While quickest way to whiten teeth is with white spray paint, it often leaves the face with a ghostly pallor that scares away fully alive dates. Retain your shade with today's Groupon for the next speediest method at Quik Smiles, valid at five participating locations. Quik Smiles lightens dogged discolourations on insipid incisors in a welcoming, relaxed environment. Today's Groupon is good for two back-to-back ten-minute treatments of self-administered teeth whitening. This easy process combined gel-filled mouth trays with a blue LED light to speed up whitening and provide mood lighting for the subsequent rave. Lustrous whites can remain three to eight shades brighter than before the treatment for up to one year with at-home touch-ups using a choice of a Quik Smiles Whitening Pen or Wite-Out (neither included).
