Whitening

How Can I Brighten My Smile?

Submitted By Andersan Bloomer, DDS

 

Your wedding is coming up, and you want your smile to be its brightest. Or maybe you have an important speaking engagement. Whatever the reason, tooth bleaching isn't just for movie stars, and it isn't just for one day. Many people have had their teeth bleached, and probably millions more are thinking about it. The desire for a brighter smile with whiter teeth is very strong, and tooth bleaching safely lightens the color of the teeth, lasting for up to five years. The most effective and safest method of tooth bleaching is dentist-supervised.

Generally, bleaching is successful in at least 90% 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. Gray stains caused by fluorosis, smoking or tetracycline use can be lightened, but results are not as dramatic. If you have very sensitive teeth, periodontal (gum) disease or teeth with worn enamel, your dentist may discourage bleaching.

What's Involved?

First, the dentist 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 lightened immediately. Your dentist may use an in-office bleaching system while you sit in the dental chair. Some patients choose dentist-supervised at-home bleaching, which is more economical and provides similar results.

 If you choose at-home bleaching, at your next appointment your dentist or hygienist will make impressions of your teeth to create a mouthguard appliance. 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 it. Along with the mouthguard, you'll receive the bleaching materials. You'll be given instructions on how to wear the mouthguard.

 Some bleaching systems recommend bleaching your teeth for several hours a day. Generally this type of system requires two to four weeks to complete. Other systems recommend bleaching at night while you sleep. This type of system usually requires only 10-14 days to complete.

How It Works and Safety

Lightness should last from 1-5 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. The retreatment time is much shorter than the original treatment time.

The active ingredient in most of whitening agents is carbamide peroxide; when water comes into contact with this white crystal, the release of hydrogen peroxide lightens the teeth.
