Brushing and flossing are everyday ways to keep your teeth bright, white, and healthy. Still, if you might feel like your smile is lacking some sparkle or is more yellow than it used to be, you’re not alone. When the American Academy of Cosmetic Dentistry asked people what they’d most like to improve about their smile, the most common response was whiter teeth. The American Association of Orthodontists also found that nearly 90% of patients requested tooth whitening.

Why Did My Teeth Change Color?
Over time, your teeth can go from white to not-so-bright for a number of reasons: Food and Drink, Tobacco Use, Age, Trauma, and Medications.

How Does Teeth Whitening Work?
Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.

What Are My Whitening Options?
Talk to your dentist before starting. If you are a candidate, there are four ways to put the shine back in your smile:

Stain Removal Toothpastes
All toothpastes help remove surface stain through the action of mild abrasives that scrub the teeth. Look for whitening toothpastes that have earned the ADA Seal of Acceptance for stain removal (it will tell you on the package). These toothpastes have additional polishing agents that are safe for your teeth and provide stain removal effectiveness. Unlike bleaches, these types of ADA-Accepted products do not change the color of teeth because they can only remove stains on the surface.

At-Home Bleaching from Your Dentist
Your dentist can provide you with a custom-made tray for at-home whitening. In this case, the dentist will give you instructions on how to place the bleaching solution in the tray and for what length of time. This may be a preferred option if you feel more comfortable whitening in your own home at a slower pace, but still with the guidance of a dentist. Out-of-office bleaching can take anywhere from a few days to a few weeks.

Over-the-Counter Bleaching Products
You may see different options online or in your local grocery store, such as toothpastes or strips that whiten by bleaching your teeth. The concentration of the bleaching agent in these products is lower than what your dentist would use in the office. If you are thinking about using an over-the-counter bleaching kit, discuss options with your dentist and look for one with the ADA Seal of Acceptance. That means it has been tested to be safe and effective for teeth whitening. Get a list of all ADA-Accepted at-home bleaching products.
