The risks of teeth whitening

Are you considering whitening your teeth? Before you do, discuss the possible risks with your dentist — especially if you plan to whiten (bleach) your teeth using an at-home bleaching system.

Risks associated with teeth whitening include tooth sensitivity and damage to the roots of teeth. Dentists may be able to predict if you will have problems with or sensitivities to the procedure. They also may be able to help you alleviate sensitivity and recommend toothpastes designed to treat sensitive teeth. Dentists can also monitor patients for signs of root damage and treat the condition if detected in time.

Teeth coloration

Why do teeth “change color?” The internal portion of teeth normally darken over time, and personal habits — such as tobacco use or drinking coffee, tea and other beverages — can cause staining externally. Certain medications also can discolor teeth.

Bleaching is used to alter the color of the teeth. Teeth cleaning by your dental office, however, can often remove external stains — and promotes good oral health.

Generally, bleaching is successful in at least 90 percent of patients. As a rule of thumb, yellow-colored teeth respond to bleach well, while brownish-colored teeth respond less well. Gray stains caused by smoking, tetracycline or fluorosis (ingestion of too much fluoride) most likely will not be dramatically changed by bleaching.

Likewise, bleaching may not enhance your smile if you have had bonding or tooth-colored fillings placed in your front teeth. The whitener will not affect the color of these materials, and they will stand out in your newly whitened smile. In these cases, you may want to investigate other options, such as porcelain veneers or dental bonding.

To bleach or not?

Is bleaching a good option for you? Here are some questions to ask:

What does your dentist advise? Not all stains can be lightened by over-the-counter or professional bleaching, and your dentist will be able to give you guidance. If you have very sensitive teeth, gum disease or teeth with worn enamel, your dentist may discourage bleaching.

Is bleaching worth the cost? Bleaching and teeth whitening procedures in the dental office are not typically covered under Delta Dental plans. Always check your specific plan coverage before undergoing any dental procedure or treatment.

Whether or not you decide to whiten your teeth, keep in mind that a good daily oral health regimen and regular checkups go far in keeping your smile bright and healthy.
