Maybe this may interest you:
Certain foods, especially garlic and onions, which contain intense oils, can contribute to bad breath because the oils are carried to the lungs and then out through the mouth. Smoking is also a major cause of halitosis.
There are many myths about the care of bad breath. These are three things you may have heard about bad breath that are not true:
Myths about why bad breath occurs
Myth #1: If you breathe in your hand you will know that you have bad breath.
Error! When you breathe, you do not use your throat the same way you do when you speak. When you speak, you tend to draw odors from the back of your mouth (where bad breath originates), and this does not happen when you breathe. Also, as we usually get used to our own smells, it is difficult for a person to notice if they have bad breath.
If you are worried about your bad breath, make sure you take care of your teeth and your mouth properly. Some chewing gums and mints without sugar can also cover odors temporarily.
If you brush and floss your teeth properly and visit your dentist for regular cleanings, but your bad breath persists, you may have a medical problem such as sinusitis or gum disease. Call your doctor or dentist if you suspect a problem. They can discover if there is any other problem behind your bad breath and can help you solve it.
Myth #2: Mouthwash will make bad breath go away.
Mouthwash only eliminates bad breath temporarily. If you use a mouthwash, look for one that is antiseptic (kill the germs that cause bad breath) and reduce the plaque, with a seal from the Association of Dentists of the United States (ADA). When deciding which dental products to place in your shopping cart, it is always a good idea to look for those that are accepted by the ADA. Also, ask for recommendations from your dentist.
Myth #3: While you wash your teeth, you should not have bad breath.
The truth is that most people only brush their teeth for 30 to 45 seconds, which is not enough. To clean all surfaces of the teeth efficiently, you should brush them for at least 2 minutes, at least twice a day. Remember to brush your tongue too, bacteria love to stay there. It is also important to floss because only brushing will not remove the harmful plaque and food particles that stick between the teeth and gums.
