Brushing toddler teeth

Ka

Anyone have troubles brushing your toddlers teeth? I have a 1 1/2 year old and he refuses to let me, I even unfortunately try and hold him down to get just one tiny swipe which I know isn’t enough. I’m always so worried about his teeth because they are never brushed, he will chew on it but will refuse to let me brush them. Anyone have the same troubles and not have dental problems?
