11 mo won’t let me brush her teeth. Help

Al

As the title says, I am really struggling to brush my baby’s teeth. When we first got her toothbrush, a few months ago, she used to love it and chew on it a lot. But then she suddenly stopped showing any interest in it. I’ve tried showing her with my own toothbrush, tried forcing the toothbrush in her mouth but nothing works. She either closes her mouth so tight that I can’t get it in or I miraculously manage to brush for 2 second and then she starts screaming like mad.

How do you mommies manage a situation like this? Any tips or ideas would be really appreciated

Thank you
