How does it work?

(teeth + plaque + saliva)

Both tooth and plaque are negatively charged by nature.
It is saliva with its positively charged Ca ions that binds the two together stubbornly.

the power of ionization

IONIC KISS™ ionic toothbrush generates a negative ion field that attracts the binding agent away.
As a result the bond is weakened, tooth surface and plaque now repel each other making removal of plaque easier.
