What firmness of toothbrush bristle do you prefer?
DI prefer firm bristles, but my dentist says I have to use soft to prevent stirations on my teeth. But to me using a soft brush is about as effective as rubbing a cotton ball over my teeth. It doesn’t scrape the crud off.
I comprised and now use medium, which still isn’t as effective as a firm, but more effective than a soft.
What about you?
