Teeth growing in w/plaque

So my 6 yr old has his two bottom permanent teeth growing in with plaque.He brushes excellent,(I watch him)and uses mouthwash twice a day.So,it's not a brushing problem. He also doesn't eat sugar or drink juices with sugar.He can't go to the dentist until the end of Nov(for insurance purposes)So I was wondering if anyone else has this prob?

The same thing happened to me when I was younger. I have progressive decay and I'll probably need dentures before I'm 22.

yikes  I'm not sure that's what my son has..he just went to the dentist(right before his two teeth started growing in)and they said his teeth were fine.....I think he needs to just have is scraped off(the plaque)he has the same issue when he was a baby with his baby teeth, and they just scraped it off....but I gues the same thing is happening with his perement teeth....

does he floss? they told me to get a water pick b/c mine will get plaque quickly... it helps...and I use a scraper thing...

I'm going to buy one of those scraper things...Look like he is prone to plaque easier, soI think it would be an investment,

It helps... I have never had a cavity and have no other teeth issues, so I just use those tools, and then I will use the white strips
