M.K.
I am so glad you asked this. My son who is also 6 1/2 just got his first loose tooth today. It literally happened over night. He has been telling me he had one for about 2 months now, but every time I tried to wiggle it I couldn't tell. We checked it last night & it still wasn't loose enough for me to tell. SO, today he told me he had a loose tooth & I asked him to show me & it was VERY loose. I don't think he will have it by the end of the week the way it happened, but it does always take every child different time spans to loose teeth. I think it takes longer for the tooth to come back in than it does for it to fall out. Good Luck!!!
