For decades, professional teeth whitening had been exclusive to dental offices, often with a high price tag and multiple appointments. However, Crest White Strips has changed the landscape of professional whitening by making teeth whitening accessible for all consumers as an affordable and convenient product. The strips are thin, flexible pieces of plastic coated on one side with a peroxide-based gel. Simply align the strips with your teeth and the strips will adhere and maintain a snug fit while they begin to remove surface stains on your teeth to create a whiter smile over time. Below is a thorough overview of how they work, what to expect, and how to ensure you see the best results.
