Hydrofloss provides a combination of water pressure & pulsation that disrupts biofilm, stimulates gums and cleans between teeth and below the gumline. Hydrofloss is the only irrigator to combine the proven effectiveness of oral irrigation with the science of magnetohydrodynamics. Oral irrigation with magnets provides 64% greater reduction in tartar (calculus) As water flows through the magnetic field in the handle, the water molecules are saturated and temporarily become neutrally charged.
