The main reason for bad breath when smoking is found to be caused by the chemicals found in cigarettes. These chemicals build up in your mouth. The tar and nicotine from your cigarettes are deposited in your mouth. Chemicals can stick to places like the teeth, gums, tongue and side of the cheeks. This causes smoker's breath to form.

One of the major results of the chemicals in the cigarettes is that it allows bacteria to form in your mouth. Once bacteria are introduced into your mouth they will stay in your mouth until you get rid of them. Your mouth is a constantly we environment that bacteria thrive on. When they stay on your mouth's surface, it allows the bacteria to stick to certain places, giving them a place to thrive.

Another reason why smoking causes bad breath, is because it dries out your mouth. This stops the saliva from continuously flowing and cleansing out your mouth. This is what causes the growth of certain types of bacteria in your mouth, which then lead to a continuous odor on your breath. Because the saliva is not able to move as freely, it can't clean out the bacteria that move through your mouth. These same parts of smoking also cause cavities and yellowing of teeth to form easier. It raises the temperature in your mouth. This causes oral tissue cells to be damaged and killed. These will then not be able to protect the mouth efficiently, causing the bacteria to be able to move into the mouth easier. This may eventually lead to more serious problems with your oral hygiene.

More serious problems with smoking and dental hygiene may include gum disease and oral cancer. The tobacco that moves into your system causes your immune system to limit how it can fight infection. It also stops the growing of blood vessels.

The easiest way to get over your bad breath is quitting smoking. You and everyone around you will breathe easier. If you are not able to totally quit smoking, just lessening your cigarette intake everyday will go a long way to increasing your health and your breath. It may be difficult to totally quit smoking but in the long run quitting smoking is a good idea for you and your family.
