What Causes Halitosis (Bad Breath)?

Acid Reflux

Research clearly indicates individuals who suffer from chronic acid reflux typically experience more cases of bad breath than those who do not. This is because the onset of acid reflux can cause stomach acids and gastrointestinal bacteria to enter the throat and mouth. The good news is that most of the time, all individuals need to do to get rid of halitosis in these cases is to rinse their mouth. However, there have been noted instances in which gut bacteria can infect the mouth cavity, and in some cases, bacteria, such as H. pylori (a bacteria that lives and grows in the intestinal tract) can create more complex medical problems.

Tobacco

Tobacco use, particularly cigarette smoking, can cause chronic ‘smoker’s breath,’ which is a foul odor on the breath that smells of the tobacco and chemicals from the cigarettes the individual was smoking. Although the smell is quite unpleasant, the long-term effects of smoker’s breath are much worse than just the smell. Research has found the chemicals and compounds released from smoking, particularly when individuals smoke a lot, can lead to dry mouth and a reduction in the salivary flow, and as many will be able to guess, can lead to a buildup of bad bacteria, resulting in prolonged bad breath.
