Whitening Toothpastes
All toothpastes help remove surface stains because they have mild abrasives. Some whitening toothpastes contain gentle polishing or chemical agents that provide additional stain removal effectiveness. Whitening toothpastes can help remove surface stains only and do not contain bleach; over-the-counter and professional whitening products contain hydrogen peroxide (a bleaching substance) that helps remove stains on the tooth surface as well as stains deep in the tooth. Whitening toothpastes can lighten your tooth's color by about one shade.
Over-the-Counter Whitening Strips and Gels
Whitening gels and Whitening Strips are clear, peroxide-based gels applied with a small brush or thin strips are applied directly to the surface of your teeth. Instructions generally call for twice a day application for 14 days. Initial results are seen in a few days and final results are sustained for about 4 months.
Tray-Based Teeth Whitening Products
Tray based tooth whitening systems, purchased either over-the-counter or from your dentist, involve filling a mouth guard-like tray with a gel whitening solution – which contains a peroxide-bleaching agent which usually contains a higher concentration of Chemical Agents. Wearing the tray for a period of time, generally from a couple hours a day, everyday for up to 4 weeks and even longer (depending on the degree of staining and desired level of whitening). Bocelli Musical Teeth Whitening tray shortens that time in half by using 30 minutes a day for 7 to 14 days depending on your desired result.
