The perfect smile is marked by pearly white teeth and the ability to say "cheese" without opening your mouth. Help improve the first part of this equation with today's Groupon: for $75, you get a professional at-home teeth-whitening kit and maintenance whitening pen from Whitening Lightning (a $478 value).
Whitening Lightning's at-home kit and whitening pen slough off stains to reveal comely chompers. The dial a smile kit leaves teeth four to seven shades whiter per treatment, and the Super Booster pen polishes pearlies whiter with two weeks of regular use. Designed to be painless and easy to use, the whitening kit employs gel and an LED light to unsully incisors in about 20 minutes. Each kit contains three treatments and one papier-mâché dentist. Tooth tidiers can use the treatments every three to six months, or as little as a week apart, to dispatch stubborn stains from smoking cigarettes and drinking wine, coffee, and finger paint.
The Whitening Lightning Super Booster pen garbs teeth in a whitening agent that dries in a minute and works overnight. Though powerful enough to dissolve headstrong stains, the whitening pen is designed to leave no sensitivity, foul taste, or damage to tooth enamel. In addition to granting a sparkling-white smile, the whitening pen helps freshen breath and makes teeth strong enough to bite through diamonds. And though many teeth-whitening products contain carbamide peroxide, which can lead to tooth sensitivity, Whitening Lightning uses fast-acting hydrogen peroxide, which gently coddles teeth into a spotless state.
