Plaque is bonded to teeth by positive ions that are contained in saliva. Negative ions released from Sparkle Ionic Toothbrush loosen this bonding mechanism between the teeth and plaque, making it easy to remove plaque without harsh brushing

How to attach a brush head: Snap a new brush head into place over the metal band.
How to remove a brush head: Twist gently while holding brush head. Replace the brush head every 3 months.
How to activate the negative ions: With a wet finger, lightly touch the metal band. Hold the handle while keeping your palm or finger on the metal band as you gently brush your teeth with  back-and-forth and up-and-down motions.
How to check the battery life of the integrated battery: Push the battery tester button.  If red light appears, the battery is still working. The battery lasts 1 year with normal use. Replace with a new Sparkle Ionic Toothbrush  once fully consumed.
