12 Reasons For Bad Breathe (Halitosis)- A Dentist Talk

Bad breathe/Halitosis is a common problem I hear from many of my patients. Well, honestly speaking each of you might have encountered stinky breathe at some day or other. Be it after having some food foodstuff or late brushing, it can be anything. But there is nothing to feel shy of. You just need to know the right reasons behind it. 

Look, your mouth is like the storehouse of thousands of bacteria. These bacteria that live in your mouth and break down food, proteins and even skin cells, leads to the production and release of smelly volatile sulphur compounds (VSCs).

Here I am sharing some of the top causes of bad breath—and the best ways to eliminate bacteria and other halitosis culprits. 


An oral cavity with improper hygiene may be a depository of bacterium inflicting bad breathe. Keep your oral cavity clean and healthful. Improper or no brushing and flossing of teeth lead to food particles cornered in between your teeth. This can enhance a lot of microorganism growth. This further allows starches and carbohydrates to adhere to dental surfaces, providing a feast for a hungry bacterium.  Therefore, regular brushing and flossing are important. Solely then you’ll be able to cut back the odour-causing bacterium from your mouth.

Food particles not properly cleaned from appliances like braces will rot or cause bacterium and odour.  Dentures could cause sores or infections within the mouth, which might cause dangerous breath


Not drinking enough water can impair your body’s ability to produce saliva. Not only is saliva crucial for food digestion, but plaque and tartar can also more easily form when your mouth is parched. When you become dehydrated, you do not produce as much saliva. The reduced cleaning action of the saliva helps bacteria to grow. Therefore you’ll have some wonky bad breath.

Keto diet is in trend these days. Right guys? Well, the keto diet may be a low macromolecule diet that produces ketonemia. Once your body burns stored fat for fuel you will expertise “keto breath.” Several describe this breath as an argentiferous style, a fruity smell or one thing almost like nail varnish remover.


Certain foodstuffs too cause bad breathe. These are garlic, onions, dairy products, canned tuna etc. If these are your driving factors of that wonky smell. Do try to modify it and have these stuff. Moreover, there are also certain foods that act as a home remedy for bad breath.


Allergies related to the nose can cause excess mucus production in the nose as well as sinus cavities. This can lead to a nasal drip. As nasal discharge slides down through the back of the throat, it gives the oral bacteria a place to multiply, leading to a characteristic ‘bad breath’.

Many medicines are associated with bad breath, usually because they dry out the mouth. Offenders include Antihistamines, sedatives, amphetamines, antidepressants, diuretics, decongestants, anticholinergics and some antipsychotics are the real culprits. These prescription drugs cause dry mouth. Therefore, this further leads to bad breathe.


Your digestive tract is too related to your oral health. Have you ever encountered someone or you tend to have heartburn or reflux after eating certain foods? Well, that’s pretty normal. We all love spicy foods. But yes, I think dairy and spicy foods could be related to the excess acid produced by your digestive tract. Which can further lead to bad breath? Bad breath that smells fishy or has a heavy ammonia-like smell can sometimes be a sign of chronic kidney disease. Halitosis in the mouth is often attributed to common H.pylori bacteria. This bacteria not only contribute to stomach ulcers but emits a sulfuric odour too.


Coffee is both dehydrating and acidic. This is a “double whammy” when it comes to bad breath. The caffeine in coffee can just dry out your mouth by slowing saliva production. This can lead to bad breath. A lack of saliva causes bad breath for a couple of reasons.


Cigarette smoking tends to dry out the mouth and provide bacteria with a setting to thrive. Additionally, smoking will stain your teeth and place you in danger for several oral and general health problems. Smoking and tobacco chewers generally are well-known to cause poor breath and the use of tobacco leads to unhealthy gingiva as well. This could also probably contribute to bad breath.


Sweets and candies that are especially sticky tend to settle into the grooves of the biting surfaces of your teeth. This feeds the bacteria responsible for many types of bad breath issues. Bacteria thrive on sugar and because these particular sweets stick to your teeth, it can spread to all areas of the mouth including hard to reach places.


Snoring may be a major contributor to dangerous breath. Respiration through your mouth instead of your nose will dry out your mouth. Covering up breath problems with mints could briefly solve the matter, whereas the underlying cause continues to fester. If you believe that your breath is off-putting to others, schedule a medical checkup. In just minutes we can assess your oral hygiene and determine not only the cause of your bad breath but provide a care and treatment plan to eliminate it accordingly.
