I brush my teeth everyday – why do I still get cavities?

There is a lot more to brushing your teeth than just showing up twice a day to do it. Improper brushing actually can cause damage to your teeth and gums. Too vigorous brushing can abrade your teeth and gums causing wear of the teeth and recession of the gums. When you wear away your gums and enamel, the exposed roots of the teeth can be at more risk for decay. Most people also brush too fast and don't spend enough time on all the surfaces of the teeth, leaving plaque behind that can cause decay.

Brushing techniques
Teeth should be brushed at least twice a day for at least two minutes at a time. The toothbrush should be held at a 45 degree angle – not flat against the teeth. You should brush in small circular motions rather than long broad strokes. Your toothbrush should not be touching more than two to three teeth at a time. Divide your mouth into four quadrants (upper right, upper left, lower right, lower left) and spend 30 seconds on each quadrant, brushing in front of and behind all the teeth.

Toothbrush Selection
Use a toothbrush with soft, nylon, round-ended bristles that will not scratch and irritate teeth or damage gums. While medium brushes are sold, only soft or very soft brushes are recommended. This is a case of less is more. The length of time you brush and the way you hold the brush are far more important than scrubbing hard. Pushing too hard with a brush or using a stiff brush is bad for your teeth and gums. Think of your teeth like fine china. You don't rub your fancy dishes with a Brillo pad and the same should go of your teeth.

Time for a new one
Remember to replace your toothbrush every three months. Researchers have established that thousands of microbes grow on toothbrush bristles and handles. Most of the microbes are harmless, but others can cause cold and flu viruses, the herpes virus that causes cold sores, and bacteria that can cause periodontal infections. It is especially important to switch to a new brush if you are getting over a cold or flu virus. When you notice the bristles looking frayed and splaying out, it is a good indicator that it is time for a new brush, as well as an indicator that you may be scrubbing too hard with your brush. Peterson Family Dentistry provides each patient with a new toothbrush at check-up time. In order to "stay green" we offer the Recycline "Preserve" toothbrush for kids and adults. The handle is made with recycled materials (like yogurt containers) and after you are done with the brush you can recycle it through the Recycline company to be used in plastic lumber for picnic tables, boardwalks, and decks. Their website is www.preserveproducts.com and you can download a postage-paid label there to recycle your toothbrush today!
