Hydro Floss Parts Vs Getting A New HydroFloss
HydroFloss parts are important if you want to save the cost of purchasing a new one. However the cost of ownership is very low. If your HydroFloss only lasts 3 years (most last longer than that) you have paid less than $3 per month for the cost of ownership.
Therefore, the cost for purchasing a brand new HydroFloss is very, very low. If you believe that the HydroFloss can help you keep your teeth for a lifetime of good service, as I do, then it is a no brainer.
