Question 2 of 20 Correct

Why does everyone eventually experience yellow teeth over time?

Correct! Sorry, that’s incorrect.

The correct answer is: As you grow older the enamel on your teeth slowly becomes thinner. The underlying layer called dentin not only yellows, but with aging it begins to show through more because the enamel is thinner.

Question 4 of 20 Correct

What percentage of the U.S. Population is dissatisfied with the color of their teeth?

Correct! Sorry, that’s incorrect.

The correct answer is: One-third of people in the United States report they are dissatisfied with their tooth color. The good news is that with the growth of more whitening options, the availability to do something about the shade of your teeth is becoming much more accessible.

Question 5 of 20 Correct

How old should you be before whitening your teeth?

Correct! Sorry, that’s incorrect.

The correct answer is: Before whitening your teeth, make sure your adult teeth are fully developed. Adult tooth development usually happens by the age of 14. Before the pulp in your teeth has fully had time to develop, your teeth will be too sensitive for whitening treatments. It is best to consult your dentist before trying any whitening treatments.

Question 6 of 20 Correct

Which of the following does not cause tooth discoloration?

Correct! Sorry, that’s incorrect.

The correct answer is: Tobacco is a clear link in causing tooth enamel to turn yellow over time. With gum disease, your tooth enamel is endangered. Gum disease causes your teeth to lack necessary protection against stains and yellowing. Also many antibiotics prescribed to treat other diseases have a history of causing yellow teeth discoloration. Among the most popular drugs that discolor teeth are tetracycline and doxycycline, as well as drugs for high blood pressure. Head/neck radiation and chemotherapy have been linked to discolored teeth as well.

Question 7 of 20 Correct

How can toothpaste whiten your teeth?

Correct! Sorry, that’s incorrect.

The correct answer is: Whitening toothpaste is one of the milder forms of teeth whitening. While it cannot remove the internal stains it can help to remove surface stains on your teeth.

Smile Bright
Question 8 of 20 Correct

What do intrinsic stains refer to?

Correct! Sorry, that’s incorrect.

The correct answer is: Intrinsic stains refer to the internal natural coloration of your teeth. These stains can be whitened by both at home and in-office bleaching methods. Whitening methods such as whitening toothpaste will only treat extrinsic stains (surface stains) not the internal intrinsic stains.

Question 9 of 20 Correct

What is the active ingredient in bleaching treatments?

Correct! Sorry, that’s incorrect.

The correct answer is: The peroxide found in whitening treatments can be one of two kinds, either hydrogen peroxide or carbamide peroxide. The amounts of peroxide found in treatments will vary depending on treatment type, with in-office procedures containing much higher peroxide levels.

Question 10 of 20 Correct

How soon could you need a touch up of your tooth whitening treatment?

Correct! Sorry, that’s incorrect.

The correct answer is: On average your new tooth shade will last from six months to three years, depending on what you eat. Non-smokers and people who avoid stain-causing foods and beverages will experience much longer results of their whitening procedure. Also regular cleaning and good oral care along with regular checkups can prolong the time needed between whitening treatments.

Smile Bright
Question 11 of 20 Correct

Which of the following is not true in regards to how OTC and in-office whitening treatments differ?

Correct! Sorry, that’s incorrect.

The correct answer is: While some may believe that they can achieve equal whitening results at home; that is not the truth. Over the counter (OTC) treatments not only contain lower levels of peroxide; they cannot target the specific areas that your dentist can. Another convenience of in-office whitening is the amount of time you can save by having a dental health professional do the treatment for you.

Smile Bright
Question 12 of 20 Correct

What is the average price for an in-office teeth whitening treatment?

Correct! Sorry, that’s incorrect.

The correct answer is: There are many whitening options available, with a wide range of prices. Whitening toothpastes are the mildest form and usually only whiten teeth one shade. Whitening toothpastes cost about three dollars. Over-the-counter (OTC) whitening treatments range anywhere from 20 to 40 dollars, while a take-home treatment can cost you up to 500 dollars. A professional in-office whitening treatment can cost up to 1,000 dollars.

Smile Bright
Question 13 of 20 Correct

How much whiter will in-office bleaching leave your teeth?

Correct! Sorry, that’s incorrect.

The correct answer is: Different whitening treatments provide different results. With over-the-counter (OTC) strips, you can generally lighten your teeth by six shades. However, strips won't cover all parts of your teeth. In-office treatments may be costly, yet the results are the most dramatic. In-office treatments usually take about one hour and can whiten your teeth up to eight shades. These treatments also tend to reach all parts of your teeth. Since whitening treatments are not permanent, the best method is an in-office treatment with at-home maintenance, and regular follow-ups at your dentist.

Question 14 of 20 Correct

Peroxide can whiten the appearance of crowns or veneers.

Correct! Sorry, that’s incorrect.

The correct answer is: Peroxide won't bleach crowns or veneers. As a result, regardless of whether you choose an over-the-counter (OTC) or in-office whitening method, you may end up with a "technicolor effect," with your natural teeth being whiter than your restored teeth.

Smile Bright
Question 15 of 20 Correct

Which of the following is not a side effect of teeth whitening?

Correct! Sorry, that’s incorrect.

The correct answer is: Over-the-counter (OTC) whitening gels containing a level of 3.6 percent hydrogen peroxide (equivalent to 10 percent carbamide peroxide) are considered safe and will not harm the enamel on your teeth if used according to the directions. Professional treatments may contain higher levels of these ingredients, but they also contain fluoride to counteract any enamel damage. Common side effects from teeth whitening include gum irritation and increased tooth sensitivity to hot and cold food, as well as some inflamed nerve tissue causing mild to moderate tooth pain.

Smile Bright
Question 16 of 20 Correct

Which of the following foods is not a major culprit in staining your teeth?

Correct! Sorry, that’s incorrect.

The correct answer is: Blueberries, balsamic dressing and soy sauce are some of the most common foods that can stain your teeth. Other offenders include coffee, tea, cola, red wine, tomato sauce and curry. Health professionals do not recommend stopping use of these stain culprits, but rather limit their intake and make sure to brush or rinse your teeth after consumption.

Question 17 of 20 Correct

What foods are natural whiteners for teeth?

Correct! Sorry, that’s incorrect.

The correct answer is: Try adding these natural whiteners to your diet for brighter, healthier teeth: Strawberries are powerful teeth whiteners that contain both an astringent and vitamin C. The astringent in strawberries effectively aids in the removal of surface stains while vitamin C whitens teeth by clearing away plaque. Apples act like a toothbrush as you chew them. The process of chewing an apple removes excess food and bacteria from your mouth while scrubbing away surface stains. Apples also contain malic acid, a chemical used in teeth whitening products that helps dissolve stains.

Question 18 of 20 Correct

Which of the following is not a teeth whitening method?

Correct! Sorry, that’s incorrect.

The correct answer is: There are many alternatives to whitening, including in-office laser treatments, take-home whitening gels that are placed in a mouth tray and even rinsing with hydrogen peroxide. But neither you nor a health care professional should ever try to grind away stains, which could lead to dental abrasion, a destruction of the enamel and underlying dentin.

Smile Bright
Question 19 of 20 Correct

How long should you wait to brush your teeth after you use at home whitening strips?

Correct! Sorry, that’s incorrect.

The correct answer is: After you whiten your teeth at home, there is no time limit before brushing your teeth. However, it is advised that you clean your teeth by swishing water around your mouth following treatment. If you must brush, do so gently as your gums will be sensitive after whitening treatments. It is also suggested that you allow some time to pass between brushing and applying a whitening treatment to prevent gum irritation.

Smile Bright
Question 20 of 20 Correct

Do whitening toothpastes actually whiten your teeth?

Correct! Sorry, that’s incorrect.

The correct answer is: Whitening toothpastes do not whiten your teeth. These pastes contain mild abrasives that make your smile seem brighter. In reality, the toothpastes are really just grinding away stains. The major disadvantage of whitening toothpastes is these abrasives over time can thin tooth enamel and cause sensitivity.
