What is Mouthwash

Mouthwash, also known as an oral rinse, is a kind of liquid used to rinse and clean the mouth. Mouthwash in general has the ability to kill bacteria in tartar, cleanse the mouth, mask bad breath caused by bacteria or yeast breaking down food residues, as well as leave a comfortable and refreshing feeling in the mouth.

More than 2000 years ago, the ancient Chinese were already aware of the importance of dental care and used various dental cleaning methods to maintain their teeth. However, due to the backwardness of science and technology and social development, the only method used to clean the mouth was “gargling”.

Along with the development of Chinese herbal medicine, ancient mouthwash has evolved from water, wine, and saltwater to herbal mouthwash. During the Qing Dynasty, people could buy a variety of herbal mouthwashes in the market.

In the late nineteenth century, dentists discovered that oral bacteria were a major cause of dental disease and in 1891, Karl August Lingner, an entrepreneur from Dresden, Germany, and Richard Seifert, a chemist, invented the world’s first mouthwash, named ‘Odol’. Mouthwash has been popular in developed countries in Europe and America for many years and may have much to do with social life etiquette. In recent years, the market has become more competitive and the number of products has increased.

How Mouthwash Work

So, how do mouthwashes clean your mouth? Early mouthwashes used eucalyptus seed oil and lemon leaf oil, both of which have antiseptic properties to improve breath. Chemical germicidal substances such as chlorhexidine were also used in mouthwashes, but these are no longer used in mainstream mouthwash brands as their overpowering germicidal properties can upset the microbial ecological balance of the mouth itself.

Olaflur, a bactericidal ingredient now widely used in mouthwashes, inhibits and kills plaque in the mouth and prevents tooth decay and periodontitis.

Generally, children’s mouthwashes use only Olaflur to kill bacteria, while adult mouthwashes add zinc chloride and linalool to Olaflur. Zinc chloride is widely used in kinds of toothpaste and mouthwashes to kill bacteria in the mouth and inhibit bad breath; linalool is both a good organic solvent and an inhibitor of Streptococcus mutans, which converts sucrose in food into glucan, the latter being a major factor in plaque formation. The latter is the main cause of dental plaque formation.

The Right Way to Use Mouthwash

It is also possible to brush your teeth before using mouthwash, as the residue on your teeth and their crevices can only be removed relatively thoroughly by a toothbrush, and it is impossible to remove the dirt completely with mouthwash alone, which is primarily a health care product.

When Should You Use Mouthwash

In the case of mouth ulcers and inflammation of the tongue, it is not advisable to use toothpaste or a toothbrush as this may aggravate your condition. However, if you have a breakout in your mouth, the use of mouthwash is likely to be accompanied by adverse manifestations such as redness and pain.

How Often Should You Use Mouthwash

After three meals, take a sip of water and rinse all parts of the mouth repeatedly to remove as much food debris and soft dirt as possible. Use up to three times a day, too much will suppress the number of bacteria in the mouth, which will affect oral health.

Should you Rinse with Water After Mouthwash

Generally, the mouthwash we use contains substances such as chlorhexidine and fluoride, which can play a role in removing oral dirt and sterilization, if you rinse your mouth with water immediately, it will affect the continuous effect of mouthwash on oral bacteria.

Some brands of mouthwash have a high alcohol content, which can reach 20% or more, and these mouthwashes can be quite irritating to use.
