Bad breath or halitosis can be an embarrassing problem, particularly, when you are conversing with a friend or trying to give a kiss to your loved one. Bad breath is caused due to various reasons like dry mouth, food, tobacco products, health issues, etc.
Even unhealthy oral habits, gum diseases, diseases such as diabetes, etc., can be the reason for bad breath. Other than that, there are different reasons for a bad breath.
So what are the causes of bad breath?
Bad breath is caused because of a type of odor-producing bacteria. Therefore, you must brush and floss regularly after having food; otherwise, bacteria tend to accumulate on the food particles that are left on your mouth and in-between the teeth.
The leftover food particles in your mouth get broken down by the saliva and these bacteria grow on those food pieces. In the night, these bacteria multiply since salivary glands will be low during the night and lead to bad breath in the morning. During the bacteria’s growth, they produce sulfur compounds and this causes bad smelly breath.
Here are common reasons for a bad breath:
One of the reasons for the bad breath is dry mouth. Dry mouth is caused because of certain medications like aspirins, antidepressants, and diuretics. This condition is called as Xerostomia.
Saliva is a natural mouthwash, which acts as a moisturizer to flush away bacteria inside the mouth and tongue. When there is a reduction in saliva production in the mouth, the accumulation of bacteria increases and results in the bad mouth smell. At night, the saliva production reduces; hence, the bacterial process increases, causing a bad mouth smell in the morning.
The main reason for bad breath is because of the accumulation of the odor-releasing bacteria. They multiply and grow using the food particles inside the mouth. They release sulfur compounds during the process and can result in various gum diseases.
(3) Medical disorders
People having any underlying medical problems can produce foul smelly breaths. Chronic sinusitis and bronchitis, respiratory infections, liver ailments, diabetes, kidney diseases, any gastrointestinal disorders, throat, tonsil infections can cause you to produce fishy, stinky or fruity-smelling breath.
Food items like garlic and onions have oils and a smell-producing sulfur compound which can cause bad breath. Intake of dairy products and foods rich in protein like fish and cheeses generally produces amino-acids, which are the best nutrient sources for the bacteria inside the mouth. Beverages like tea or coffee are also known causes of bad breath. Low carb foods produce ketone smelling bad breath.
Drinking or consumption of alcohol is also the reason for bad breath. The reason is that alcohol dries up your mouth and hence, reduces saliva production.
(6) Drying of the mouth
This is the main reason for bad breath. Reduced saliva production can lead to foul-smelling breath. The decrease in saliva production is due to Xerostomia, mouth breathing, medications, or because of some issues in the salivary ducts.
People wearing braces or dentures often contain bad mouth smell because the food particles stick to the braces. And improper cleaning can cause bad smelly breath.
(8) Using tobacco products
Tobacco causes gums irritation and gum diseases. People who smoke heavily lose their sensitive taste buds. And it also causes teeth discoloration.
(9) Skipping breakfast
Having a proper breakfast helps to stimulate the saliva production. Chewing of the food helps to release saliva, which in turn, scrubs the gathered bacteria from the tongue.
(10) Breathing through the mouth
Breathing from the mouth when sleeping like snoring, asthma, etc, can dry up your mouth and increases bad breath.
