DD used to chew on her toothbrush with the toothpaste on it which was fine, she was probably doing a reasonable job of cleaning her teeth. For about the past month she throws the toothbrush down as soon as I give it to her and won't open her mouth for me at all. She has probably allowed me to clean them properly by opening her mouth wide about TWICE since she got her first tooth at 6 months! She now has 14 teeth and I'm getting worried that she is going to run into decay problems if this carries on. I don't want to force her and potentially run into long-term issues but what do I do?
