Have you thoroughly brushed your teeth, rinsed your mouth, used a toothpick and floss, and you still get a bad smell in your mouth in the morning? The reason is not poor dental care, but bacteria that prefer a moist, warm environment in our mouth. Breeding microbes that produce foul-smelling compounds are the main culprits of the bad smell, which, unfortunately, nothing can be done about.
The best thing is to brush your teeth immediately when you wake up. Toothpaste and mouthwash containing ingredients such as xylitol, triclosan and essential oils create an unfavorable environment for bacteria. But the effects of these ingredients are short-lived. After a while, all these substances are washed away, and the bacteria begin to multiply again.
So why does the situation get worse at night? The thing is that saliva production is significantly reduced at night and the liquid that washes away these bacteria is present in very small quantities. As a result, over many hours, the “odorous” concentration increases and creates an unpleasant odor.
This is not about a few foul-smelling compounds, but about a variety of types that colonize different areas of the mouth. Scientists estimate that there are more bacteria in our mouths than there are people on Earth. The decomposition of microbes leads to bad breath.
Some of the amino acids that bacteria feed on contain sulfur, which contributes to the bad smell. In addition, the components of bad breath are: cadaverine (the smell of a corpse), hydrogen sulfide (the smell of rotten eggs), isovaleric acid (the smell of sweaty feet), methyl mercaptan (the smell of excrement), putrescine (the smell of rotting meat) and trimethylamine (the smell of decaying fish). You could say that we're getting the worst odors imaginable in our mouths.
In other words, we have a huge bouquet of disgusting scents in our mouths all night long, which explains why morning kisses lose their romantic touch a little bit.
