I would hope that everyone does. I brush mine morning and night, that's all that's necessary, but the more, the better. It is important to. My parents made sure I knew it was since they're both had dental problems, my dad's lost most of his because he didn't take care of them properly.

wow you only shave once a week? if I don't do it every day I look like frekin chewbacka! \n\nwell I should say most blades will last you probably at least 3 months with that little use.  When you start to notice its just not working as well is the best way to tell. you know when it leaves alittle stubble yet.

We usually clean it once a year when we get their teeth done. It's much easier cause they are drugged already.

Brush your teeth with a mixture of salt and baking soda 3-4 times a week. It is also the cheepest and the least abracive.

I use an Oral-B electric toothbrush.  Since changing from the manual brush my regular checkups have been greatly improved.  I can feel the difference in effectiveness between the two types.  Electric takes some getting used to, but there's no turning back.

Always get a second opinion. They are out to make money. I saw a dentist and he said I had 5 cavaties!!! I went to another and had only one small cavity. They will rip you off!!! Also, who in the heck needs a $100 toothbrush? Go buy a sonic care one at Target or Wal-Mart. They are the best. Take action and let them know that you are going elsewhere.

at least once a day, can be tricky to start with but you will get used to it the more u do it. you can also get interdental brushes now a day which ppl find easier but depends on spaces you have.

I believe the standard time is approximately 3 minutes. This is based on a moderate speed of brushing (which is not too fast as it may irritate your gums and may make them swollen or aggravated in cases of bleeding). You should also not vigorously brush your teeth for a long time because the natural coating and enamal of the crown of your teeth will dimish and thin. Having said all of this, it is still best to consult your trusted dentist for proper guidance on what is best to do with your brushing routine.

You should replace your toothbrush every 3 months or sooner if you are have had a cold or other illness.  If you have had a cold or other illness then replace toothbrush as soon as you are well.

Does an electric toothbrush really clean your teeth better than a manual toothbrush? Many dental experts say "no," maintaining that if you brush for two minutes at least twice a day, floss, and visit your dentist regularly, manual brushes and electric toothbrushes are equally effective. Some dentists note, however, that they've seen improvement in periodontal disease after patients started using an electric toothbrush. \n\nThe best reviews compare electric toothbrushes not only with other electric brushes, but also with manual brushing. Consumer Reports magazine does the best electric toothbrush testing in the U.S., enlisting testers who normally brush manually. Although not all tested toothbrushes are available in the U.S., Australia's Choice Magazine and England's Which? Magazine also compare electric toothbrushes with a test methodology equal to that of Consumer Reports. We found more scientific data at the Web site of the American Dental Association and The National Institute of Dental and Craniofacial Research.\n\nThe problem with any kind of toothbrush is that most of us just aren't very dentally self-disciplined. A number of articles we came across in our research say that most Americans brush for only 30 to 60 seconds, which is half the time recommended by dentists, and not nearly long enough to enable the fluoride in toothpaste to work properly. Reviews say the best electric toothbrushes come with a two-minute timer and are able to reach hard-to-clean areas better than most of us tend to do with a manual brush, making them a worthy addition to your collection of dental-hygiene products.

go to the dentist and have a thorough cleaning by the hygienist.  Then,  be sure to brush and floss every day.

you should brush your teeth  at least 3 times a day.  rinsing with something like listerine between those brushings helps too.  Make sure to brush after you eat something sugary.
