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 just don't brush long enough. Most people 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 infection 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 the teeth, inside the tooth, your tongue,
and especially brush 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 2-3 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
45-70 seconds twice a day.
Electric vs. manual toothbrushes
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 captivates 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. Most electric toothbrushes have rechargeable batteries that take
10 to 45 minutes to recharge. The gearing in an electric toothbrush
occasionally must be lubricated with water. Prices range from $30 to $99.
How do electrics 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 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.
How long have toothbrushes been used?
The first toothbrush was invented in China in 1000 A.D. It was an
ivory-handled toothbrush with bristles made from a horse's mane.
Toothbrushes became popular in the 19th century among the Victorian
affluent. Mass marketing and the advent of nylon bristles in the 20th century
made toothbrushes inexpensive and available to everyone.
Don't forget . . .
Visit your dentist regularly because toothbrushing and flossing is most
effective with periodic checkups and cleanings.
