My husband and I both have good teeth - he has one cavity, and I've never had one. His teeth are good due to flouride in the water where he grew up, not because of good dental hygiene (he's awful, but just lucky, I guess).
Anyway, I was brushing my 4yo's teeth tonight and noticed that there was some food stuck in her last molar. I kept brushing and it didn't come out. I took a metal pointy thing (from my high school biology kit that is similar to the tool dentists use) to try to scratch it off and it didn't come off.
So, there are a couple of very small brown spots in the crevice area of the molar (the part that is used for chewing) - they're almost too small to see. When I poked at it with the tool, they were not soft to the touch, but they are very tiny.
Is this a cavity or something else?
Her diet is not ideal - she drinks juice, eats sweets after dinner, etc, and although I think I'm a pretty good tooth brusher, DH helps her brush probably 50% of the time, and I'm sure he's not as thorough. . . .
I've read a bit about healing cavities and if this is what it is, I'd like to try xylitol and cod liver oil before going to the dentist to get it filled.
