Some complete their tooth brushing under a minute while some require more than that. But no matter how quick or how long you brush your teeth, it does not ensure that you will no longer have bad breath. Since bad breath is caused by several factors like the food you eat and some medical condition, it does not guarantee that brushing alone will prevent bad breath. Dentist require you to brushing your teeth at least 2 times a day, using dental floss or other type of inter-dental brush at least once a day, and an oral antiseptic with safe level of alcohol content. A regular visit to the dentist would also keep your dentures healthy. Other reasons why people suffer from chronic bad breath are regular intake of food, drinks and products that either degrade the quality of air you breathe or help produce more bacteria inside your mouth. This is simply because the mouth and the nose are connected in some sort at the back of the mouth. And our noses by nature, have the tendency to filter out the background odors. Thus, we cannot readily discern if our breath smells bad already. But so much for that, you must also be aware of the conditions that cause the breath to acquire its unpleasant odor. Smokeless Tobacco If you switched to smokeless tobacco because you become aware that smoking tobacco causes bad breath, then you are not making any good. Smokeless tobacco is still a tobacco product and causes bad breath. Aside from that, smokeless tobacco can cause oral cancer, softening of the oral cavity, nicotine addiction, blood alteration, and gum effects. Any foreign object trapped in the nose of your child can prevent a free flow of air on the nostrils which makes breathing hard. This also forces your child to breathe to his mouth and will, in turn, dry his mouth. 2. Periodontal diseases. Bad breath is also associated with periodontal diseases such as tooth decay, gingivitis, and plaque. Saliva helps wash away and cleanse bacteria inside our mouth thus it helps keep our breath fresh. The production of saliva stops when we sleep; the reason why we wake up in the morning with the "morning breath" even if we brush our teeth and use oral antiseptic the night before. Smoking tobacco and other medication also contribute to the occurrence of bad breath.
