Does anyone know why we have bad breath in the morning?

Question

Just always kinda wondered but always forgot/forget to ask a dentist.

Answer 1

I'm a dentist.

Our saliva helps keep bacterial populations down. Generally, our saliva production drops significantly at night time, especially when we sleep.

The more dry your mouth, the worse your morning breath.

Ever wonder why morning breath is worse when you've been drinking the night before? Alcohol dehydrates you, which decreased salivary production even further. Additionally, alcohol contains fermentable carbohydrates for oral bacteria to consume, which increases their populations.

Answer 2

This is NORMAL. Your mouth doesn't move much by eating or drinking fluids during the night. Bacteria then accumulate to high levels. But, if after you brush, and a few hours later, the bad breath returns, you are not flossing or flossing enough BELOW and I repeat BELOW the gumline. That is where the stinky gunk is hiding! Do this over time, and no more bad breath... EVER! If you are too lazy to do this, go to the dentist and have your teeth cleaned. They will do the same and then lecture you on the above.

Answer 3

This is from Colgate Oral Care, "Some types of bad breath, such as "morning mouth," are considered to be fairly normal, and they are usually not health concerns. The "morning mouth" type of bad breath occurs because the saliva that regularly washes away decaying food and odors during the daytime diminishes at night while you sleep. Your mouth becomes dry, and dead cells adhere to your tongue and to the inside of your cheeks. Bacteria use these cells for food and expel compounds that have a foul odor."

Answer 4

There is always bacteria in your mouth... no matter how good you brush. When your sleeping, they have time to multiply which causes bad breath... not brushing properly and things like that cause more bad breath.
