Ancient grains such as quinoa, farro, and amaranth are not just a food trend. Because they are less processed than refined grains, they digest more slowly, which means less of the rapid sugar release that feeds the bacteria behind tooth decay.
At Bagoff Dental Arts, we talk with our West Orange, NJ patients about diet almost as often as we talk about brushing and flossing, because what you eat shapes your risk for cavities and gum disease just as much as your home care routine does. Ancient grains happen to be a food trend that lines up with what dentists recommend.
Why Are Some Grains Called “Ancient”?
Unlike modern wheat, which has been crossbred for hundreds of years to bring out specific qualities such as higher yield or a particular texture, ancient grains are generally considered to be grains that have been cultivated in essentially the same form for centuries.
Not All Grains Are the Same
Grains are harvested from the seeds, or kernels, that grow on top of cereal grasses. Because they share many of the same uses and nutrients, the ancient grains category also includes pseudocereals, which are seeds and fruits from non-grasses. These seeds can be ground into flour or used whole. This distinction matters for many diet-conscious eaters because grains derived from pseudocereals are naturally gluten-free.
The Nutritional Benefits of Whole and Ancient Grains
Ancient grains are whole grains, meaning the bran, germ, and endosperm of each seed remain intact. That keeps the nutrients, protein, and fiber intact as well. Refined grains, such as white flour and white rice, have had the bran and germ removed, leaving only the endosperm, which strips away much of their nutritional value.
The Dental Benefits of Ancient Grains
Any food that offers better overall nutrition tends to be better for your teeth and gums, but whole and ancient grains offer an additional dental advantage: their more complex structure takes longer to digest.
With refined grains, digestion begins almost immediately. Saliva starts breaking food down right in your mouth while you chew, and as those carbohydrates convert to sugars, they feed the oral bacteria that produce acid as a byproduct. That acid attacks tooth enamel, softening it in ways that can eventually lead to cavities, and it also irritates gum tissue.
Refined carbohydrates tend to be stickier as well, clinging to enamel and the spaces between teeth rather than being cleared away quickly by saliva. The National Institute of Dental and Craniofacial Research notes that how often and how long sugar lingers in the mouth, not just total sugar intake, is a major factor in cavity risk, which is one more reason slower-digesting whole grains have an edge.
A Shopping List of Ancient Grains to Try
Because all ancient grains are rich in protein and fiber, each one is a solid source of these essentials, along with additional minerals, vitamins, and antioxidants. If you are ready to add a bit of history and geography to your plate, here are nine to consider.
Amaranth
Cultivated by the Aztecs, this gluten-free pseudocereal is high in manganese, magnesium, copper, and phosphorus, a mineral that helps keep enamel strong, along with vitamins B1, B6, and B9.
Barley
Grown for thousands of years across Asia and Europe, barley was one of the first cultivated grains. In its whole form, it provides selenium, manganese, copper, vitamins B1 and B3, and antioxidants. Whole barley has a tough outer shell and a longer cook time, so lightly pearled barley is a reasonable substitute with only a small loss of bran.
Buckwheat
Originating in Asia before spreading through Europe and eventually reaching early American fields, buckwheat is another pseudocereal often ground into flour. It is a good source of copper, manganese, magnesium, phosphorus, and vitamins B2 and B3, and it is naturally gluten-free.
Bulgur
A cracked wheat cereal grain common in Middle Eastern and Mediterranean cooking, bulgur adds manganese, magnesium, copper, iron, and vitamins B3 and B6 to your diet.
Farro
“Farro” refers to three different wheat varieties, each with its own cook time, texture, and flavor. First cultivated in the Middle East and Mediterranean region thousands of years ago, farro remains popular today for its nutty flavor and chewy texture, along with a helpful dose of magnesium, zinc, vitamin B3, and antioxidants.
Freekeh
Common in Middle Eastern, North African, and Mediterranean cuisine, freekeh is another form of cracked wheat, harvested while the plant is young. That gives it extra protein and fiber, along with a good source of iron.
Quinoa
Another pseudocereal, quinoa originated in South America. It is gluten-free and rich in manganese, magnesium, phosphorus, and vitamin B9. It is also a complete protein, containing all nine amino acids your body cannot produce on its own.
Spelt
One of the largest wheat crops in Europe and grown around the world, spelt has a nutty taste along with stores of manganese, copper, phosphorus, and vitamin B3.
Teff
The smallest of the ancient grains, teff is an African variety of millet, full of manganese, copper, iron, and calcium, a mineral that is vital to dental health, along with vitamins B1 and B6. Brown teff has a naturally sweet flavor.
You do not need to switch entirely to ancient grains to get the benefits of whole grains. Brown rice, whole wheat products, corn, and oats are all easy-to-find whole grains that offer many of the same advantages. Check the grain aisle at your local market for new ways to add protein, fiber, minerals, and vitamins to your recipes while cutting back on refined carbohydrates.
Pairing Whole Grains With Good Oral Hygiene
Diet is one half of the cavity-prevention equation. The other half is a consistent oral hygiene routine and regular professional care, since even the best diet cannot fully offset months of skipped brushing or overdue cleanings. Pair a whole-grain-forward diet with twice-daily brushing, daily flossing, and a routine dental checkup and cleaning to give your teeth the strongest possible defense against decay.

Frequently Asked Questions About Ancient Grains and Oral Health
Are ancient grains better for my teeth than regular grains?
Whole and ancient grains are generally better for your teeth than refined grains because they digest more slowly and release less sugar for oral bacteria to feed on. The comparison that matters most for dental health is whole grain versus refined grain, not ancient versus modern.
Do gluten-free ancient grains like quinoa help prevent cavities?
Being gluten-free does not directly prevent cavities. What helps is that pseudocereals like quinoa and amaranth are whole foods with intact fiber and nutrients, which slows digestion and reduces the sugar available to decay-causing bacteria.
Can eating more whole grains lower my risk of tooth decay?
A diet built around whole grains, vegetables, and lean protein, combined with good brushing and flossing habits, can help reduce your cavity risk over time. Diet is one factor among several, alongside home care and regular cleanings.
Are ancient grains safe to give to children?
Most ancient grains are safe for children once they are old enough for solid, textured foods, and can be a helpful source of fiber, protein, and minerals while their permanent teeth are developing. Introduce new grains gradually and watch for any food sensitivities.
How often should I have my teeth checked if I already eat a tooth-friendly diet?
Most patients benefit from a professional cleaning and exam twice a year, regardless of diet. A good diet supports your oral health between visits, but it does not replace the plaque and tartar removal, or the early detection of problems, that only a dental visit provides.
