"Bent" star Amanda Peet shares her secrets for achieving & maintaining a red-carpet-worthy smile:

Smile Bright
A bright, white smile is a necessity in my line of work, so I make sure to keep mine in tip top shape by using the Crest 3D White 2 Hour Express Whitestrips, which are fast, effective and easy!

Seeing Red
On set, when it is important to call attention to my mouth, the makeup artist will often choose a red or dark lip color with a blue undertone, allowing my teeth to look even whiter.

Picture-Perfect
A little lip gloss goes a long way! I make it a point to sneak some on before photos on the red carpet to make sure I look polished in every shot.

Enhance Your Best Assets
Pick a feature and stick with it. If you go with a bold lip color to enhance your smile, then tone down your eye makeup. If you go with the eyes, then go nude with your lips. No matter which you choose, a brilliant white smile goes with both!

Tricks of the Trade
A makeup artist once shared this tip with me: when attempting to keep your smile white, try drinking soda or coffee with a straw to avoid direct contact with the teeth.
