A regular toothbrush uses just friction to dislodge plaque around your teeth, but not the Kiss You Ionic toothbrush ($18.90). It releases negative ions that make the tooth surface repel plaque, so it’s easier to remove. With more effective brushing, you’ll have cleaner, whiter teeth and healthier gums. Turn on the ionic action by touching the metal pad on the toothbrush handle. The built-in battery can last up to one year with normal use. Available at Sasa, Changi General Hospital, Metro, Robinsons, OG and Nishino Pharmacy.
