Review on 🪥 4-Piece Soft Micro-Nano Extra Soft Bristles Toothbrush with 20,000 Bristles - Ideal for Fragile Gums in Adults, Kids, and Children (Blue, Pink) by Maria Karkhanis

I liked the concept but in practice the bristles are too dense to be effective. If they're all the same length and too close together, you're essentially rubbing your teeth with a smooth, Q-tip-like surface. So I tried brushing and brushing in the same spot and this toothbrush only cleaned the center of each tooth leaving visible food debris between the teeth or between the teeth and gums. Points of arrival intact and as expected. I understand how mild this would be for someone with severe tooth sensitivity, but even so, it's too ineffective for oral hygiene to be worthwhile.
