A classic mouthwash is focused on removing microbes. The idea behind this is that the fewer microbes, the less sensitive the gums, the less tooth decay, the less infections and the fresher the breath.
The main ingredient to achieve the microbes’ reduction is the world-famous ethanol. Optionally, the ethanol is enriched with essential oils, such as thyme, eucalyptus, menthol, peppermint, or an aroma to reduce bad breath. You could consider a classic mouthwash as a perfume for the mouth.
Ordinary mouthwashes work instantly, but their effect, especially on bad breath, is quickly exhausted.
