Procter & Gamble Compliment - Crest Night Effects Whitening Gel
TUPPERS PLAINS, OHIO -- I use Crest Night Effects Whitening Gel at least once a year. I drink 2 cups of coffee per day and get these disgusting brown lines on the edges of my teeth. Used as per the directions, the results are great! I have NO complaints about the effectiveness of this products.
There is only 1 flaw that I can see. 1. I can't find it in the store anymore.
