Ancient human remains reveal that severe dental disease plagued people for hundreds of thousands of years before modern dentistry existed. Researchers examining fossilized skulls over 500,000 years old have found evidence of tooth decay, crack, and infection, proving that dental pain is far older than agriculture itself. The problem intensified dramatically around 10,000 BCE when humans shifted from hunter-gatherer lifestyles to farming. Agricultural societies introduced grain and refined carbohydrates into the diet, which fueled the bacteria in human mouths.
Studies of skeletal remains from early farming communities show significantly higher cavity rates than those found in hunter-gatherer populations, making dental pain a universal experience by the time great civilizations emerged. The ancient Egyptians developed some of the earliest recorded treatments. The Ebers Papyrus, a medical document dated to around 1550 BCE, contains detailed dental remedies. Egyptian healers packed pastes made from cumin, frankincense, and coriander berries directly into cavities or against swollen gums.
They also used honey-based compounds, which modern science confirms have antimicrobial properties that would have inhibited bacterial growth and provided some relief. Archaeological evidence shows that Egyptians performed some of the earliest extractions and drilled holes through jawbones to drain abscesses, procedures conducted without anesthesia. Mesopotamian civilizations embraced a different explanation. Sumerians and Babylonians believed toothaches were caused by a worm living inside the tooth, a theory that persisted in European medicine until the 1700s.
Babylonian healers treated the supposed worm with incantations and herbal remedies, notably henbane, which contains alkaloids with genuine painkilling properties. The toothworm theory spread to China, Greece, and Rome, and was only disproven when microscopes revealed nothing crawling in dental pulp. Ancient Indian medical texts, including the Charaka Samhita and Sushruta Samhita, describe sophisticated oral health practices. Oil pulling with sesame oil, swishing the oil through the teeth for up to 20 minutes, was a standard practice that modern studies suggest reduces certain oral bacteria.
Practitioners also used neem twigs as toothbrushes, a plant containing documented antibacterial and anti-inflammatory compounds. For acute pain, Ayurvedic healers applied clove oil directly to the tooth, a treatment that remains relevant today because eugenol, a compound in cloves, is still used as a topical anesthetic in dental procedures. Greek physicians approached dental disease through the humoral theory, believing that imbalances in the body’s four fluids caused illness. Hippocrates attributed toothaches to phlegm settling near the tooth roots and recommended astringent mouthwashes made from oak bark, alum, or vinegar, which have mild antibacterial and antiseptic properties.
He also warned that extraction carried serious risks, including infection, excessive bleeding, and death from sepsis. Aristotle contributed several errors to medical teaching, including the belief that teeth grew continuously throughout life and that women had fewer teeth than men. Ancient Rome added surgical advances and practical hygiene. Roman physician Galen recommended pellitory root, which contains compounds that create genuine numbing sensations when held against an aching tooth.
Scribonius Largus described a fumigation treatment in which patients held their mouths open over burning henbane seeds, believing the smoke would drive out worms. Wealthy Romans used tooth powders made from pumice, crushed oyster shells, and powdered ox hooves mixed with honey, functioning similarly to modern toothpaste. Some archaeological evidence points to early dental bridges secured to existing teeth with gold wire. Traditional Chinese medicine framed dental pain as a disruption in the body’s vital energy pathways, with different teeth corresponding to different organs.
Acupuncturists targeted the hegu point between the thumb and index finger, a technique modern studies suggest reduces pain perception through endorphin release. Chinese healers also packed arsenic paste into severely decayed teeth to kill the nerve, a procedure that conceptually resembles modern root canal therapy. Garlic, which contains the antimicrobial compound allicin, was widely applied to infected teeth and gums. Medieval Europe preserved classical medical knowledge alongside darker practices.
Cloves remained a staple remedy imported from Indonesia, while poorer patients used mustard seeds, pepper, and plantain, an herb containing compounds with verified anti-inflammatory and mild analgesic properties. The barber surgeon emerged as a terrifying figure who performed extractions with iron instruments, no anesthesia, and considerable force. Tooth keys, hooked devices that levered teeth against the jawbone, often fractured the crown or broke the jaw. Public extractions at markets and fairs were accompanied by musicians playing loudly, whether to distract the patient or to cover the screaming remains a matter of historical debate.
Pre-Columbian civilizations had their own approaches. The Maya drilled teeth with remarkable precision, inlaying jade and pyrite gemstones that stayed in place for thousands of years without adhesive. They drilled carefully enough to avoid damaging the pulp. For pain relief, Maya healers used antiseptic tree resins and capsaicin-containing peppers that desensitized painful areas through the same biological pathway modern capsaicin-based pain creams exploit.
Aztec healers used dozens of documented botanical treatments, many of which have since been analyzed and shown to contain legitimate analgesic or antimicrobial compounds. Alcohol played a significant role across many cultures. Wine-soaked wool was pressed against aching teeth, grain spirits were used as mouth rinses, and fermented honey, or mead, combined alcohol’s sedative effects with honey’s antimicrobial properties. None of these cured the underlying condition, but they made enduring dental pain considerably more bearable.
The most remarkable cross-cultural discovery was willow bark. Ancient Egyptians used it, Greek physicians described it, Chinese texts referenced it, Indigenous North American tribes used it, and medieval European herbalists prescribed it. Cultures that never communicated nonetheless all arrived at the same conclusion. Willow bark contains salicin, which the body metabolizes into salicylic acid, the active component of aspirin.
Humanity independently discovered aspirin over and over across civilizations because the evidence existed in nature and observant people kept noticing. Skeletal studies reveal that ancient people lived with severe chronic dental infections for years at a time, enduring marble-sized abscesses, bone loss from untreated periodontal disease, and teeth worn to the pulp by gritty stone-ground grain. People pushed through this pain while farming, fighting wars, building monuments, and writing literature. Combining ritual and pharmacology made practical sense, as managing the psychological experience of pain mattered as much as treating its physical source when the underlying problem could not be fixed.
The oldest known filling dates from Slovenia, where a 6,500-year-old tooth was found packed with beeswax. Beeswax is antimicrobial and would have sealed the tooth against bacterial infiltration while cushioning exposed dentin. By the medieval period, Chinese healers used silver and tin amalgam fillings, and wealthy Romans used gold leaf for cavity filling as far back as ancient times. The instinct to preserve rather than simply extract decayed teeth is surprisingly ancient.
Modern dentistry descends directly from these accumulated traditions. When a dentist applies clove oil before an injection, the treatment carries a pedigree of at least 4,000 years. Ancient Indian healers who never heard of eugenol discovered the core insight through observation and accumulated wisdom.
The longer history of dental pain reveals that human knowledge moves in loops, sometimes getting lost for centuries and rediscovering itself, but the drive to relieve suffering never stops.
