Caring for useful "inhabitants" of the mouth is now in trend.
For example, Kendall Jenner created her own oral care brand, MOON. All MOON products are natural, contain oils, they not only gently cleanse, but also “create” the right environment in the mouth.
Or, for example, the English brand brushd.uk. Their dental floss is made from recycled plastic, their toothbrushes are made from bamboo, and their toothpaste is nothing like regular tube toothpaste, it comes as vegan pills in a glass jar, as one of the brand's messages is: no plastic and care for the environment.
