The history of tooth decay shows that cavities are not a modern problem. Research has found evidence of tooth decay in human remains from more than 15,000 years ago. Early humans already experienced dental problems, even without modern sugar and processed foods.

However, cavities were much less common in ancient times. They became more widespread later as human diets changed and included more carbohydrates and sugars.

How Tooth Decay Started in Early Humans

The history of tooth decay begins in prehistoric times. Scientists have discovered cavities in ancient human teeth dating back over 15,000 years. These findings show that dental decay existed long before modern diets.

In some cases, researchers even found evidence that early humans attempted to treat cavities using primitive tools. This suggests that dental pain was already a significant problem in ancient societies.

Why Cavities Were Less Common in the Past

Although tooth decay existed, it was much less common in early human populations. Diet played a major role.

Early humans consumed natural, unprocessed foods with low sugar content. As a result, bacteria in the mouth had fewer opportunities to produce the acids that damage enamel.

Archaeological evidence shows that cavities became more frequent during the Neolithic period, when agriculture began and carbohydrate consumption increased. :contentReference[oaicite:1]{index=1}

The Role of Diet in Tooth Decay

The biggest change in the history of tooth decay came with the introduction of farming and later industrialization.

As humans began consuming more grains, sugars, and processed foods, the rate of cavities increased significantly. Tooth decay is caused by bacteria that produce acids from sugars, leading to enamel damage and cavity formation. :contentReference[oaicite:2]{index=2}

This shift explains why modern populations experience much higher rates of dental disease.

Early Attempts to Treat Cavities

The history of tooth decay also includes early forms of dental treatment. Evidence from archaeological studies shows that humans attempted to clean or modify cavities using sharp tools.

Ancient civilizations believed cavities were caused by “tooth worms.” Although incorrect, this belief highlights how common and painful dental problems were.

Over time, dentistry evolved into a scientific field, leading to modern treatments and prevention methods.

What This Means for Modern Oral Health

Understanding the history of tooth decay helps explain why cavities are so common today. Modern diets high in sugar and processed foods create the perfect conditions for bacterial growth and acid production.

Despite advances in dentistry, tooth decay remains one of the most widespread diseases worldwide.

Prevention and Modern Care

The lessons from history are clear. Diet and daily habits play a major role in oral health.

To reduce the risk of cavities:

• Limit sugar and processed foods
• Brush your teeth twice a day
• Floss daily
• Drink water regularly
• Visit your dentist for regular check-ups

According to research, understanding the causes of tooth decay is key to preventing it.

Conclusion

The history of tooth decay shows that cavities have affected humans for thousands of years. While they existed in ancient times, modern diets have significantly increased their prevalence.

Protecting your teeth today means learning from the past. Healthy habits and regular dental care can help prevent tooth decay and maintain a strong, healthy smile.

In the Moroccan cave known as Grotte des Pigeons, life was good some 15,000 years ago. The people who occupied the cave had a varied diet, fine living quarters and a close-knit community. What they didn’t have was a good tube of toothpaste — and the results, scientists have learned, were horrifying.
New research shows that the Pleistocene inhabitants of Grotte des Pigeons can lay claim to some of the worst teeth to be documented in human history. They are also the earliest known group with serious tooth decay, suffering high rates of cavities and abscesses millennia before humans invented farming. And because they were hunter-gatherers, the Grotte people subvert the conventional wisdom that it took the rise of agriculture – and the resulting carbo-loading — for cavities to become widespread.

The new study is “groundbreaking,” says Emory University’s George Armelagos, who has studied changing rates of tooth decay. “I’ve been looking at paleopathology (ancient diseases) for 50 years, and I’ve not seen anything like this before. It’s really a remarkable finding.”

During the early years of human history, dentists wouldn’t have had much business. Earlier research shows that ancient hunter-gathers had cavities in at most 14% of their teeth, and some had almost no cavities at all. Then, roughly 10,000 years ago, humans learned to farm. Grain and other carbohydrates took over the plate, making the human mouth a haven for bacteria that destroy tooth enamel. Ancient farmers had cavities in up to 48% of their teeth, leading scientists to assume that a human jaw with lots of cavities probably came from a farming society.

The people of Grotte des Pigeons — French for “Cave of the Pigeons” — tell a vastly different story. Scientists examined the remains of 52 adults who had lived between roughly 12,000 and 13,000 B.C. and were buried in the cave. An astonishing 49 of them, or 94%, had cavities, which affected more than half of the surviving teeth. Many also had dental abscesses, which cause excruciating pain. Some had lost the entire crown of a tooth, forcing the sufferer to chew on the tooth’s root.

“They have really horrible teeth,” says paleoanthropologist Louise Humphrey of London’s Natural History Museum, an author of the new study. “The only population I’ve seen with decay like that are people who lived in London about 200 years ago (and) would’ve had sugar in their diet.”

One very young adult had numerous cavities and an abscess, “almost like a textbook for dental pathology,” Armelagos says.

Making matters worse, the Grotte people deliberately yanked out the upper middle teeth of teenagers and young adults. Perhaps this was a coming-of-age ritual, or a sign of mourning, but no one knows. With age they lost their rear teeth to decay and heavy wear. So by their late 30s and 40s, “they had really very little left to eat with,” Humphrey says.

So how did the Grotte people get so many cavities without ever enjoying a cupcake or sipping a soda? By analyzing plant remains in the cave, Humphrey’s team found that residents ate lots of a particularly sweet type of acorn, which becomes soft and sticky when cooked. They also ate wild oats and legumes. Such foods can lead to serious decay, especially if the cave residents were snacking all day long, as Humphrey suspects. There’s some evidence that the Grotte people used toothpicks, but that obviously didn’t help much.

The new study, published in this week’s Proceedings of the National Academy of Sciences, shows decay-causing bacteria have been hanging around humans since before the dawn of agriculture, Humphrey says. Other scientists say the study shows bad teeth can’t always be blamed on farming.

The finding “highlights that an agricultural diet is not the only type of diet which can cause decay,” says dental science researcher Christina Adler of the University of Sydney via e-mail. But she cautions that the troubles of the Grotte people were isolated, rather than the beginning of humanity’s global battle against cavities. That battle, she says, probably began in earnest with agriculture.

The battle continues, thanks to the wide availability of sugar. If it weren’t for modern dental treatments, Humphrey says, our teeth, rather than being better than the Grotte people’s, “would probably be worse.”
