Solar Powered and Made in Japan High Tech Ionic Toothbrush - Works with any type of light sourcenClinically Proven: More effective than other toothbrushesnReduces the risk of Periodontal Disease and Bleeding GumsnPrevents new plaque and biofilm from forming via the ionic actionnToothpaste is not needed or recommendednThe Soladey-3 uses electrically transmitted ions to facilitate the removal of plaque and aid in teeth cleaning. The electronic reaction makes the bonds between the plaque and the tooth weak which allows the plaque to be removed easily. The very low level current cannot be felt and is completely safe.nThe Soladey-3 is from Japan and is fast becoming one of the most popular toothbrushes on the market.nnINCLUDED: 1 SOLEDAY-3 TOOTH BRUSH u0026 1 PACK OF REPLACEMENT BRUSH HEADS (PLEASE CHOOSE COLOR BELOW)nnHOW IT WORKS:nThe electronic reaction is produced via a Solar Panel (1) in the toothbrush's base that transmits the electrons to a (2) titanium oxide semiconductor located just below the brush head. There, the electrons are carried from the semiconductor (3) through water (u0026 saliva) to the teeth. A circuit is created from the mouth back to the brush via the stainless steel handle. The reaction makes the bonds between the plaque and the tooth weak which allows the plaque to be(4) removed easily. The very low level current cannot be felt and is completely safe.nItem is Brand new and sealed!nAs an extra we have included a 4 pack of replacement brushes (Medium).
