My close friend used to face some embarrassing moments whenever she goes for the parties, as most of the people would make fun of her yellow teeth. She tried almost every product to come out of this, but all in vain. As per the physician’s advice, she makes her mind to use crest whitestrips supreme, which is a product that can be used by placing a plastic strip directly onto to the teeth. Initially she had some irritation in gums and even white spots on the teeth but vanished after sometime. She felt some changes after 2 days and a few days later, she started getting compliments from all those who made fun earlier. The crest supreme professional whitestrips found to be more effective for yellow teeth. As far as price is concerned, it is comparably lesser than physician the fee for whitening the teeth. The only problem is it will be sensitive to cold and hot water for two days initially. Since the active ingredient in it is hydrogen peroxide, it is not recommended for children under 12. I feel it is the best among all teeth whitening products.
