PRIMALS Boar Bristle & Bamboo Toothbrush (4 Pack)

I put them under warm water to soften them just what it said on the packaging and brushed my thumb through it to remove any loose bristles. It worked, the brush was soft and no bristles came loose. In my opinion the toothbrush emulsifies very well and it gentle.

Wish there was different symbols or markings to be able differentiate the brushes but theyre worth the money!

Boar bristle safe for tooth enamel long term?

I really love the no plastic option and that its fully biodegradable. I noticed the bristles are a lot harder than my old sonic brush and wonder if they will be too abrasive to enamel of teeth over time? I brush slowly and with a lighter pressure. Thoughts?
