DentaBurst freshening teeth cleaners are the next best thing to keeping a toothbrush and toothpaste with you at all times, but much more convenient. Slip the minty little sleeve over your forefinger and rub it over your teeth and gums — you don’t need water — and in second your teeth feel plaque-free and your breath is fresh. Just in time for that last-minute meeting.
