my little guy is exactly 6.5 and he lost his first tooth 2 months ago and is now working on his second loose tooth....the dentist we went to go see 2 months ago said that he was actually a little early to be losing his first tooth and she wouldn't have expected it for a few more months.....when I taught Kindergarten, I remember always having 1-2 kids who lost their teeth near the end of the K year...so I agree with Dottie...my little guy also got his teeth in early :-)
