I brush using the
Denta Clean Tarter Control toothpaste twice (or so) a week, and then every night before bed I rub a little bit of the
Life for Teeth gel on their gums.
I started brushing Pixie's teeth as soon as I got her (around 16 weeks).
I got Charlie when he was about 7 months and as far as I can tell he's never has his brushed. It's difficult, but we're working with him....
