Why do some kids barely brush and never get cavities, while others brush and still do?

Y'all see I have an interesting question. >> Go for it. >> So, here's the story. I see sometimes there are kids that they don't brush their teeth and they come to the dentist and perfect. No cavities, no issues. And then there are kids that actually brush I would say almost every single day. >> Yeah. >> But they come to the dentist and they have two, three cavities. How does it work? >> Yeah. So, first and foremost, let me just say it's genetics and it's something you really can't control. If you have good genes, you won the lottery. Some people won the lottery with khakhma, some people won the lottery good luck, some people won the lottery with their teeth. If you won the lottery khalakha kavod, you still should take care of your teeth. It should look good and feel good and smell good. But, if you didn't win the lottery and you have not such great genetics like myself with the teeth, um, you just have to be on top of it. You come every 6 months and yes, unfortunately, you may get cavities quicker. You take care of the fillings and it's a little inconvenience, little money, little time, but it's much cheaper than waiting longer and not taking care of it and then needing root canals and crowns and extractions and implants. >> So, talking about the gene, even though it's the same family, some kids have the gene. >> people have brown eyes, some people have blue eyes. There are kids, my wife almost never got a cavity and I have a mouthful of fillings. Baruch Hashem, the last 10, 15 years since I'm a dentist, I know how to take care properly, so I haven't had that many, but yes, yes, it it happens. As long as you're on top of it, great oral hygiene, careful on your diet, Baruch Hashem, stop drinking sugary sodas. It's the worst thing you can do. That's what you need to do to take care of it. >> That's right.
