Panicking about DS's tooth - how long does a cavity take to form?

[spiderlight]

DS is 6. He has been eating loads of blackberries lately, and cleaning his teeth this morning, I noticed what looks like a tiny blackberry seed wedged firmly into the fissure of one of his lower molars, towards the back of the tooth. I've tried getting it out with brushing, flossing, tape, knotted floss, a toothpick and, in desperation, a chewy sweet that I hoped it would stick to, but it isn't shifting at all and I've become increasingly paranoid as the day's gone on in case it isn't a seed at all but is in fact a cavity. We are meticulous about teeth-cleaning and DS saw the dentist at the end of July and was given the all-clear, so would it be likely that a cavity would be able to form in such a short space of time? I'm pretty sure it wasn't there at the weekend. If it's still there tomorrow I'lm going to have to make an appointment with the dentist, aren't I? I'll be gutted if it is decay :(

I suspect that this is a blackberry seed lodged that just wont budge. I have had the same in one of my back teeth and had to pick it out with a needle - probably not something you could do with a 6yo though. Try not to worry. If he was decay-free a month ago then it just isn't possible to develop a cavity in this amount of time. Also as you are so careful with teeth cleaning I suspect you limit his sugary foods and so it almost certainly not a cavity. I suspect that tomorrow morning you will look and see that it has gone.

Hope that helps.

Thanks. I'll ring the dentist to be on the safe side but DH has said the same as you and is sure it's a seed. Its so tiny I just can't tell!
