Mistakes You Make Brushing Your Teeth‏

Brushing your teeth: It’s something you (should) do twice a day, every day. But it’s not as a simple as just scrubbing and rinsing.Timothy Chase, D.M.D., a New York City-based cosmetic dentist, says these are the flubs most people make:

1. Using the wrong toothbrush

All toothbrush bristles have a rating — hard, medium, soft, and extra soft. Just ignore the medium and hard bristles altogether, says Chase. “I see a tremendous amount of [gum and tooth] damage from brushes that are not soft enough. Imagine you have a broom and you’re trying to get dust out of a corner. If you had a really stiff broom, you’d wind up scuffing up the wall. A soft broom would take the shape of a corner and remove the dust easily,” he says. The same goes for your toothbrush.

2. Using an old brush

You should buy a new toothbrush or, if you use an electric toothbrush, replace the head every three months. If you forget, pay attention to the bristles. When they begin to feel soft and lose their original shape, it’s time to pitch it (or at least retire it to the cleaning cabinet).

3. Not going in circles 

Every dentist will say it: The correct way to brush your teeth is in small circular movements. Remember that the only thing you should be removing is leftover food debris — not brushing so hard that you ruin your enamel. “Most people use a sawing motion back and forth, which can cause damage to the gums and tooth abrasion. This can lead to root exposure and sensitivity,” Chase says.

4. Using whitening toothpaste

“You don’t get a great result from whitening toothpaste,” warns Chase. “Instead, use a cavity-fighting toothpaste, and then use trays or white strips independent of brushing.” Another tip: Only squeeze out a pea-sized amount of toothpaste. “A good rule of thumb is half the brushing surface,” he says.

You only need to use a mouthwash if you like it, and if you’re going to use it, stick with an alcohol-free variety. (Chase likes Listerine Zero.) Your mouth needs saliva in order to clean itself, and alcohol can dry out your mouth. And before making your kids rinse with a fluoride mouthwash, check with your pediatric dentist. “Don’t just automatically assume your kids should use one,” says Chase.

8. Not brushing for long enough

Chase recommends that his patients spend a full two minutes brushing. There are some electronic toothbrushes that will automatically stop after two minutes, or simply use a timer until you get the timing down.

9. Not considering an electric toothbrush

It’s worth it to invest in a quality electric toothbrush, says Chase. It does all of the work for you and doesn’t overpoweryour teeth. But don’t be persuaded by the disposable electric toothbrush. “Some of the disposal electric toothbrushes cheap out on the most important part, which is the bristle,” he says. “Generally the bristles are so hard that you cause a lot of damage.”

Ways You’re Ruining Your Teeth

You only get one set of choppers, and repair costs more than prevention. So be kind to your teeth. Here are some mistakes you may not know you’re making.

Brushing Too Hard

“If you brush too vigorously, you can wear away at your enamel and cause sensitivity and even gum recession,” says dentist Nuntiya Kakanantadilok, director of the division of pediatric dentistry at Montefiore Medical Center in New York City. Buy a brush with soft bristles and move it in small circles, not side to side, she says.

Eating too Many Acidic Foods

“They can wear away enamel,” says Kakanantadilok. That’s a problem because that top protective layer of the teeth can never grow back. Nerves below it lose their protection, and you may start to feel pain from hot or cold. Some acidic, erosion-causing culprits: regular (and diet) soda, orange juice, wine, sports drinks, sour gummy candies, and lemons. “Think about your tooth as a seashell,” says dentist Martha Ann Keels, division chief for pediatric dentistry at Duke Children’s Hospital. “If you put a seashell in Coke, it will disappear.”

If you can’t resist these dental no-no’s, at least neutralize the pH in your mouth by consuming water or cheese with them, says Keels. And instead of swishing acidic drinks around your in mouth, use a straw to limit contact with teeth, says dentist Richard H. Price, an American Dental Association consumer adviser.

Too Much Teeth Whitening

It’s normal to want pearlier whites. After all, says Price, “As we get older, teeth get darker.” But don’t overdo it. “Basically, you’re exposing your teeth to a very mild acid,” says Kakanantadilok. “Excessive bleaching can weaken enamel. Over time, even mild acid can begin to erode the mineral content of the tooth, causing the enamel to become porous and eventually to break down and become more sensitive.”
Kakanantadilok says over-the-counter white strips are milder than in-office bleaching systems. And who wants teeth that look like Chiclets gum, anyway? “We try to educate people that ‘normal’ tooth color is not white but more ivory,” says Paul Casamassimo, director of the Pediatric Oral Health Research and Policy Center for the American Academy of Pediatric Dentistry.

Chasing Hot Pizza With a Cold Drink

When you bite into a piece of hot pizza, you’re expanding your enamel. “Then you take a big dose of cold cola, not with a straw, and you’re going to cause contraction,” says Price. That can create what’s called a “craze line” — a vertical, hair-thin crack in the enamel that can lead to breaks and stains. “It would be similar to what happens to a porcelain plate that goes from hot to cold,” says Price.
“Teeth will contract or expand with changes in temperature,” says Casamassimo. “When that happens, if it’s done too quickly, it’s damaging.” One solution: Like Price, eat hot pizza with a knife and fork.

Using the Wrong Toothpaste

Pick one that’s not too abrasive: The FDA rates toothpastes using a “relative dentin abrasion” (RDA) scale. Anything above 100 is considered abrasive, above 150 is highly abrasive, and above 200 is not recommended, says Kakanantadilok. For your reference: Colgate Total gets 70, Colgate Baking Soda & Peroxide Whitening Toothpaste gets 145, and Arm & Hammer Dental Care PM gets 168.

Using Them As a Tool

You might think this sounds crazy, but lots of people do this absent-mindedly. “The teeth are meant to chew foods and look pretty when you smile, not to open up candy wrappers or chomp down on ice cubes,” says dentist Warren Brill, president of the American Academy of Pediatric Dentistry.

If you use your chompers to open nail polish bottles, beer bottles, or anything else, you can cause micro-fractures that may not be apparent for years, says Kakanantadilok. Such abuse can also cause teeth to break or fillings to pop out.

Not Brushing and Flossing Enough

Some people think this is enough — some people are wrong. Brush for two minutes a day, twice a day. Otherwise, you increase the odds that you’ll get cavities, which, if untreated, can spread into the jaw and cause infections. If you’re at work and can’t get to your toothbrush, a good solution is to keep a box of dental floss in your purse or drawer. “Floss first, if that’s all you can do,” says Keels.
