The new Crest 3D White Teeth Whitening Pen is a brush-on whitening gel in an easy-to-use pen. The pen has soft bristles that help you apply the whitening gel exactly where you want it. With regular use, the Crest 3D White Teeth Whitening Pen helps erase surface stains. It also uses the same whitening ingredient dentists use.
Use Crest 3D White Professional Whitestrips + Light if you want to achieve professional-level whitening. Use Crest Daily Whitening Serum for noticeable whitening. Use Crest 3D White Teeth Whitening Pen between whitening treatments and for easy whitening on-the-go.
DIRECTIONS: Remove the cap and twist the bottom of the pen clockwise until gel dispenses through the brush (it may take several turns the first time). Twist the bottom of the pen 1 full turn so triangle symbols align and a small drop is dispensed. Smile and brush a thin layer of gel onto each tooth avoiding the gums. Replace cap. Wait 60 seconds before closing mouth. Avoid eating or drinking for 1 hour after application. Apply 2 times per day for at least 14 days.
We recommend using the pen twice a day at least 1 hour before eating or drinking.
The whitening gel inside the Crest 3D White Teeth Whitening Pen contains peroxide, the same teeth whitening ingredient dentists use. It also has a mint flavor for freshness.
The triangle symbols are there to help you know when you’ve dispensed the right amount for a single application. Line up the symbols, turn the bottom of the pen so the symbols line up again, and apply the amount of gel dispensed to teeth.
We recommend applying a thin layer up to 2 times a day; to help whiten your teeth, avoid closing your mouth after application for the full 60 seconds.
