The smell of bad breath in the morning can be annoying, especially if you sleep with a partner.
It is caused by odor-producing bacteria that cause morning breath or halitosis. As we sleep, our mouth produces less saliva, leading to a proliferating bacterial population.
That’s why having slightly bad breath in the morning is to be expected. When you smoke, practice poor oral hygiene, snore, or breathe through your mouth while sleeping, you’re more likely to have morning breath.
The sleeping disorder obstructive sleep apnea (OSA) has recently been linked to halitosis.
Watch the above video to learn more about bad morning breath and whether OSA may be causing you to wake up with bad breath in the morning.
