Teeth Whitening


Many teeth whitening systems are available, including whitening toothpastes, over-the-counter gels, rinses, strips, and trays, and whitening agents obtained from a dentist.

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.

Whitening Systems

Whitening Toothpastes

All toothpastes help remove surface stains because they contain 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 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 our office can make your teeth three to eight shades lighter.

Over-the-Counter Whitening Strips and Gels

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 four months.

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 four months.

Whitening Rinses

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. 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 (i.e. just two minutes a day compared to 30 minutes for many strips) so it may have less of an effect.

Tray-Based Tooth Whiteners

Tray-based tooth whitening systems, purchased either over-the-counter or from our office, 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 Whitening

Bleaching your teeth in our office provides the quickest way to whiten teeth. The whitening product is applied directly to the teeth. These products are used in combination with heat, a special light, and/or a laser. Results can be seen in only one, 30- to 60-minute treatment. But to achieve dramatic results, several appointments are usually needed. However, in some cases, dramatic results can be seen after the first treatment.

How Long Do Teeth Whitening Effects Last?

Teeth whitening is not permanent. People who expose their teeth to foods and beverages that cause staining may see the whiteness start to fade in as little as one month. Those who avoid foods and beverages that stain may be able to wait one year or longer before another whitening reatment or touch-up is needed.

The degree of whiteness will vary from individual to individual depending on the condition of the teeth, nature of the stain, the type of bleaching system used, and for how long.

What are the differences between whitening your teeth at home and having them bleached in our office?

Who Should Not Undergo Teeth Whitening?

Whitening is not recommended or will be less successful in the following circumstances:

Risks Associated With Teeth Whitening

The two side effects that occur most often with teeth whitening are a temporary increase in tooth sensitivity and mild irritation of the soft tissues of the mouth, particularly the gums. Tooth sensitivity often occurs during early stages of the bleaching treatment. Tissue irritation most commonly results from an ill-fitting mouthpiece tray rather than the tooth-bleaching agent. Both of these conditions usually are temporary and disappear within one to three days of stopping or completing treatment.

If you do experience sensitivity, you can reduce or eliminate it by:
