Halitosis: Chronic Bad Breath

Nothing can ruin a great kiss more than bad breath. There are several reasons for bad breath. If you have particularly bad breath, read on to find out more about this condition.


This is not the bad breath that is caused by eating some foods like garlic and onions. This is a severe form of bad breath. It has its origin in the gums and tongue. The reason is the same old bad dental hygiene.

Dental hygiene

Dental decay

If you do not keep your teeth clean on a regular basis, then they are bound to breed bacteria and lead to decay, which will also cause bad breath.

Gum disease

If you do not care for your gums, they will not stay all healthy and fine. Plaque will collect over them and result in a terrible mouth odour.

Overabundant anaerobic bacteria

These bacteria naturally live in our mouths. They break down the remaining food and if given the right conditions, they have a great time multiplying and producing sulphur, which has the smell of rotten eggs.

These germs are in excess because of your lifestyle or simply a natural predisposition.


If you have a lot of saliva in your mouth, it is good to wash your mouth free of bacteria. However, a lack of saliva leads to the mouth not getting enough oxygen, which leads to great conditions for the anaerobic bacteria to grow, causing bad breath. People having xerostomia have morning breath all day long.

Medical conditions


Tonsillar infections, bronchitis, pneumonia, and gastrointestinal infections can lead to halitosis.

Postnasal drip

If there is an over accumulation of mucus in the sinuses, throat and back of the tongue, it can cause the anaerobic germs to spread, causing bad breath.


Antidepressants, high blood pressure medication, anti-histamines and decongestants cause the mouth to dry up.


Diseases affecting the lungs, kidneys and liver can cause bad breath.

Other factors


Stress causes the mouth to dry and hence the problem.


Smoking encourages anaerobic bacteria and gum disease.


Alcohol does not water your mouth, it dries it up and hence the bad breath.


The best thing to do is keep good dental hygiene. Brush at least twice a day. Do not forget to floss everyday. You do not want any food to remain between the teeth.

Use a tongue cleaner as well. It will help to get rid of the bacteria that have made themselves comfortable on your tongue.

Adjust your lifestyle and drink a lot of water to keep your mouth from drying.

Instead of masking these odours, fight them and you are sure to win.

    Many people do not know the many things that cause bad breath. You have listed a lot of the main ones!
    I liked the treatments you added. many people brush their teeth twice a day, but usually fail to floss daily as well. It is very important to floss!
