My six-year-old has a mouth full of wiggly teeth. She's still got them all, but any day now I know my daughter will accomplish another milestone. It's hard to believe she's getting so big, but I don't think I'm sentimental enough to wear a cast of her lost tooth. Le Knockout gives new meaning to the phrase "gold teeth." Believing that "the charms of youth are fleeting," designer Kim Kovel created her collection after she cast and wore her son's first fallen tooth. Mothers can capture their own children's moments with the line that includes rings, bracelets, pendants and earrings ($299 - $2,359) made in gold and pave varieties. The original tooth is returned with the commemorative piece. What's your opinion of these accessories?
