Editor's Pick: Food always gets stuck between teeth where your toothbrush can't reach, and a quick rinse with this flosser clears it right out. The 300ml tank holds enough water for a full mouth cleaning without needing a refill. A single charge lasts up to a month, and it's compact enough to toss in your bag for travel. New users can start with the soft mode to let gums adjust for a few days, then increase the pressure once you're used to it.
