    Morning breath affects most people. During the night, your mouth becomes dry and bacteria can multiply at a rapid rate  rate. Sleeping with your mouth open can increase your bad breath (halitosis). If you have been eating or drinking alcohol late the night before, these substances can still affect your breath in the morning.

    Decreased flow of saliva is a common cause of bad breath. When sleeping, saliva flow is decreased. Brushing twice a day, including in the morning, and cleaning between your teeth daily with floss can help. Brush your tongue, too.

    If you're concerned about your bad breath or experience it more frequently, consult your dentist, as it's possible there could be another cause.

    Morning breath is generally caused by a dry mouth at night. Normal salivary flow decreases at night. The bacteria in the mouth have a much better chance to grow when there is less saliva. This will lead to an increase in the likelihood of bad breath in the morning.
