A healthy smile is able to win people over by displaying rows of pearly white teeth and emitting a cartoon "ding" sound whenever it shows itself. Teach teeth to audibly twinkle with today's Groupon: for $69, you get a Diamond Elite ultrasonic toothbrush, plus a UV sanitizing charger base, three replacement brush heads, and free shipping from Bling Dental (a $228.95 value).
Raymond Frye, DMD, develops convenient at-home pearl-polishing devices to forge dentist-chair results.The Elite ultrasonic toothbrush invigorates morning routines by scrubbing teeth at the speed of 30,000 dynamic strokes per minute. A built-in alert sounds every 30 seconds, letting brushers know to switch areas and reward themselves with a piece of saltwater taffy, before a two-minute timer signals the end of cleaning. The toothbrush's plaque remover reaches where normal bristles can't, and an ergonomic design cultivates brushing comfort. Personalize each dental baptism with the adjustable modes of whitening, gentle, and massage, and at brushing's end, send the Elite home to its UV sanitizing charger base to shoo away any bacterium who mistakenly thought the UV light was a disco ball.
