Why do some people have really bad breath?

One of the most awkward scenarios people have to deal with every now and then is having a conversation with people suffering from chronic bad breath.

We all know how uncomfortable and hard it is to endure the bad odor coming from the other person’s mouth and we can’t help but wonder why they haven’t figure out a way to solve the issue. The truth is, it may not be entirely their fault.

According to a TED-Ed video produced by Mel Rosenberg, a bad breath expert, the gram-negative bacteria in our mouths are responsible for producing the foul odor causing a smelly breath. Based on Rosenberg’s explanation, these microorganisms break down organic matter such as mucus, dead tissue, as well as food remnants into much smaller molecules in order to absorb nutrients through their cell membranes. The break down process creates foul-smelling byproducts such as cadaverine and hydrogen sulfide.

Fortunately, there are many ways to combat bad breath such as brushing, flossing, using antibacterial mouthwash, cleaning the back of your tongue and eating healthy breakfasts.

However, some people may still have trouble getting rid of bad breath, particularly those with dental problems, nasal conditions,  and rare ailments such as uncontrolled diabetes and liver disease. People who smoke and consume alcohol excessively may also struggle combatting the off-putting smell.
