Teeth whitening is ideal for people who have healthy, unrestored teeth (no fillings) and gums. Individuals with yellow tones to their teeth respond best. But this cosmetic procedure is not recommended for everyone.

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 carbamide peroxide or hydrogen peroxide (a bleaching substance) that helps lighten the color deep in the tooth.
Whitening toothpastes can lighten your tooth’s color by about one shade. In contrast, light-activated whitening conducted in your dentist’s office can make your teeth three to eight shades lighter.
Whitening gels are clear, peroxide-based gels applied with a small brush 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. The retail cost for this product is about $15 for a 14-day treatment.
Whitening strips are very thin, virtually invisible strips that are coated with a peroxide-based whitening gel. The strips are applied twice daily for 30 minutes for 14 days. Initial results are seen in a few days and final results are sustained for about 4 months. The retail cost for this product ranges from $10 to $55 for a 14-day treatment.
Among the newest whitening products available are whitening rinses. Like most mouthwashes, they freshen breath and help reduce dental plaque and gum disease. But these products also include ingredients, such as hydrogen peroxide, which whiten teeth. Manufacturers say it may take 12 weeks to see results.
Whitening rinses are fairly inexpensive: a 30-day supply will probably cost less than $10. They may also be simpler to use than some other whitening products. You just swish them around in your mouth for 60 seconds twice a day before brushing your teeth.
However, some experts say that rinses may not be as effective as other over-the-counter whitening products. Because a whitening rinse is only in contact with the teeth for such a short time – just two minutes a day compared to 30 minutes for many strips — it may have less of an effect.
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 – and wearing the tray for a period of time, generally from a couple hours a day to every day during the night for up to four weeks and even longer (depending on the degree of discoloration and desired level of whitening).
In-office bleaching provides the quickest way to whiten teeth. With in-office bleaching, the whitening product is applied directly to the teeth. These products can be used in combination with heat, a special light, and/or a laser. Results are seen in only one, 30- to 60-minute treatment. But to achieve dramatic results, several appointments are usually needed. However, with in-office bleaching, dramatic results can be seen after the first treatment.
In-office bleaching procedures range in cost from $200 to $500 per arch, or $500 to $1,000 for the whole mouth.
