Brush your kid’s teeth the old way

I keep seeing this ultrasonic electric toothbrush sprout up. It bills itself as an easier way to clean your kid’s teeth without the emotional headaches. But glancing at the reviews, it’s clear this isn’t an alternative to regular brushing. Everyone knows that a right of passage in parenting is prying a toddler’s mouth open so you can get to those back molars. You can’t cut corners when brushing your teeth!
