Morning breath is a form of bad breath, known medically as halitosis. According to the Australian government’s health information service Health Direct, bad breath is commonly the result of poor dental hygiene. In essence, morning breath is bad breath compounded by a dry mouth while sleeping.
Dry mouth is a significant contributor to morning breath. During the day, we have a steady flow of saliva which offers many protective benefits. Saliva helps destroy a variety of nasties, including bacteria and other microorganisms and helps neutralise acids produced by plaque. When you’re asleep saliva production decreases, diminishing the ability of your mouth to self-cleanse. This drying effect is especially pronounced if you breathe through your mouth
Certain types of foods can give you an unpleasant breath. For example, garlic and onions contain sulphur compounds which have a distinct odour and can cause bad breath in two ways. After eating these sulphur-rich foods, the chemicals linger on your breath for hours. To make things worse, they then enter your bloodstream where they are carried to your lungs and released through your breath.
If you fail to brush and floss properly, food particles will remain stuck in between your teeth. The bacteria in your mouth then break down these food particles, releasing a foul-smelling gas that causes bad breath.
Tobacco causes bad breath in multiple ways. Smoking tobacco reduces saliva flow, drying the mouth and making it an easy target for bacterial overgrowth. Smokers also have an increased risk of tartar buildup that can make bad breath worse by encouraging the formation of plaque on its rough surface. Plus, smoking can cause or worsen gum disease, with smokers being up to six times more likely to develop gum disease than non-smokers, according to SA Health.
Certain medications can give you a dry mouth which increases bacteria levels and makes morning breath symptoms worse.
