As I explained in last week’s post, there are bacteria in everyone’s mouth. Every time you decide not to floss your teeth or use a tongue scraping instrument, you allow bacteria to grow on and between teeth, around the gums, and on the tongue. Those bacteria lead to bad breath. Listerine and Altoids can only do so much to mask bad breath. I firmly believe that curing your bad breath starts with forming good oral hygiene habits and regular dental visits.
Smoking certainly does not help your cause. Tobacco products over time lead to periodontal (gum) disease, which can lead to what dentists call “perio breath.” Perio breath really stinks! Saliva plays an important role in protecting mouth from bacterial growth/insult. It washes away dead cells and neutralizes acids contained in plaque. Therefore, people who are on many medications and people whose salivary glands have been damaged are likely to have bad breath.
If I determine that your bad breath is due to underlying health conditions (digestive, respiratory, etc.) instead of underlying oral conditions, I most likely will refer you to a physician for evaluation of your digestive and respiratory systems and for appropriate treatment.
