Calcium. We regularly hear how important calcium is for our kids’ diets. It’s vital for healthy growth. Calcium is a building block for strong bones. It helps with hormone balance and keeps the heart pumping and blood circulating normally. But, did you know that calcium is also vital for healthy teeth?
Calcium builds strong bones. Years of milk commercials (backed by years of research) have firmly planted that information in our brains. In fact, 99% of the calcium in the body goes to building healthy bones and teeth. Calcium is the hard mineral that makes bones hard, and it also makes the enamel that surrounds our teeth the hardest substance in the human body.
Since 99% of the calcium in the body is in the teeth and bones, you might think there’s always enough for the teeth, but it turns out that’s not always the case. Because regulating heart rhythms and hormone balance is necessary to stay alive, if there isn’t enough calcium for these vital functions from food, the body will take it from anywhere it can get it.
Unfortunately, that means your body and your kids’ bodies will take calcium from the teeth and bones to keep enough of it for other necessary jobs it has in the body. Teeth without enough calcium can develop demineralized spots, dull white spots on the teeth that are not as strong as regular enamel. Those spots are fragile and have a high risk of turning into full cavities.
Not having enough calcium in your diet may not sound as scary as the big bad wolf, but it’s far more worrisome in real life. More than half of both boys and girls 9-13 routinely get less than half of the calcium required for good health at their age. The National Institutes of Health identifies several groups that are chronically at risk of inadequate calcium. They include girls 4 and older, especially adolescent girls, and boys age 9-18. Women who are pregnant also need additional calcium to support bone development in the growing baby.
When we say calcium, we often flash back to those milk ads. It’s true; there is a lot of calcium in dairy. That includes milk, yogurt, and cheese. But, not all calcium-rich foods are dairy based, which is good news for those who cannot or will not eat dairy.
Sardines pack more calcium per 3-ounce serving than calcium-fortified orange juice, but the orange juice will probably be easier to convince your children of. Dark green leafy vegetables like kale, bok choi, Chinese cabbage, and turnip greens also pack a calcium punch. Even a corn tortilla can provide 5% of the recommended daily value of calcium.
Calcium supplements are commonly used to make up for a lack of calcium in the diet. They can be a good choice to help when there is no way to make up the calcium by better eating, but they require a little extra care. Food-sourced calcium is easier for the body to process. Calcium carbonate is less expensive, but harder to absorb and can be hard on people with stomach issues. Calcium citrate is easier to absorb, but is more expensive and can be harder to find.
Sometimes with supplements, you can run into “a little is good, more is better” mentality. That’s just not the case. There’s an upper limit to how much calcium your body can safely process in a day. The smaller the body, the smaller the limit. While it’s very unlikely that you would exceed that limit with food alone in your children’s diets, supplements, particularly gummy ones with candy flavors, can increase the risk of having too much. As with most things in life, balance is key.
With some care and attention, it’s possible to keep your family healthy and calcium rich, making your dental visits more pleasant. If supplements are necessary, they are readily available. Healthy calcium builds healthy teeth, so build healthy eating habits and keep your teeth ready to eat with you (and your family) for a lifetime.
