7 Reasons Why Your Breath Smells Bad

Reasons Why Your Breath Smells Bad

#1. Your Diet

Food is the chief perpetrator for bad breath. The chewed and broken down particles of food get stuck in the teeth, which results in increased dental plaque and bacterial growth resulting in bad breath. Strongly flavored food items like certain types of cheese, exotic spices, garlic and onions are other reasons that cause bad breath. Once the food gets digested, it enters the bloodstream and is taken to the lungs and therefore affects the breath. Some drinks like alcohol and coffee that have a strong smell can leave an aftertaste in the mouth and cause your breath to smell bad.

Diets that are low in carbohydrate may also be one of the reasons for “ketone breath.” Such diets cause the body fat to burn as the energy source. The end product of this breakdown is ketones. This results in a fruity odor in the exhaled breath. Such kind of breath in diabetics indicates high blood sugar levels.

Such kind of bad breaths are temporary and can be controlled if such food and beverages are avoided more often.

#2. Tobacco

Chewing tobacco or smoking is another reason that can cause bad breath due to residual chemicals inside the mouth. The nicotine and tar from the cigarettes are the chemicals that can stick to places like the teeth, gums, tongue and side of the cheeks resulting in bad breath. Other reasons for causing bad breath like gum diseases are worsened by tobacco and cause more bad breath.

Smoking can also cause your breath to smell bad because it dries the mouth. Smoking hinders the continuous flow of saliva and therefore the mouth does not get cleansed and hence the bad breath. This results in the multiplication of specific bacteria in the mouth resulting in constant stench in the breath. Since the saliva cannot move freely, it cannot wash away the bacteria growing in the mouth and this becomes the reason for bad breath. Besides giving bad breath, smoking also leads to cavities and yellowing of the teeth. Smoking raises the warmth in the mouth, which causes damage and also kills the tissue cells in the mouth. Thus, these tissues lose their capability of protecting the mouth effectively resulting in the free movement of bacteria across the mouth. The situation can further worsen from bad breath to give rise to grave problems related to oral hygiene.

Besides being an agent for bad breath, smoking also irritates the gums, tints the stains teeth as well as decreases the sensation of taste. Tobacco mixes the blood and flows in the system of the body, which restricts the immune system from fighting infections efficiently. The growth of blood vessels is also hindered.

#3. Dry Mouth

Xerostomia or dry mouth generally takes place when saliva production goes down. This causes trouble while speaking or a sore throat and if it continues then it becomes a reason for causing your breath to smell bad. This is because the saliva works in flushing bacteria as well as food particle remnants in and around the teeth. If this saliva dries up, then the bacteria do not get flushed out and it keeps building up. The particles are broken down by the bacteria producing a foul odor. A number of reasons lead to a dry mouth. These include antihistamines, diuretics, blood pressure, sleeping with mouth open, radiation treatments and any disease related to the salivary glands. Other reasons for dry mouth can be anxiety, depression and stress. If dry mouth is persistent and not treated at the right time, then it may also cause tooth decay, cavities, facing trouble while talking or eating and to the extent of losing teeth.

Dry mouth can be alleviated with chewing of diabetic gum, which helps in stimulating saliva without the coating of excess sugars on the teeth. Consuming lots of water and reducing caffeine as a part of the diet decreases the possibility of suffering from a dry mouth.

#4. Bad Dental Hygiene

Maintaining dental hygiene is a must for preventing bad breath. Brushing and flossing daily helps to clean up all the food particles that remain stuck in between the teeth resulting in a foul odor. Plaque is a sticky and colorless bacteria film that coats the teeth. If this plaque doesn’t get brushed away, it has the potential to cause irritation in the gums and is a reason for causing bad breath. The plaque then hardens, which is referred to as tartar or calculus. Tartar shelters the bacteria which irritates the gums and then leads to gum diseases. Gingivitis is the mild version of gum diseases. If it is not cured in time then it may lead to periodontitis. In periodontitis plaque-filled cavities are created in between the gums and the teeth. The tongue can also be inhabited by bacteria, because of its rough surface, which will eventually emit odors. Half-heartedly cleaned dentures can give refuge to food particles and bacteria that cause bad breath. Everybody should have dental checkups on a daily basis to avoid any such condition of bad breath or poor oral hygiene.

#5. Medications

A number of medications can indirectly affect the breath. Some medications can cause dry mouth giving rise to bad breath. Some other medications are further broken down by the various processes of the body, which releases chemicals. These chemicals need an outlet, which they get in the form of the mouth in bad breath. Thus, when these chemicals are carried on, they carry with themselves their foul smell. Some medications that do cause your breath to smell bad include: nitrates, tranquillizers (phenothiazines), some chemotherapy medications, antihistamines, diuretics and antidepressants.

Calcium Deficiency Causes Bad Breath in Pregnancy: Fourthly, an excess amount of calcium is required by a pregnant woman for sustaining herself and the fetus. If there is a deficiency in calcium intake, then the body uses up the calcium from the bones and teeth, which can result in bad breath.

Dietary Changes Causing Bad Breath in Pregnancy: Fifthly, the woman goes through a lot of changes when it comes to food habits and diet.
