My new love! Crest 3D white strips for super pearly white teeth! My boyfriend has the yellowest teeth ever, I let him try two strips in two days, and it is now a light yellow! lol. You use it for a week, but you see results in just 3 days. The taste and smell is unpleasant, but the Price of $21 and quality makes up for the negatives. I have been using Crest white strips for 3 years. Never had a problem with them. If you have sensitive gums, ask your dentist if you can use it. Otherwise, use only once or twice a year. The whiteness lasts for 6 months.
