About This Quiz

What's the name of the most common bacteria that causes tooth decay?
Streptococcus mutans attaches to your teeth via a sticky molecule called glucan and contributes to plaque buildup.
The layer of the tooth just below the enamel is called:
Dentin, like the enamel that covers it, can be prone to decay from bacteria.
The process by which tooth enamel decays over time is called:
Demineralization gets this name because calcium and phosphate are leached from the hard surfaces of the teeth.
The first water fluoridation program began in 1945 in which city?
Grand Rapids, Michigan. And, according to the American Dental Hygienists' Association, water fluoridation has reduced tooth decay in the United States by 50 to 60 percent since it started.
Water fluoridation can reduce dental decay in adult teeth by how much?
Nearly 35 percent. Fluoride not only helps remineralize teeth, it can also keep bacteria from producing excessive acid in the mouth.
For most cities, every $1 invested in water fluoridation saves how much in dental costs?
$38.00. Plus, think about what you'll save by not buying all that bottled water!
You can use this to show spots of plaque on your teeth:
Green food coloring. Try it the next time you brush. It'll show you the spots you missed!
Cooking food in this can increase its fluoride content:
Teflon is actually a substance called polytetrafluoroethylene, which contains flouride atoms.
What has more than twice the fluoride of black tea?
Green tea has double the flouride of it's black counterpart. But red wine can help, too, thanks to its concentration of polyphenols, which can kill decay-causing bacteria in the mouth.
Theobromine, a substance that can help strengthen tooth enamel, is found in what?
Chocolate lovers, go ahead and cheer. To get all of the benefits found in cocoa, be sure to buy dark chocolate that is at least 70 percent pure cocoa.
Which of the following is effective at killing decay-causing streptococcus mutans bacteria?
Licorice is the big winner here. But for it to be effective, you need to find pure licorice -- not the sugar-saturated kind in candy stores.
Which of the following foods can help keep plaque from attaching to teeth?
Olive Oil contains oleuropein, a substance that keeps the bacteria that causes gum disease and bone loss from attaching to teeth.
Calcium, important for strong teeth, can be found in all of the following except what?
Coffee may be good for alertness, but it's not a good source of calcium. If it's calcium you're after, try canned salmon or sardines (with their soft bones), dark leafy green vegetables, low-fat dairy, Brazil nuts and sunflower seeds.
Which vitamin can help your body absorb calcium?
Your body uses vitamin D to produce a hormone known as calcitriol, which the body can metabolize.
This substance in chewing gum makes it an extra-effective cavity fighter:
Studies show that Xylitol inhibits streptococcus mutans and keeps it from sticking to the teeth.
Eating cheese after a meal has been shown to reduce enamel damage by how much?
Cheese is especially good after a meal, as it neutralizes acid and produces beneficial saliva to wash sugars and starches away -- reducing enamel damage by as much as 71 percent!
Which of the following can harm teeth?
Carbonated water contains carbonic acid, which can erode enamel.
Approximately what percentage of adults age 20 to 64 have no teeth?
It's a relatively low number, but it might have been even lower if those 5 percent without teeth had taken this quiz!
What percentage of adults 20 to 64 have had cavities?
Maybe it's time to think about switching careers to dentistry -- 92 percent of adults 20 to 64 need to have at least one cavity filled!
What percentage of seniors 65 and over have untreated tooth decay?
Even the 23 percent who haven't had their tooth decay addressed can still strengthen their teeth with a combination of good eating habits and dental hygiene.
