Smell and taste belong to our chemical sensing system (chemosensation). The complicated process of smelling and tasting begins when molecules released by the substances around us stimulate special nerve cells in the nose, mouth, or throat. These cells transmit messages to the brain, where specific smells or tastes are identified. Olfactory (smell nerve) cells are stimulated by the odors around us, the fragrance from a rose, the smell of bread baking. These nerve cells are found in a tiny patch of tissue high up in the nose, and they connect directly to the brain. Gustatory (taste nerve) cells are clustered in the taste buds of the mouth and throat. They react to food or drink mixed with saliva. Many of the small bumps that can be seen on the tongue contain taste buds. These surface cells send taste information to nearby nerve fibers, which send messages to the brain.
Severe mouth odor is typically caused by dental infections that require treatment by a qualified dental professional. Other common causes of bad breath include diets containing certain foods, smoking and other tobacco use, poor oral hygiene, some medications, and may even result from health conditions present throughout the body.

Your dentist will often treat the cause of the problem if your bad breath is from poor oral healthcare.
Smoking is not only harmful to overall health but also contributes to bad breath from the throat. The chemicals in cigarettes can dry out the mouth, reducing saliva production and creating an environment for bacteria to thrive. Additionally, smoking can leave a lingering odor on the breath that is difficult to mask.
4. Colgate Total Advanced Pro-Shield Mouthwash: This mouthwash provides 12-hour protection against germs that cause bad breath, plaque, and gingivitis. It has a refreshing peppermint flavor and leaves your mouth feeling clean and fresh.
Gastrointestinal problems, such as constipation or bowel obstruction, can also lead to bad breath. When waste products build up in the digestive system, they can produce foul-smelling gases that are released through the mouth.
- Yogurt: Yogurt contains probiotics, which are beneficial bacteria that can help balance the oral microbiome and reduce bad breath.
While using mints or sugar-free gum can help to mask the odor, the most effective way to improve bad breath caused by tobacco products is to quit smoking or using other tobacco products. If you’re ready to quit, your dentist and hygienist can connect you to quitting resources and provide support.
Eating more frequently, small meals can help to manage weight and the effects of acid reflux. Having a large meal can upset the stomach and allow more undigested food and stomach acid to make its way into the esophagus. Additionally, maintaining a healthy weight puts less pressure on the LES.
The first thing many people do if they suspect they have bad breath is to reach for the mouthwash. The mint or clove flavouring does of course, disguise the smell for a short time, and many mouthwashes also contain antiseptic. The idea is to eliminate the bacteria that leads to foul-smelling compounds. For a time this can work. But there has been some debate concerning containing alcohol and whether it does or doesn’t exacerbate dehydration. A very dry mouth can cause breath to smell worse.
It is important to be aware of your own breath and take steps to maintain fresh breath and good oral hygiene.
Let’s get one thing straight right off the bat: no one is claiming that Listerine invented bad breath. Human mouths have stunk for millennia, and there are ancient breath freshening solutions to prove it. But, as Esther Inglis-Arkell writes at io9, in more modern days, advertisements for Listerine transformed halitosis from a bothersome personal imperfection into an embarrassing medical condition that urgently required treatment. Treatment that—conveniently—the company wanted to sell.
But it could also be more serious than that. Bad breath can be an indicator that something is seriously wrong with your health. But how can you tell the difference? Here’s a guide to some of the causes of bad breath, and how serious they might be.
Halitosis can be caused by a variety of factors. Poor oral hygiene is one of the most common causes. When we don't brush and floss regularly, bacteria build up in our mouths, leading to the production of foul-smelling gases. Gum disease, also known as periodontal disease, is another common cause of bad breath. The bacteria that cause gum disease release toxins that can contribute to halitosis.
Antiseptic mouthwashes contain ingredients such as chlorhexidine or cetylpyridinium chloride, which help reduce the amount of bacteria in the mouth. These mouthwashes can be effective in freshening breath and preventing gum disease. Fluoride mouthwashes help strengthen tooth enamel and prevent tooth decay. Cosmetic mouthwashes contain ingredients such as mint or cinnamon to temporarily mask bad breath.
Chewing gum also helps remove any food particles that may be stuck between your teeth or along the gumline. It can also help mask any odors temporarily. However, it's important to choose sugar-free gum to avoid promoting tooth decay.
3. Quit Your Bad Habits – We can’t stress enough the importance of stopping the use of tobacco products and all forms of smoking. The risks to your overall health are too high. Finally achieving fresh breath is just an added bonus.
