This is NOT my first time purchasing this product. Colgate Optic Overnight Teeth Whitening Gel Pen is MY go to when I am looking for quick, easy, and effective teeth whitening. I have tried others. None work as well as this. I am HIGHLY SATISFIED with this product and will buy it over and over again. Thanks, Colgate, and thanks WALMART for making this product available at such a TERRIFIC PRICE and for promptly delivering it to my home SAVING me BOTH TIME and MONEY!

Whiter Teeth Overnight!

After one treatment my teeth were whiter. After several treatments my whole mouth was whiter and brighter than they had been in years! I highly recommend Colgate Optic White. Love the product!

this product works great, I drink a lot of tea and it takes the stains off, but by morning my mouth feels really nasty from the product caking on my teeth.
