This is the most obvious reason for using a toothbrush, and the main reason for using the Sonicare toothbrush. Sonicare removed from between the teeth a lot more disease-causing plaque that a manual toothbrush .*

Soft brushed
Although the Sonicare toothbrush is powerful enough to remove plaque that hides in areas of difficult access and high risk, it is gentle on the gums and even those with sensitive teeth. Thanks to its extra soft bristles and his delicate cleaning action, Sonicare is as smooth as a manual toothbrush.
Gums healthier :
When plaque builds up between the teeth and gums, weaving them starts irritated, which can lead to gingivitis (inflamed gums), the most common disease of the gums. If the plaque is not removed thoroughly each day, gingivitis can worsen and lead to periodontal disease and periodontal pockets. The movement at high speed creates Sows of Sonicare action of fluid dynamic that goes in depth along the gumline, providing a unique experience of brushing. Sonicare can really reduce gingivitis and help reduce periodontal pockets.

Periodontal disease is a gum disease that is not unusual. Thus the Institute of Dental and Craniofacial Research  indicates that 80 percent of Americans have some form of gum disease or periodontal disease. The problem begins with the plate. ( "Oral Hygiene") The plate is not removed can harden and form bacteria that turns into tartar. Once this happens, the brush is not enough. Only a professional cleaning by a dentist can remove tartar.

If plaque or calculus are not removed, the bacteria cause inflammation of the gums called gingivitis. In gingivitis, the gums become red, swollen and may bleed easily. Gingivitis is a mild form of gum disease and is usually reversible with daily brushing and regular cleaning by a dentist. This form of the gum disease does not include any loss of bone and tissue that holds teeth in place.

When gingivitis is not treated, can advance to periodontitis. In periodontitis, gums backs out of the tooth forming pockets that become infected. The body's immune system resist the bacteria when the plate is scatters and grows under the gum line. Bacterial toxins and enzymes that attack the body infection usually start under the broken bone and connective tissue that holds the tooth in place. If left untreated, bones, gums and connective tissue that supports the teeth is destroyed. The teeth will eventually loosen and have to be removed.
 

A main problem with bad breath is that the only person not to notice it is the person affected. (You get used to your own smell and do not tend to notice your own bad breath.) Often, the only way to know about it is if a person comments on it. However, most people are too polite to comment on another person's bad breath. You may have to rely on a family member or a close friend to be honest and tell you if you have bad breath.
 
 Perhaps you could ask your dentist next time you have a check up. A dentist will normally be able to say if you have bad breath. Gum disease is a common cause of bad breath and a dentist will be able to advise on treatment if you have gum disease.
 
 Some people suggest a simple test which you can do yourself to detect bad breath. Lick the inside of your wrist. Wait a few seconds for the saliva to dry. Then smell the licked part of the wrist. If you detect an unpleasant smell you are likely to have bad breath.
 
 

In most cases of persistent bad breath, the smell comes from a build up of bacteria within the mouth - in food debris, plaque and gum disease, or in a 'coating' on the back of the tongue. Good oral hygiene will often solve the problem. That is, regular teeth brushing, flossing, cleaning the tongue, and antiseptic mouthwashes. Other causes of persistent bad breath are uncommon.

Bad breath, sometimes called halitosis, means that you have an unpleasant smell on your breath that other people notice when you speak or breathe out. The exact number of people with bad breath is not known, but it is common.

Children as young or two or three can have bad breath from postnasal drip, dental plaque and transient throat infections. However, if they develop sudden offensive odor that appears to come from all over their body, ask the physician to check whether they stuffed something up one of their nostrils
Some people have experienced small crumbly 'stones' in their mouths that have a foul smell. These are called 'tonsilloliths'. They are partially calcified, full of bacteria and develop in crypts in the tonsils. They smell pretty bad, but do not always cause bad breath.
