Before I go to bed, I brush my teeth and all. After I wake up, I have "morning breath." Why is this?

Question

Why and how does my breath change when I wake up? I don't eat anything while I'm asleep; at least I think I don't.

Answer 1

When you are sleeping the saliva ducts slow down the production of saliva. This means through the night your mouth will be dryer than usual.

Bad Breath: Halitosis

Complementary Medicine
Information about complementary & alternative medical therapies.

Halitosis is the technical term for bad breath, a condition estimated to affect 50 to 65% of the population. 1

Up to 90% of cases are thought to originate from sources in the mouth, including poor oral hygiene, periodontal disease, coating on the tongue, impacted food, faulty dental restorations, and throat infections. 2, 3, 4 The remaining 10% are due to systemic disorders, such as peptic ulcer (when associated with infection), 5, 6 lung infections (bad breath can be the first sign in some cases), 7 liver or kidney disease, 8, 9 diabetes mellitus, cancer, 10 or even a person's imagination (healthy individuals sometimes complain of bad breath that cannot be smelled by anyone else and is not linked to any clinical disorder). 11

In most cases, bad breath in the mouth can be traced to sulfur gases produced by bacteria in the mouth. 12, 13 Factors that support the growth of these bacteria will predispose a person to halitosis. Examples include accumulation of food within pockets around the teeth, 14 among the bumps at the back of the tongue, 15 or in small pockets in the tonsils; sloughed cells from the mouth; and diminished saliva flow. Mucus in the throat or sinuses can also serve as a breeding ground for bacteria. Conditions are most favorable for odor production during the night and between meals. 16

Although bad breath primarily represents a source of embarrassment or annoyance, research has shown that the sulfur gases most responsible for halitosis (hydrogen sulfide and methyl mercaptan) are also potentially damaging to the tissues in the mouth, and can lead to periodontitis (inflammation of the gums and ligaments supporting the teeth). 17, 18 As periodontal disease progresses, so may the halitosis, as bacteria accumulate in the pockets that form next to the teeth.

Answer 3

This is likely to be caused by reduced saliva production while you are asleep. This causes the remaining saliva to be less fresh and gives that morning breath smell! Also, protein breakdown into ketones causes this smell which is natural not just an Atkins diet symptom!

Answer 4

Couple of things.

When you brush your teeth, you also must brush your tongue to get the fur off your tongue.
Rinse your mouth with mouthwash.

Second, do not eat or drink anything 3 hours prior to going to bed.
If you do your stomach will still be processing food which produce stomach gases that are more easily move into your mouth that cause bad breath. This usually smells like sulfer.

Answer 5

Okay, you say you brush your teeth-but do you floss? do you brush your tongue? do you brush the roof and sides of your mouth?
The bacteria accumulates all night long-sleeping or not.
Oh yeah and do you sleep with your mouth open? That will definitely add to the growth of bacteria.
Go to the dentist and get your teeth cleaned/gums probed.

Answer 6

Floss, baby, floss. Once a day. Before bed is the best time if you want to prevent dragon's breath in the morning.

Answer 7

Your PH levels aer not balanced, drink 2 cups of O/J before you goto bed. You will wake up and no morning breath.

Answer 8

"Morning Breath" is caused by an accumulation of Volatile Sulfur compounds made by certain anaerobic bacteria whilst you slept. These VSC's are planted on the tongue surface where they can flourish in the collection of saliva and mucus.

Answer 9

because your mouth is the number place in your body that bacteria live. you have over 100,000 different bacteria that live in your mouth. so you cannot eliminate them with brushing, just control it from sticking to yur teeth. So they form back up at night, since you are not using your mouth. Plus your siliva also decresses, so it is not washing it away.

Answer 10

Just normal reactions with chemicals and enzymes in our bodies. When I awake, I go and use a mouth rinse every morning and feel much better.
