reach the most awkward places in your mouth. As the inside gums are higher in the mouth than the outside, the unique ski-shaped profile of Denti-Styx helps prevent unnecessary injury to your gums by sliding over inside gums rather than damaging them. The tip of each Denti-Styx is so fine that it can safely clean even in the smallest spaces. The tip can also be shaped into a tiny hook, which is ideal for cleaning under the contact point where the teeth meet. Denti-Styx have a flexible concave base that automatically adjusts to the different size spaces between your teeth, Ideal for those who find flossing difficult.
