How does Opalescence™ teeth whitening work?
Teeth whitening is the removal of stains and discolorations from the enamel and dentin. The outer layer of the tooth is enamel, and beneath the enamel is dentin. Enamel is thin and typically much lighter in color, while dentin is darker in color and makes up the bulk of the tooth. Enamel can be discolored over time simply from age, but also from outside sources like coffee, tea, tobacco, and other foods and beverages. Also, as we age, our enamel thins, causing more dentin to show through, making the overall appearance of the tooth look darker.
Opalescence whitening gels contain a powerful whitening ingredient—either carbamide peroxide or hydrogen peroxide. Peroxide gels break down into water, oxygen, and reactive oxygen molecules. These reactive oxygen molecules oxidize the bonds of discolored stain molecules. By changing the stained molecules, the tooth appearance becomes lighter.1

Do I need to refrigerate Opalescence™ teeth whitening products?
During shipping, refrigeration is not required. Once received, some Opalescence™ teeth whitening products require refrigeration, and others do not.
Keep Opalescence Go™ teeth whitening trays and Opalescence™ PF 35% and 45% syringes stored in a refrigerated environment between 36°F (2°C) and 46°F (8°C).
Opalescence™ PF 10%, 15%, and 20% syringes should be stored between 36°F (2°C) and 81°F (27°C), which means that these products may be stored refrigerated or at room temperature.
If a portion of a syringe is unused following a treatment, replace the cap on the syringe and store it appropriately to be used for the next teeth whitening treatment.

Why should I whiten my teeth?
People whiten their teeth for many reasons. You can bring back some of that youthful appearance with a whiter, brighter smile. Do you have a wedding or important day coming up? A whiter smile can help brighten up special occasions. Some people whiten their teeth before a job interview to get that extra boost of confidence that comes with making a great first impression.
According to a recent survey by the American Academy of Cosmetic Dentistry, “close to one in two (48%) people believe that a smile is the most memorable feature after first meeting someone—more so than the first thing a person says (25%).” That same survey also found that “more than a third of respondents view people with a flawed smile to be less attractive (37%) and less confident (25%) than those with perfect teeth.” Smiles make a lasting impression and a bright, white, beautiful smile won’t be forgotten.

Is teeth whitening for everyone?
Teeth whitening is a safe, comfortable way to get a bright, white smile. Results and treatment time may vary depending on the level of staining and whiteness desired. Crowns, bridges, fillings, and veneers will not whiten. Those with gum disease, worn enamel, cavities, and exposed roots may not be good candidates for whitening their teeth. We recommend visiting your dentist for a pre-whitening consultation so that they can help you choose the professional option that best fits your needs.

Should I use teeth whitening if I am pregnant, breastfeeding, or undergoing fertility treatment?
Like with many other dental or medical treatments, people have wondered if teeth whitening during pregnancy, breastfeeding, or IVF is safe.
Because no studies have been done regarding the safety of teeth whitening during pregnancy, the ADA suggests that "clinicians may consider recommending that teeth whitening be deferred during pregnancy."2 Most dental professionals follow this suggestion, making it the standard protocol throughout the dental community, and recommend their patients don't whiten during pregnancy or fertility treatments.
We agree and recommend that pregnant or breastfeeding women, women undergoing fertility treatment, and patients with serious health concerns do not use teeth whiteners.

Will teeth whitening give me sensitive teeth?
Tooth sensitivity is a relatively common side effect of teeth whitening. However, Opalescence whitening has not been shown to weaken tooth enamel.3,4 If sensitivity occurs, it is most often temporary and will go away when you've completed the whitening process. If you do experience tooth sensitivity, there are ways to treat it using desensitizing toothpastes and gels such as Opalescence™ Whitening Toothpaste Sensitivity Relief or UltraEZ™ desensitizing gel. Consult with your dentist to determine the best treatment for your needs.

Do teeth whitening lights work?
Lots of other in-office whitening treatments use an LED light or a laser during the whitening process. You've probably seen commercials for these kinds of teeth whiteners. Or maybe you've even seen kiosks in the mall where they use a light to whiten your teeth. Are these lights and lasers really effective, though?
Current research shows that only hydrogen peroxide (the whitening agent used in Opalescence™ Boost in-office whitening and Opalescence Go™ tray whitening) or carbamide peroxide (the whitening agent used in Opalescence™ PF custom-tray whitening) are effective in whitening teeth. No LED teeth whitening lights are necessary with Opalescence teeth whitening, as lights do not affect the whitening results.5 In fact, some research shows that using a light for whitening can be harmful to lips and gums.6
-
Are activated charcoal teeth whitening products effective?
There is no evidence that brushing your teeth with activated charcoal is better, safer, or more effective than standard whitening toothpaste. Charcoal leaves a mess, tends to settle at your gumline, and is difficult for a dental hygienist to remove. Although the abrasiveness of the charcoal may help remove some surface stains, you may risk abrading your enamel too much. Such damage may not be repaired. Additionally, it is impossible for charcoal to actually change the color of your tooth. The only substance proven to whiten the color of your enamel is activated oxygen, such as that released by the peroxide contained in Opalescence™ teeth whitening.
If you are looking for a whitening toothpaste, we recommend Opalescence™ Whitening Toothpaste which successfully whitens by removing surface stains and is gentle enough to use daily without damaging your enamel.

Can I use Opalescence™ teeth whitening products with crowns, veneers, fillings, or other dental work?
Yes, it is safe to use Opalescence™ whitening products on any unnatural tooth surface. If your natural teeth begin to yellow or develop stain, your goal may be to whiten those teeth so that they more closely match your existing dental work. Whitening treatments will not affect the color or shade of a crown, veneer, implant, filling, or tooth restoration.
We recommend abstaining from any whitening treatments for 7–10 days before a bonding procedure.7-9

How fast can I whiten my teeth?
Everyone responds differently to whitening treatments and everyone will whiten at different rates. Some stains are easier to treat than others. Teeth that are yellow or brown are easier to whiten than teeth that are gray-ish. Younger patients typically whiten more quickly than older patients, but every patient is different.
When whitening, keep in mind that your smile looks most natural when the color of your teeth matches the whites of your eyes. Some people want a Hollywood white smile, but that is not a natural color for teeth and few people can actually reach that color of white. Compare strengths and wear times for our various Opalescence™ whitening products and consult with your dentist to help determine the right option for you.

How much does teeth whitening cost?
The cost of teeth whitening can vary greatly depending on what you use and where you get it. While over-the-counter teeth whiteners are the least expensive, they may not be the most effective because they are not tailored to your specific needs and they may increase the risk of having sensitive teeth. Other dentist-administered teeth whitening treatments may be more expensive because of costly teeth whitening lights or lasers used in the procedure, but these accessories generally do not provide any added benefit. Opalescence™ teeth whitening offers the benefits of a dentist prescribed whitening treatment without any costly gimmicks, making it the best value. Talk to your dentist about specific costs and to determine the best whitening option for you.

How long do teeth whitening results last?
Teeth whitening results are very stable, leaving you with a stunning smile long after your teeth whitening treatment is over. However, there are a few factors that can make teeth lose their luster. Things like genetics, diet, age, some medications (like tetracycline), and certain habits (like smoking) may affect the length of your whitening results. Fortunately, touch-up treatments are quick and easy, helping you get that bright, white smile back.
