We set our teeth on edge, lie through our teeth and sink our teeth into innumerable edible treats that render our chompers varying shades of white, or worse. Give teeth a clean streak with today's WagJags from Light Smiles Express:

• $11 for an advanced teeth whitening pen (a $39.95 value)
  
• $19 for a home teeth whitening kit (a $99 value)
  

While crayons boast beautiful shades of snow, ivory or seashell white, it is not crayons but pens that can help teeth achieve that alluring shade of white. This teeth whitening pen makes it easy to touch up your smile, whether you're on the go or running through your morning makeup routine. Simply brush the gel onto your teeth using the pen's dispenser, maintain a one-minute smile and voila - your white teeth will give you a reason to grin for several more minutes. Each pen contains 14 to 20 treatments and the potential to make teeth two to six shades whiter.

Get the whole shebang with option two, sending a home teeth whitening kit to your door. Brighten teeth with a teeth whitening pen, plus two thermal mouth trays, one finger brush and a shade guide. Simply apply the pen, place the tray in your mouth for half an hour, and then remove to reveal your whiter, brighter smile.
