When to start brushing babies first tooth

Natasha

Hi Everyone, my son is 7 months old and his first teeth (2 at the same time bless him!) have just broken through the gum.

Do I start brushing them now? Or wait until the 5ooth is fully there rather than just the tip?

Also any recommendations for his first toothbrush? As a parent what's the easiest to use?

Thank you all ☺️
