How Do I Choose and Use a Toothbrush?
Angled heads, raised bristles, oscillating tufts and handles that change colors with use: you name it, toothbrushes come in all shapes, colors and sizes, promising to perform better than the rest. But no body of scientific evidence exists yet to show that any one type of toothbrush design is better at removing plaque than another. The only thing that matters is that you brush your teeth. Many people just don't brush long enough. Most of us brush less than a minute, but to effectively reach all areas and scrub off cavity-causing bacteria, it is recommended to brush for two to three minutes.
Which toothbrush is best?
In general, a toothbrush head should be small (1" by 1/2") for easy access to all areas of the mouth, teeth and gums. It should have a long, wide handle for a firm grasp. It should have soft nylon bristles with rounded ends so you won't hurt your gums.
When should I change my toothbrush?
Be sure to change your toothbrush, or toothbrush head (if you're using an electric toothbrush) before the bristles become splayed and frayed. Not only are old toothbrushes ineffective, but they may harbor harmful bacteria that can cause infections such as gingivitis and periodontitis. Toothbrushes should be changed every three to four months. Sick people should change their toothbrush at the beginning of an illness and after they feel better.
How do I brush?
Place the toothbrush beside your teeth at a 45-degree angle and rub back-and-forth gently. Brush outside and behind the teeth, your tongue and especially on chewing surfaces and between teeth. Be sure to brush at least twice a day, especially after meals.
How long should I brush my teeth?
You should brush your teeth at least two to three minutes twice a day. Brush your teeth for the length of a song on the radio, the right amount of time to get the best results from brushing. Unfortunately, most Americans only brush for 45 to 70 seconds twice a day.
Which is better, an electric or manual toothbrush?
Electric toothbrushes don't work that much better than manual toothbrushes, but they do motivate some reluctant brushers to clean their teeth more often. The whizzing sounds of an electric toothbrush and the tingle of the rotary tufts swirling across teeth and gums often captivate people who own electric toothbrushes. They are advantageous because they can cover more area faster. Electric toothbrushes are recommended for people who have limited manual dexterity, such as a disabled or elderly person and those who wear braces. Sometimes, it takes more time and effort to use an electric toothbrush because batteries must be recharged, and it must be cleaned after every use.
How do electric toothbrushes work?
Electric toothbrushes generally work by using tufts of nylon bristles to stimulate gums and clean teeth in an oscillating, or rotary, motion. Some tufts are arranged in a circular pattern, while others have the traditional shape of several bristles lined up on a row. When first using an electric toothbrush, expect some bleeding from your gums. The bleeding will stop when you learn to control the brush and your gums become healthier. Children under the age of 10 should be supervised when using an electric toothbrush. Avoid mashing the tufts against your teeth in an effort to clean them. Use light force and slow movements, and allow the electric bristle action to do its job.
Visit your dentist regularly because toothbrushing and flossing is most effective with periodic checkups and cleanings.
