I keep hearing people say it’s all about genetics, but honestly, I’m not totally convinced. I get that some kids are just more prone to cavities, but when I look at my own experience, habits made a huge difference. When I was a kid, my parents let me have juice in a sippy cup right before bed for years. My teeth were a mess by age six—cavities everywhere, and I ended up needing a bunch of fillings. My younger brother, same genes, but my parents got stricter with him—no drinks after brushing, and he barely had any dental issues.
Do you think maybe it’s more about consistency with those habits than pure genetics? I know some people who swear their kids have “bad teeth” no matter what, but I can’t help but wonder if little things like sneaky snacks or bedtime bottles add up over time. The sugar in milk is still sugar, even if it feels harmless, right? If it sits on the teeth all night, that’s just asking for trouble... at least from what my dentist always warned me.
I also wonder if there’s a difference between what the dentist sees and what actually happens at home. Like, maybe some kids brush better or more often, or maybe parents aren’t always catching every late-night snack. I’ve been in braces for two years now and my ortho keeps reminding me that even tiny lapses in cleaning make a big difference. Maybe it’s the same with little kids and bottles—one family’s “bad luck” could just be a few small habits piling up.
Is it possible genetics just make some kids more sensitive to the effects of those habits, rather than being the main cause? I don’t know, but from what I’ve seen with my siblings and now dealing with my own dental stuff, I’d bet habits play a bigger role than we sometimes want to admit.
I get where you’re coming from, but I’ve seen kids who brush and floss like champs and still end up with way more cavities than their siblings. Sometimes it really does seem like their enamel just isn’t as strong or their mouths are drier at night, making them more prone no matter what. Habits matter a ton, but I wouldn’t rule out genetics as a big piece of the puzzle either... it’s just hard to know which is tipping the scale sometimes.
“Sometimes it really does seem like their enamel just isn’t as strong or their mouths are drier at night, making them more prone no matter what.”
But does that mean the nighttime bottle is less of a problem if genetics are the main thing? Like, if my kid’s teeth are already weak, will taking away the bottle actually help? Or is it just trading one worry for another...
“if my kid’s teeth are already weak, will taking away the bottle actually help? Or is it just trading one worry for another...”
Honestly, I used to wonder the same thing when my niece was little. Her mom was super stressed because her own teeth had always been kind of weak, and she figured her daughter was just doomed no matter what. But here’s the thing—genetics definitely play a role, but the nighttime bottle is still a big deal. My niece ended up with a couple cavities before she was even three, and her dentist said the milk sitting on her teeth overnight was a huge factor.
Taking away the bottle won’t change their genes, but it can give those weaker teeth a fighting chance, you know? It’s not like you’re just swapping one worry for another—it’s more like taking away one of the things that could make the problem worse. The transition period is rough (I remember the crying...), but her teeth have been way better since they switched to water at night.
It’s not a magic fix, but it really does help.
I totally get where you’re coming from—my youngest had pretty soft teeth too, and I kept thinking, “Is this even worth fighting over?” But looking back, kicking the bottle at night did make a difference. Here’s kind of how it worked for us:
First, yeah, genetics are definitely part of the story, but they’re not the end of it. The sugars in milk (or juice, if anyone’s doing that) just hang out on their teeth all night, and that’s prime time for cavities to start. Even if teeth are already a bit weak, taking away that constant sugar bath can slow things down a lot.
For us, the transition was rough—lots of protests, some sleepless nights—but after a couple weeks, he stopped asking for it. We switched to water, and honestly, the dentist noticed fewer spots on his next checkup. It wasn’t a miracle, but it helped.
I used to worry I was just swapping one problem for another (like sleep issues), but honestly, the bottle at night is one thing you can control pretty easily compared to genetics. Every little bit helps, especially when you’re already working with a tougher hand.
