Quiz: What Do You Know About Your Teeth? https://www.webmd.com/oral-health/rm-quiz-what-do-you-know-about-your-teeth

An orange a day prevents tooth decay.

〇 True

〇 False

False

Citrus fruits are highly acidic. They can wear down the hard outer covering of your teeth, called enamel. That makes your teeth more vulnerable to decay.
This doesn’t mean you have to skip your morning OJ, though. Just make sure to brush
afterward. Ideally you should wait 30 minutes after eating or drinking. And limit acidic
drinks, such as coffee or lemonade, for the rest of the day.

If you have a sugary drink, drink it quickly instead of sipping it all afternoon
— and brush afterward, if you can.

Bacteria that live on your teeth are a major cause of:

〇 Bad breath

〇 Cavities

〇 Both

Both

Bacteria thrive on bits of food on and in between your teeth, and they clump together to form a sticky film called plaque. Acids that come from bacteria in plaque wear away tooth enamel and can eventually create a hole or cavity. Plaque also causes gum disease, which can leave you with stubborn bad breath. Brush your teeth twice a day and floss and rinse with an antiseptic mouthwash at least once to keep plaque at bay.

When you're craving sweets, dried fruit is a tooth-friendly
alternative to candy.

〇 True

〇 False

url
from https://www.webmd.com/oral-health/rm-quiz-what-do-you-know-about-your-teeth

False

Dried fruit is sticky, which means it stays on the teeth longer than some sweets.
This provides an ongoing source of sugar that fuels bacterial growth.
So if you’re a fan of trail mix, rinse your mouth with water after snacking.
Brush and floss as soon as possible.

In infants, baby teeth may appear as early as:

〇 Birth

〇 3 months

〇 6 months

url
from https://www.webmd.com/oral-health/rm-quiz-what-do-you-know-about-your-teeth

Birth

About 1 in 2,000 babies is born with visible teeth.
In the typical baby, all 20 primary teeth are fully formed at birth, but they don’t start
emerging from the gums until around 6 months of age.

Baby teeth are whiter than adult teeth.

〇 True

〇 False

url
from https://www.webmd.com/oral-health/rm-quiz-what-do-you-know-about-your-teeth

True

The enamel on primary teeth is thinner, making them appear whiter than permanent teeth.
The color difference may be noticeable when kids have a mix of baby and adult teeth.

Dental sealants are only for kids.

〇 True

〇 False

url
from https://www.webmd.com/oral-health/rm-quiz-what-do-you-know-about-your-teeth

False

Whether you’re a child or an adult, your toothbrush can’t reach all the way into the
grooves of your teeth. That means some food and plaque will remain despite your best
efforts to take care of your teeth and gums. Dental sealants coat the chewing surfaces
to seal out plaque. One application will usually protect the teeth from decay for several
years.

A black hairy tongue comes from:

〇 A serious medical illness

〇 A harmless growth of bacteria

〇 Too much coffee

url

A harmless growth of bacteria

In some people, tiny projections on the tongue’s surface grow longer than usual.
This layer of “fur” harbors bacteria, which makes the tongue look darker.
Brushing, flossing, and rinsing with an antiseptic mouthwash regularly can control the
bacteria and restore the tongue’s normal appearance.

It's normal for teeth to be sensitive to hot and cold foods.

〇 True

〇 False

"Whitening" toothpastes work by:

〇 Removing stains from your teeth

〇 Bleaching the tooth enamel

〇 Coating the teeth with a film

Removing stains from your teeth

Whitening toothpastes are made with ingredients that scrub surface stains from the teeth.
They don’t change the baseline color of your tooth enamel. If you want to get your teeth
whiter than your enamel color, talk to your dentist about an in-office or at-home bleaching
treatment.

If you knock your tooth out, putting it in milk will help
preserve it.
