"In one mouth, the number of bacteria can easily exceed the number of people who live on Earth (more than 6 billion)," says Sigmund Socransky, an associate clinical professor of periodontology at Harvard. "These bugs don't colonize your mouth in a random way; rather, they form communities in a pattern that is dictated both by other bugs and by the environment. Bacteria affect their environment, and the environment affects them. Although they touch each other, the floor of the mouth is populated by different communities than the bottom of the tongue, and the top of the tongue hosts a biota unlike that on the roof of your mouth."
So it is said that the mouth is like a mini jungle. To keep the mouth smelling as fresh as possible, we need to treat it as a garden instead by cleaning up and weeding out unwanted elements. Of course the first recourse is to brush the teeth regularly, at least twice a day—or after every meal. It will help to keep a toothbrush at the office so even at work you can take care of your mouth and teeth. There is some toothpaste that contains antibacterial agents that protect the mouth for up to 12 hours at a time.
You should also floss at least three times a week but if you want to get rid of bad breath, it is best to floss at least once daily. If you are wearing dentures, this should also be taken out and cleaned thoroughly every day. The tongue should also be cleaned with the use of a tongue scraper, because this is prime breeding ground for bacteria. It is said that more mouth odor is reduced by cleaning the tongue compared to brushing alone.
Keeping the mouth hydrated by drinking water or chewing sugar free gum also works in keeping bad breath at bay. The daily use of mouthwash also helps keeping the breath smelling fresh, and for those who want longer and stronger breath protection there are products that contain compounds like chlorhexidine that kills much more bacteria in the mouth, keeping it fresher for longer. The diet also play a role in how our breath smells, as the air that we expel is laced by the smell from our stomach content. Avoid foods with strong odors such as garlic, onions and spices if you are about to go on that first date.
Your bad breath may also be caused by more serious problems like gastric problems and/or periodontal diseases, so it’s important to consult with your dentist if the problem persists and does not go away even after a combination of home treatments. The medical term for chronic and severe bad breath is halitosis, and help is available through your dentists if this is the case. You should also schedule a dental cleaning twice every year to get rid of tartar accumulation in the teeth.
