When should I start brushing baby’s teeth?

Thank you!!! At what age is this?

This baby is 9 months

The video shows something different than the title suggests. My daughter is 3,5 months but already has 2 bottom front teeth showing. I did already buy this finger brush, but when should I actually start brushing? When they've fully protruded or as soon as they are showing?

​@@Snerpderp when they came out. No need before that.
