Waking up after a long night’s sleep with a bad breath is not a nice way to start the day. However, the issue of bad breath after waking up is common, and most people experience this at one point or the other in life. The good thing is that the issue of morning breath can be treated just like every other cause of bad breath.

Bad breath which, is also called halitosis, is a popular condition that is mostly caused due to the build-up of bacteria in the mouth.

Causes of morning breath

There are quite a number of things that can cause bad breath. Some of which are;

Bad oral hygiene

One of the major causes of bad morning breath is bad oral hygiene. Failure to brush and floss regularly and properly will lead to bad breath. This is due to the accumulation of bacteria and plaques in the mouth. Not flossing regularly leaves food debris in the mouth, and as they decay, they tend to smell.

Another thing that can cause bad breath is gum disease. However, gum disease is also caused by poor and bad oral hygiene.

Dry mouth

A dry mouth means there is little saliva production in the mouth. The function of saliva is to bathe the mouth and teeth and remove all forms of food debris that have been stuck in the mouth. For a dry mouth, the food particles will remain, which will lead to bad breath as the decay of the food.

There are several things that can cause dryness in the mouth. They include:

  • Smoking

Smoking causes the mouth to dry up and can also increase the mouth’s temperature. The increase in temperature of the mouth allows the growth of the bacteria that cause the mouth to smell. These are reasons why smokers tend to have a bad mouth smell after a long night’s sleep.

  • Medications

There are some medications that can make the mouth dry. This can cause your mouth to smell bad after a long night’s sleep.

Prolonged vomiting

Dehydration can be a result of prolonged vomiting. Dehydration will make the mouth, dry and this can cause bad breath. During dehydration, the mouth will not produce enough saliva. Saliva cleans the mouth removes food debris from the mouth. This, in turn, prevents mouth odor and bad breath.

Gastroesophageal Reflux Disease (GERD)

This is a condition in which the acids in the stomach flow back into the esophagus. This can also be a cause of bad bread as this back flow of acid will aid the growth of bacteria


Allergies can also be a factor that causes bad breath. This is because the mucus that trickles down your throat is a food source for the bacteria that can cause the mouth to smell.

How to treat morning breath

Morning breathe, or bad breath can be treated using home remedies. Things that can be done to prevent the mouth from smelling bad after a long night’s sleep.


Bad breath after a long night’s sleep can be treated by having good oral hygiene. You need to not only brush regularly but also brush your teeth effectively. To brush effectively, you need to brush your teeth for about two minutes. Also, you need to brush twice daily. Many people already know the “brush your teeth two times daily,” but not everyone does this effectively. Many people do this. However, they do not do this effectively. After brushing at night, most people still munch on food before sleeping.

To get maximum effect of the brushing two times routine, you need to avoid eating anything once you have brushed your teeth at night.


Some food particles stick between the teeth and cannot be removed by ordinarily brushing the teeth. You need to floss to remove the food debris that might be stuck between your teeth and gum.

Use of mouthwash

The use of mouthwash will help to overcome bad breath. Some mouthwashes can kill the bacteria that cause bad breath. It is recommended to get mouthwashes that have this ability.

Tongue scraping

A large percentage of bad breath arises from the back of the tongue. Failure to scrap the tongue allows the growth of bacteria. These bacteria produce volatile Sulphur compounds. The Sulphur compounds include methyl mercaptan and hydrogen sulfide, which are the source of the bad breath.

To prevent the mouth from smelling bad after a long night’s sleep, it is important to have o a tongue scrapper before you sleep. Make sure you scrap your tongue forward from the back to remove the dirt.

Dry mouth product

There are several products that can help stimulate the production of saliva in the mouth. These products help to minimize the effect of dry mouth. Using this product help to increase saliva flow in the mouth and reduce the occurrence of bad breath.

Use of baking soda

Baking soda is a very common household ingredient that can be used to whiten teeth. Aside from its use as a whitening product, it can also break down and reduce plaque formation. It can also make the mouth unconducive for the growth of bacteria.

Its ability to reduce plaque formation and growth of bacteria allows baking soda to be an ingredient that can be used to combat bad breath.

To use baking soda to fight against bad breath, all you need to do is mix a teaspoon of baking soda with a cup of water. Swish the mixture in your mouth for up to a minute. Do not rinse your mouth immediately after swishing for maximum effect.


Bad breath is not something most people want to live with. Particularly waking up to a bad mouth smell after a long night’s sleep can ruin a person’s mood. To effectively treat the issue of morning breath, it is important to know the cause.

Most cases of morning breath occur as a result of bad oral hygiene. Once you can stick to a good oral hygiene routine, you can overcome morning breath.

However, if you have a good oral routine and have practiced all the remedies above but still notice that the morning breath persists, you will need to visit your dentist. The dentist will carry out a check-up and know what to do from there.
