With over-the-counter tooth bleaching products now readily available, at-home tooth whitening is increasing in popularity. Tooth bleaching products contain peroxide, which lightens the natural color of the teeth and removes surface stains. When used as directed, at-home bleaching products can leave you with noticeably whiter teeth.
Methods
You can choose over-the-counter gels, strips or whitening trays to bleach your teeth at home, or your dentist can provide you with a custom-fitted mouth tray and a stronger whitener that you can use at home. The products are applied to the teeth daily or nightly for a specified amount of time--often for two to four weeks, depending on the method used.
Considerations
Tooth bleaching is not helpful for some people with discolored teeth. According to the American Dental Association, yellow stains typically bleach out well, but stains that are brown in color may be more difficult to eliminate. If your teeth have a gray tint, bleaching products may not improve the appearance of your teeth. If you have had bonding or have tooth-colored fillings, keep in mind that these areas will not bleach and they may become more noticeable after you bleach your teeth.
Costs
Over-the-counter bleaching products range in price from less than $20 to over $100, depending on the product. According to the Cleveland Clinic, at-home bleaching product systems dispensed by a dentist may cost $300 to $600.
Risks
The most common risks associated with home tooth bleaching are tooth sensitivity and gum irritation, according to the University of Maryland Medical Center. You are less likely to experience gum irritation if you choose a dentist-dispensed whitening product. Your dentist will make a tray that fits your teeth perfectly so less of the product ends up on your gums where it can cause irritation, according to the Cleveland Clinic.
Alternatives
Daily use of whitening toothpaste can help remove surface stains and improve the appearance of the teeth. While toothpastes are an inexpensive whitening option, they do not actually change the color of the teeth like bleaching products, according to the ADA. In-office bleaching procedures offer the quickest, most dramatic results, but they are also more expensive than at-home methods.
Warning
Always use home tooth bleaching products according to the package directions or your dentist's instructions. If you develop irritation or discomfort while using a bleaching product, see your dentist for advice. If you have gum or mouth disease, very sensitive teeth or worn tooth enamel, talk to your dentist before using a whitening product.
