While bleaching is safe, it requires a dentist's supervision to ensure proper results. Not only may an over-the-counter product not work well enough, but it might work too well. There is a wide range in results when using these products without supervision. If a bleaching agent is too strong, or used for too long, teeth can wind up with an unnatural, frosty look.

Is bleaching for you?

Generally, bleaching is successful in at least 90 percent of patients, though it may not be an option for everyone. Consider tooth bleaching if your teeth are darkened from age, coffee, tea or smoking. Teeth darkened with the color of yellow, brown or orange respond better to bleaching. Other types of gray stains caused by fluorosis, smoking or tetracycline are lightened, but results are not as dramatic. If you have very sensitive teeth, periodontal disease, or teeth with worn enamel, bleaching is not recommended until your problems are fixed.

What's involved?

First, Dr. Tran will determine whether you are a candidate for tooth bleaching and what type of bleaching system would provide the best results.

If you're in a hurry for whiter teeth, you may decide to have your teeth bleached immediately. Our office offers the latest and the world number one in-office laser whitening system called Zoom 2. With this system, you experience minimal post-bleaching sensitivity and you can have your teeth lighten up to eight shades in just 45 minutes.

If you don't choose laser bleaching, our office also offer traditional take-home tray bleaching. In this case, an impression of your teeth will be made to fabricate a mouthguard appliance for you. The mouthguard is custom made for your mouth and is lightweight so that it can be worn comfortably while you are awake or sleeping. The mouthguard is so thin that you should even be able to talk and work while wearing your mouthguard. Along with the mouthguard, you'll receive the bleaching materials. You'll be given instructions on how to wear the mouthguard. You can have the result in 14 days.

How long does it last?

Bleaching should last from one to five years, depending on your personal habits such as smoking and drinking coffee and tea. At this point you may choose to get a touch up.

Is it safe? Any side effects?

A number of studies, during the past five years, have proven bleaching to be safe and effective. Some patients may experience slight gum irritation or tooth sensitivity, which will resolve when the treatment ends.

What are realistic expectations?

No one can really predict how much lighter your teeth will become after bleaching. Every case is different. Typically, there is a two-shade improvement as seen on a dentist's shade guide. The success rate depends upon the type of stain involved and your compliance. Bleaching can only provide a shift in color from gray to a lighter shade of gray, for example. Bleaching does not lighten artificial materials such as resins, silicants, or porcelains.
