Seven thousand years ago, a person with a cracked and rotting tooth had no pharmacy, no dentist, and no painkillers. Their options were limited to whatever a local healer could prepare from roots, plants, and animal fat. Dental pain is not a modern problem: cavities, abscesses, and infections have tormented humanity for tens of thousands of years, and the solutions ancient people devised ranged from surprisingly effective to deeply strange. Dental decay predates agriculture.
Researchers studying fossilized skulls over 500,000 years old have found evidence of tooth decay and wear. When humans shifted from hunting and gathering to farming around 10,000 BCE, the problem exploded. Agriculture introduced grain and refined carbohydrates, which feed mouth bacteria that produce enamel-dissolving acid. Skeletal studies show early farming populations suffered dramatically higher cavity rates than their hunter-gatherer predecessors.
In ancient Egypt, healers used botanical pastes packed directly into cavities or pressed against swollen gums. The Ebers Papyrus, dating to around 1550 BCE, contains detailed dental remedies using cumin, frankincense, and coriander berries. They also used honey, which modern science confirms has antimicrobial properties. Egyptian skulls show evidence of deliberate tooth extractions and holes drilled through jawbones to drain abscesses.
The Sumerians and Babylonians blamed toothaches on a worm, a theory that persisted for roughly 7,000 years. A Sumerian text from around 5,000 BCE describes the worm crying out to be fed, with treatment involving incantations begging gods to pull it out. Babylonian healers used henbane, a plant containing alkaloids with genuine pain-dulling properties. The toothworm theory spread to China, Greece, and Rome, and survived in European medicine until the 1700s, when microscopes revealed no worm in dental pulp.
Ancient India developed Ayurvedic oral health protocols of notable sophistication. Texts such as the Charaka Samhita and Sushruta Samhita describe oil pulling with sesame oil, a practice with mixed modern research results but possible oral hygiene benefits. Practitioners used neem twigs as toothbrushes; neem contains compounds with documented antibacterial and anti-inflammatory properties. For acute pain, they recommended clove oil, whose active compound eugenol is still used in dentistry today as a topical anesthetic.
The Greeks approached dental disease through humoral theory, attributing toothaches to phlegm settling near tooth roots. Treatments included astringent mouthwashes made from oak bark, alum, or vinegar, which have mild antibacterial properties. Hippocrates described extraction as a last resort, noting risks of infection, excessive bleeding, and death. Aristotle incorrectly believed teeth grew throughout life and that women had fewer teeth than men, misconceptions that influenced European medicine for centuries.
Roman physician Galen refined humoral dental medicine and recommended pellitory root, which contains compounds that create a numbing sensation. First-century physician Scribonius Largus described fumigation treatments where patients held their mouths over burning henbane seeds to drive out the worm. White particles that fell into the water below were hailed as the worms, though they were almost certainly seeds from the burning material. Wealthy Romans used abrasive tooth powders made from pumice, crushed oyster shells, and powdered ox hooves.
Traditional Chinese medicine understood dental pain as a disruption of qi energy, with specific teeth corresponding to organ systems. Acupuncture targeted the hegu point in the webbing between thumb and index finger; modern studies suggest this point can reduce pain perception through endorphin release. Chinese practitioners also packed arsenic paste into cavities to kill the nerve, conceptually similar to a modern root canal. Garlic, with its antimicrobial compound allicin, was widely used against infections.
Medieval Europe preserved and expanded classical texts, with monastic medicine maintaining sophisticated herbal traditions. Cloves remained a staple dental remedy, though only the wealthy could afford them. Plantain leaves, containing anti-inflammatory compounds, were chewed or pressed against swollen gums. The barber surgeon, operating with iron instruments and no anesthesia, performed extractions using tooth keys that often fractured crowns, left roots behind, or broke jaws.
Public extractions at markets and fairs sometimes included musicians playing loudly to drown out patient screams. Pre-Columbian civilizations developed their own approaches. The Maya filed teeth and inlaid them with jade and pyrite, requiring drilling technology precise enough to avoid damaging pulp. Maya healers used antiseptic tree resins and capsaicin-containing peppers that stimulate and then desensitize painful areas through the same receptor pathway modern pain creams exploit.
Aztec healers used dozens of botanicals, many later found to contain legitimate analgesic or antimicrobial compounds. Alcohol played a role across many ancient cultures, providing empirically understood sedative and pain-dulling effects. Wine-soaked wool was pressed against aching teeth, and mead, fermented honey, combined alcohol with honey’s antimicrobial properties. These treatments likely provided comfort rather than cures.
The most extraordinary cross-cultural discovery was willow bark. Ancient Egyptians, Greeks, Chinese, indigenous North American tribes, and medieval European herbalists all independently arrived at the same conclusion: chewing willow bark relieves pain. The reason is salicin, which the body metabolizes into salicylic acid, the active component of aspirin. Humanity discovered aspirin repeatedly across isolated cultures because the evidence was readily available in nature.
Skeletal studies show 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-milled grain. Dental pain was a universal condition of human existence, managed through both pharmacological and ritual approaches. Incantations and prayers addressed the psychological experience of pain alongside the physical. The earliest evidence of actual fillings comes from Slovenia, where a 6,500-year-old tooth was found packed with beeswax, which is antimicrobial and would have sealed the tooth against bacteria.
By the medieval period, Chinese dental practitioners used silver and tin amalgam fillings, while wealthy Romans used gold leaf. The impulse to preserve rather than extract decayed teeth is surprisingly ancient. Modern dentistry descends directly from these ancient discoveries. Clove oil used by dentists today has a pedigree stretching back at least 4,000 years to ancient India.
The core insight that cloves dull dental pain was figured out by someone who had never heard of eugenol and simply wanted to help a person whose tooth hurt. Ancient humans lacked modern tools but possessed the same brains, pain receptors, and refusal to suffer quietly without trying everything within reach.
