30-120 microplastic particles shed into your mouth every time you brush, if your toothbrush has nylon bristles.
Doesn't matter if it's a manual toothbrush or sonic. Doesn't matter if you paid £1 or £150.
Boar, horsehair, charcoal, bamboo, plant based bristle brushes were meant to fix that. They have. And they haven't. Yes, they don't shed plastic.
No, they still shed. And wear down even faster. And a worn toothbrush doesn't do its job, and buying a new one every 2 weeks makes no financial sense.
