15 Myths & Facts About Cavities

There's a lot of information in the ether about dental health that isn't necessarily true -- especially when it pertains to what causes cavities and other form of tooth decay. That's why Dr. Amorteguy, your SLO dentist, would like her readers to read this post about the myths and facts surrounding what causes cavities and what does not:
1. Sugar Is the Prime Cause of Cavities 
Myth, but it's almost a fact.
The truth is, acid produced by bacteria in your mouth is the cause of cavities, says Kimberly A. Harms, DDS, an American Dental Association consumer advisor and former president of the Minnesota Dental Association. However, these bacteria are triggered to make acid when you eat anything with carbohydrates -- and sugar is a carb.
Rice, potatoes, bread, fruits, and vegetables are also carbs. 
Once the acid eats into your tooth, the bacteria “have a nice little hole to live in where your toothbrush and floss can’t reach,” says Harms. The bacteria continue to metabolize carbs and produce acids -- and your cavity just keeps getting bigger. 
Here’s an important fact. It’s not the amount of carbs you eat that causes tooth decay, but the length of time your teeth are exposed. If you eat a lot of carbs for lunch, that’s one big exposure. But if you spend the day sipping sugary drinks, that’s continuous exposure -- and much more unhealthy for your teeth. 
“We have a saying,” says Harms. “Sip all day and get decay.”
2. Exposure to Acidic Foods, Like Lemons, Causes Tooth Decay
Fact. Acidic foods such as lemons, citrus juices, or soft drinks don’t cause cavities, but they may be putting your enamel in danger. 
"Acids can tear down your enamel and weaken your tooth," says Harms. “If you lose the enamel's protection and expose the underlying dentin, your tooth is now more prone to decay.” 
3. Kids Are a Lot More Likely to Get Cavities Than Adults
Myth. With the help of sealants, fluoridated water, and preventive care, “we’ve actually cut decay in school-aged children by half in the last 20 years,” says Harms.
However, there’s been an increase in cavities in senior citizens “because they have some unique circumstances,” she says. Some medicines dry out the mouth, for example, reducing salvia. Saliva is vital in fighting tooth decay because it helps neutralize acids, has a disinfectant quality, washes away bacteria, and helps prevent food from sticking to your teeth.

Could Your Toothbrush Be Making You Sick?


Do you know what's lurking on your toothbrush?
Your toothbrush is loaded with germs, say researchers at England's University of Manchester. They've found that one uncovered toothbrush can harbor more than 100 million bacteria, including E. coli bacteria, which can cause diarrhea, and staphylococci ("staph") bacteria that cause skin infections.
But don't panic. Your mouth wasn't exactly sterile to begin with. 

Mouthful of Bacteria

"The bottom line is, there [are] hundreds of microorganisms in our mouths every day," says Gayle McCombs, RDH, MS, associate professor and director of the Dental Hygiene Research Center at Old Dominion University.
That's no big deal. Problems only start when there is an unhealthy balance of bacteria in the mouth. McCombs says.
"It's important to remember that plaque -- the stuff you're removing from your teeth -- is bacteria," says dentist Kimberly Harms, DDS, consumer advisor for the American Dental Association. "So you're putting bacteria on your toothbrush every time you brush your teeth."

Could Your Toothbrush Be Making You Sick?

Probably not. Regardless of how many bacteria live in your mouth, or have gotten in there via your toothbrush, your body's natural defenses make it highly unlikely that you're going to catch an infection simply from brushing your teeth.
"Fortunately, the human body is usually able to defend itself from bacteria," Harms says. "So we aren't aware of any real evidence that sitting the toothbrush in your bathroom in the toothbrush holder is causing any real damage or harm. We don't know that the bacteria on there are translating into infections."
Still, you should exercise some common sense about storing your toothbrush, including how close it is to the toilet.

Don't Brush Where You Flush

Most bathrooms are small. And in many homes, the toilet is pretty close to the bathroom sink where you keep your toothbrush.
Every toilet flush sends a spray of bacteria into the air. And you don't want the toilet spray anywhere near your open toothbrush.
"You don't store your plates and glasses by the toilet, so why would you want to place your toothbrush there?" McCombs says. "It's just common sense to store your toothbrush as far away from the toilet as possible."
You also wouldn't eat after going to the bathroom without first washing your hands. The same advice applies before brushing your teeth, McCombs says.

Toothbrush Storage Tips

Once you've moved your toothbrush away from the toilet, here are a few other storage tips to keep your brush as germ-free as possible:
  • Keep it rinsed. Wash off your toothbrush thoroughly with tap water every time you use it.
  • Keep it dry. "Bacteria love a moist environment," Harms says. Make sure your brush has a chance to dry thoroughly between brushings. Avoid using toothbrush covers, which can create a moist enclosed breeding ground for bacteria.
  • Keep it upright. Store your toothbrush upright in a holder, rather than lying it down.
  • Keep it to yourself. No matter how close you are to your sister, brother, spouse, or roommate, don't ever use their toothbrush. Don't even store your toothbrush side-by-side in the same cup with other people's brushes. Whenever toothbrushes touch, they can swap germs.

Do Toothbrush Sanitizers Really Work?

Various products pledge to sanitize your toothbrush. Some say they kill bacteria with heat or ultraviolet light, germ-killing sprays, or rinses. Others have built-in antibacterial bristles.
There's evidence that at least some of these products do effectively kill germs. But there's no real proof that using any toothbrush sanitizer will reduce your risk of getting sick.
If you choose to use one of these products, make sure that it has been reviewed by the FDA, which checks the validity of consumer health product marketing claims.
Remember that even the best products won't kill all the germs on your toothbrush. At best, they'll kill 99.9% of the germs.
That means if you have one million bacteria on your toothbrush to start, you'll still have about 1,000 remaining when you're finished sanitizing, Harms says.
Some web sites recommend putting your toothbrush into the microwave oven or dishwasher to sanitize it. Although these methods will kill some of the bacteria, they will probably damage your toothbrush in the process. It's better to just buy disposable brushes and throw them out.

When to Toss Your Toothbrush

The best way to limit the bacteria on your toothbrush is to replace it on a regular basis.
The American Dental Association recommends throwing out your toothbrush every three to four months. If the bristles become frayed, you're sick, or you have a weak immune system, throw it out even more often. If you use an electric toothbrush, throw out the head as often as you'd discard a disposable toothbrush.
Every time you're tempted to skip brushing and flossing your teeth, remember how many bacteria lurk in your mouth – and what they can do.
"It's bacteria that cause gum disease, and decay, and bad breath," Harms says. "Make sure you're brushing and flossing as often as possible to eliminate some of those bacteria." Rinsing your mouth with an antibacterial mouthwash before or after brushing can also help reduce plaque-causing bacteria that can lead to gingivitis, an early, mild form of gum disease.

10 Toothbrushing Mistakes


Toothbrushing is such an ingrained habit, few people think twice about it. But as with any habit, you can get sloppy, and that can lead to cavities and gum disease.

Toothbrushing Mistake No. 1: Not Using the Right Toothbrush

Consider the size of your mouth when picking a toothbrush, says Richard H. Price, DMD, the consumer advisor for the American Dental Association. "If you are straining to open wide enough to let the brush in, the brush is probably too big," he says.
''The handle has to be comfortable," he says. It should feel as comfortable as holding a fork when you eat.
"The more comfortable it is in your mouth and your hand, then the more likely you will use it and use it properly," he says.
Which is the better toothbrush: Electric or manual? 
"It's an individual preference," says Michael Sesemann, DDS, president of the American Academy of Cosmetic Dentistry and an Omaha dentist.  "A person who brushes well with a manual will do as well as a person who brushes well with an electric."
Price agrees. "It's not the toothbrush, it's the brusher."

Toothbrushing Mistake No. 2: Not Picking the Right Bristles

Some toothbrushes have angled bristles, others straight. So is one type better? Dentists say no.
''It's more related to technique than the way the bristles come out," says Sesemann.
What is important when buying a toothbrush? Bristles that are too stiff can aggravate the gums. The ADA recommends a soft-bristled brush.
''Bristles should be sturdy enough to remove plaque but not hard enough to damage [the teeth] when used properly," says Price. He doesn't recommend "natural" bristles such as those made from animal hair or boar bristle.

Toothbrushing Mistake No. 3: Not Brushing Often Enough or Long Enough

Softly brushing your teeth at least twice a day is recommended. ''Three times a day is best," says Sesemann.
With too much time between brushings, he says, bacterial plaque will build up, boosting the risk of gum inflammation and other problems.
Brushing should last at least two minutes, says Sesemann. Three minutes is even better, says Price.
Most people fall short of both time lines, says Sesemann. "It's an arbitrary number, but it's just so people take the time to clean all the surfaces." He often recommends people divide the mouth into quadrants and spend 30 seconds a quadrant. Some electric toothbrushes include built-in timers.  
To make the two minutes go faster, Sesemann says he ''multitasks,'' fitting in a little TV viewing as he brushes.

Toothbrushing Mistake No. 4: Brushing Too Often or Too Hard

While brushing your teeth three times a day is ideal, more may not be, says Sesemann. "More than four toothbrushings a day would begin to seem compulsive."
Excessive brushing could expose the root of the tooth to irritation, and that could in turn irritate the gums. Brushing vigorously can also erode tooth enamel. The trick is to brush very gently for two to three minutes.

Toothbrushing Mistake No. 5: Not Brushing Correctly

''Long horizontal strokes along the gumline can lead to abrasions," says Sesemann. "Aim your bristles at the gum line at a 45-degree angle and do short strokes or vibrations." Softly brush up and down your teeth, not across your teeth. The strokes should be vertical or circular, not horizontal.
Be sure to brush outer and inner tooth surfaces, the chewing surfaces, and your tongue.

Toothbrushing Mistake No. 6: Starting in the Same Place Each Time

Many people start brushing the same part of their mouth over and over, dentists find.
"Start in a different place so that you don't get lazy in the same area of your mouth," says Price. He reasons that by the time you get to the last quadrant of your mouth, you're bored with brushing.

Toothbrushing Mistake No. 7: Skipping Inner Tooth Surfaces

Most people forget to brush the inner surfaces of teeth -- the surface that your tongue presses against.
"The plaque you can't see is just as important to remove as the plaque you can see," says Price.  
The most commonly skipped area, dentists say, is the inner surface of the lower front teeth.

Toothbrushing Mistake No. 8: Not Following Up With a Rinse

Bacteria can grow on an un-rinsed toothbrush. Then, the next time you brush your teeth, you may actually put old bacteria back in your mouth, says Laurence Rifkin, DDS, a dentist in Beverly Hills, Calif.
Rinsing the toothbrush after you brush will help remove any leftover toothpaste, too.

Toothbrushing Mistake No. 9: Not Letting the Toothbrush Dry

"If you have a toothbrush that's perpetually moist, it will cultivate more bacteria," says Sesemann.
"If the bristles stay soggy, you can misshape them as you use the brush," Price says. "Or it might be a breeding ground for bacteria."
It's a good idea to shake out the moisture, then recap it with a cap that allows air in, he says.

Toothbrushing Mistake No. 10: Not Changing the Toothbrush Often Enough

The American Dental Association recommends getting a new brush every three or four months, or even sooner if the bristles look frayed.
But rather than go by a strict timeline, Price says a visual inspection of the bristles is better. "Once the bristles lose their normal flexibility and start to break apart, change your toothbrush," he says.
"Look more at the state of the bristles than the time period," he says.
Some brushes have colored indicators that alert you when they need replacing, says Price.

Everyday Habits That Ruin Your Teeth


You plan meals, grab drinks, and play sports without giving much thought to your teeth. But you might not realize how food, beverages, and activities can wreck the health of your pearly whites. Twenty-five percent of U.S. adults over age 65 have lost all their teeth - here's how you can protect your own.

Sugar and Teeth

Sugar is the No. 1 enemy of your teeth, and the longer it stays in your mouth, the worse it is. Sugar is consumed by acid-producing bacteria in your mouth. The acids eat away at tooth enamel. Avoid foods like jelly candies, which stick in your teeth longer than other foods and bathe them in sugar. Dried fruit such as raisins are no better. Reach for fresh fruit instead.

Beverages and Teeth

Soda is just plain bad for teeth, sugar-free or not. "You're bathing teeth in an acid environment," says Robert Sorin, DDS, clinical instructor in the department of dentistry and oral surgery at New York-Presbyterian Hospital. Club soda is harmful, too, because of its acidity, and so are juices with added sugar.
Alcohol, even just a glass of wine, is also acidic and can erode the teeth. In addition, alcohol dries out your mouth, reducing saliva production. "Saliva bathes the teeth and helps remove plaque and bacterial accumulations from the teeth's surface. Less plaque equals less risk for bacterial acids to cause decay," Sorin says. Rinse your mouth with water between drinks.

Other Risks to Teeth

If you use your teeth to snap off bottle caps, remove clothing tags, or open plastic bags, stop immediately. Smokers should also consider how the habit affects oral health. Nicotine yellows teeth and can also cause oral cancer. Chewing tobacco is even worse because the tobacco and associated carcinogens come into direct contact with the gums and soft tissues and stay there for a long time.
Also, ask your doctor or pharmacist if your medicines might cause dry mouth. According to the American Dental Association, more than 500 medications -- from pain relievers to antihistamines -- can do so. Dry mouth inhibits saliva production and increases your risk of cavities.
If you play contact sports, pick up a mouth guard at a sports store or have your dentist make you a custom one for maximum protection and comfort.
You don't even have to be awake to damage your teeth. Sorin says as many as 8% of Americans grind or clench their teeth, especially at night. If this is you, make an appointment with your dentist right away.
