Brushing your teeth could help you avoid heart disease. Having clean teeth and healthy gums may cut your chances of atherosclerosis.
The bristles move a lot faster on an electric toothbrush compared to an ordinary manual toothbrush. Therefore it is better at removing plaque and brushing between ones teeth.
The ADA (American Dental Association) does not endorse either a normal toothbrush or an electric toothbrush. In fact, power and normal toothbrushes can have similar effects if used properly. Power toothbrushes do have a better maneuvering power, they can get around the gums and sides of teeth better and with less trouble.
Any dentist will tell you what you already know, that your manual toothbrush just won't do the same cleaning job as an electric toothbrush. The main reason for this is obvious, because an electric motor is able to move much faster than a human hand will ever be able to. With a standard toothbrush, if you are in a hurry, say in the morning before work, or of an evening before going out, you can rush brushing.
The electric or power toothbrush on the other hand is part of the new wave of technology. The power toothbrush has a rechargeable battery case that can be plugged into any outlet so that you dont have to buy new batteries every time they run out. The recommended time for cleaning your teeth is 2 minutes. Many toothbrushes come with a timer which will tell you when those two minutes are up.
Some of the hi-tech features of the power toothbrush include: various brushing modes, some for sensitive teeth or whitening and gum massaging features; pressure signals to indicate when brushing too hard; timers to time the length of brushing each quadrant of the mouth; digital reminders to alert when it is time to change toothbrush head
As mentioned electric toothbrushes can give your teeth a real thorough clean, although you do still need to visit the dentist regularly for check ups.
The dentist might recommend a switch to a power toothbrush because of all the features mentioned above. Whatever the recommendation may be, it is important to choose a toothbrush, either manual or electric, that is approved by the American Dental Association.
