After a nap or a good night's sleep, bad breath is a normal and natural phenomenon.
A phenomenon, scientifically called halitosis, which can be extremely annoying if it persists throughout the day.
Bacteria produce gases
The cause? The proliferation of bacteria in the mouth, which, as reported by the Belgian media RTBF, hosts more than 600 different species. These bacteria primarily feed on dead cells from the oral mucosa and food debris on the tongue and teeth. An oral population that's perfectly normal, just like the result of their digestion, which leads to the production of gases. At night or during a short rest phase, the bacteria accumulate a lot of gas, resulting in bad breath.
Saliva plays a role in reducing the development of microorganisms and the associated gas production. However, when we sleep, we secrete less saliva and consequently, promote the growth of bacteria.
Other responsible factors
But why, in some people, does halitosis not disappear after a good brushing of teeth and persist even throughout the day? While there are many causes, here are the most common:
