No cavities?!

No cavities?

im 17 and have never had a cavity. i have had about as much candy and chocolate as most people my age in my life, maybe even more. how is it possible that i still have not had any cavities?? im just curious.

the only thing i can think of is that i brush my teeth everyday, ive never skipped a day. and my uncle is my dentist, which is a tiny advantage, but still no reason why i havent got a cavity.

my teeth arent sealed

I am 26 and have had my fair share of cavities. I love sweets and eat them a lot, but I also brush daily and floss fairly often too. I do know people who never brush and have never had any cavities. I know my earliest cavity was caused by a misshaped tooth which didn't allow proper cleaning, but I think the biggest factor depends on how much and how dense the enamel on your teeth is. Just like bones, there are different shapes, thicknesses, and densities for teeth. If the enamel is thick and dense it will be strong to resist the formation of cavities. But I'm no doctor.
