Why Do We Have Bacteria In The Mouth?
Bacteria and other microorganisms are present all over our body and inside all organs as well. This does not mean that you will get a bacterial infection. Broadly, bacteria can be put into two groups, good bacteria and bad bacteria. Not all bacteria are bad and all bacteria will not cause diseases in the body. It is the bad bacteria which upon increasing in number, which cause diseases and infections.
It is important to have a balanced quantity of good bacteria in the body for us to stay healthy. Good bacteria is especially beneficial for our gut. They keep our digestive system in good condition and also help in digestion and absorption of nutrients. Even though bacteria have a generally bad reputation as disease causing organisms, it is important to remember that our body needs a balanced quantity of good bacteria also known as probiotics.

Researchers have found over 500 species of bacteria in the human mouth. This plethora of bacterial species present in the mouth are linked with a number of oral diseases like gingivitis, periodontitis, dental plaque, teeth caries or cavities, bad breath etc.
So does this mean that because we have such a large number of bacteria in our mouth, all of us will develop some oral disease? No, this is not the case. A disease only infects the body when the body’s immunity lowers and when the count of the bad bacteria in our body increases tremendously. It is this increase in the number of bad bacteria in our body that invades our healthy organs and leads to diseases.
Bacteria are present on all the surfaces of our teeth and gums. Infact, our saliva is also full of many bacterial species.

The healthy bacteria are important to maintain the healthy microflora in the body for proper functioning of the systems. That is why you need not worry about the fact that there are bacteria in your mouth.
What Does Listerine Do?
Listerine is an antiseptic mouthwash. The first and foremost action of listerine when you rinse your mouth with it, is to flush your mouth and clean all the food debris from every nook, corner and crevice in the mouth. Flushing the food remnants makes sure that once you are finished eating or drinking, there are no food particles stuck in the mouth on the teeth or between teeth or under the gums. This ensures a clean mouth and stops the bacteria from digesting any food particles which can cause cavities and gum diseases.
As listerine is an antiseptic agent, it kills the germs in the mouth. Research has shown that Listerine mouthwash has strong bactericidal or bacteria killing properties in it and it kills upto 99.9% of the germ count in the mouth and saliva. Even at a minimum concentration, Listerine has shown excellent bacterial growth inhibiting properties, making it one of the best mouthwashes for controlling oral plaque, calculus, cavities and gum diseases.
Another important action of listerine is to form a protective layer on the enamel. The sodium fluoride content in this antiseptic mouthwash forms a protective layer on the tooth and fights cavities for as long as 24 hours.
As it has germ killing properties, Listerine keeps bad breath in check too. It keeps the breath fresh all day long and fights halitosis or bad breath. Any person who suffers from morning breath or halitosis because of any reason should use Listerine and they will surely notice a difference in the breath with continuous use.
What are the ingredients of Listerine?
Listerine mouthwash has a combination of many ingredients, each of which work together to fight cavities, gum diseases, oral germs,plaque, calculus and bad breath. Let us have a look into each of the ingredients in Listerine mouthwash and their actions.
Listerine has water, alcohol, sorbitol, sucralose, sodium benzoate, benzoic acid, sodium saccharin, and poloxamer 407 in it. In addition to these ingredients, Listerine has four essential oils in it which set this formula apart from many other commercially available mouthwashes.
These four essential oils are thymol, eucalyptol, menthol and methyl salicylate.
Each of these ingredients have their own individual actions. Water is used as the base of the mouthwash. Alcohol helps to dissolve the oils in the formula so that they can mix well with other ingredients. Also, being a disinfectant, alcohol also plays a role in killing the germs in your mouth. Sorbitol provides the sweet flavor to the mouthwash. It also acts as an hygrating agent in the formula. Similar to sorbitol, sucralose also acts as a flavoring agent and gives the mouthwash its sweet flavor.
Benzoic acid is one of the main ingredients that fights the germs. It prevents the growth and spread of the microorganisms in the mouth. Along with its anti-germ properties, it also helps to adjust the pH of the mouthwash so that it does not harm the soft tissues of the mouth. Similarly, sodium benzoate too acts as a pH maintaining ingredient in the mouthwash.
Next, sodium saccharin is another flavor enhancing ingredient in the list. All these flavor enhancing ingredients together balance each other and impart the sweet flavor to the entire mouthwash. Poloxamer 407 is responsible for flushing out all the food particles that get stuck to the surfaces of teeth and between the teeth. Just like alcohol, this ingredient also helps in mixing all the oils together to form one potent blend of all these ingredients.
The four essential oils have many important roles to play too. Eucalyptol is usually derived from trees in Australia and it has strong anti microbial activity. It acts against both bacteria and fungal growths in the mouth. Menthol gives the fresh and cooling effect after rinsing with Listerine. It also has antibacterial properties in it. Thymol also has strong evidence that suggests its germ killing properties. The fourth essential oil, methyl salicylate, is commonly found in many chewing gums. It is known for its fresh flavor and bad breath fighting properties.
