08 May What Causes Morning Breath?
You roll over in the morning, your partner gives you that look, and you already know. Morning breath. We’ve all been there, and honestly, it is one of the most universal human experiences on the planet.
Morning breath is bound to happen once in a while, depending on whether or not you brushed your teeth before bed and what you had for dinner. But if it’s a persistent problem, it could be a sign of gum disease or tooth decay. So let’s get into what causes morning breath and, more importantly, what you can do about it.
So, what is the reason for morning breath?
While you’re awake, your saliva is constantly at work rinsing bacteria and food debris away. The moment you fall asleep, saliva flow drops off, and the bacteria hanging around in your mouth basically throw a party. They feed on leftover proteins and dead cells, multiplying and churning out the sulfur gases that are behind that smell you wake up to every morning.
Morning breath is a normal result of reduced saliva flow and increased bacterial activity overnight. But it’s not just bacteria. A few other things can really amplify the effect:
- Sleeping with your mouth open dries things out even faster, giving bacteria an even better environment to thrive.
- Garlic, onions, and spicy foods linger in your system long after dinner. Their compounds get absorbed into the bloodstream and eventually make their way into your lungs, meaning the smell comes from your breath itself, not just your mouth.
- Alcohol is drying, and a glass of wine at night can leave you much more parched in the morning.
- Hormonal shifts, such as those during puberty, pregnancy, or menopause, can affect the bacterial balance in the mouth as well.
Natural Remedies for Bad Breath
Looking for a few natural ways to freshen your breath? The most effective remedies for bad breath are also some of the simplest.
Here’s what you can do:
- Brush before bed, and also in the morning. Brushing before bed removes food particles and bacteria so that plaque can’t grow overnight, and brushing in the morning gets rid of any new plaque buildup and helps balance the pH of your saliva.
- Don’t forget to clean your tongue. A huge portion of the bacteria responsible for morning breath live on the surface of your tongue. A tongue scraper or the back of your toothbrush can make a noticeable difference.
- Floss nightly. Food particles caught between your teeth are prime real estate for odor-causing bacteria.
- Stay hydrated. Drinking water throughout the day helps keep your mouth clean and gets your saliva moving again.
- Skip the post-brush rinse. Whether your toothpaste has fluoride or hydroxyapatite, letting it sit on your teeth a little longer helps remineralize your enamel. Save mouthwash for after meals instead.
- Try using a Himalayan salt rinse every morning. Not only does it kill germs, it also helps soothe irritated gums.
Should I see a dentist about chronic bad breath?
Here’s where we shift gears a little, going beyond what causes morning breath and how to get rid of it.
If bad breath persists (even with good oral hygiene) or if your breath has been bothering you throughout the day and not just in the morning, it’s worth paying attention to. Chronic bad breath is often a sign of tooth decay or gum disease.
In fact, bad breath and gum disease have a well-documented relationship. There is a direct connection between gum pocket depth and a concentration of the sulfur compounds that cause bad breath. In other words, when gum disease is present, bad breath gets worse.
