Welcome to YT! There's a few threads that talk about teeth brushing, and maybe a possible video where the dog is brushing his own teeth-
Marcarter is the pups owner, she really needs to come to my area and help me with that.
The section called Health and Diet has threads about teeth. Maybe take a quick look there too.
I hope you find answers to your questions about your pup on this site. There's a ton of info here. I'm glad you made your way to us!
