Actress Jennie Garth thinks it's important to teach kids healthy habits right from the get-go, as she likes to say.

"They are not going to learn it anywhere else," she told FoxNews.com. "So many kids are not taught about the importance of proper brushing, and they end up missing school, they have bad self-esteem, so many diseases, (which) are caused by bad oral health."

That's why Garth -  former star of the hit '90s TV show "Beverly Hills, 90210," and currently starring in her own reality TV show - has teamed up with Crest and Oral B to promote healthy teeth tips for kids.

Garth, who has three daughters - Luca, Lola and Fiona - said she got them to start brushing as young as age 2 by saying, "Oh, my gosh, there's a froggy in your teeth, I've got to get him out."

When the kids spit out the toothpaste, she'd put a little frog toy in the sink, so they'd really think there was an animal in there.
