People in the 1800s cleaned their teeth with a combination of coarse tooth powders, stiff-bristled brushes, rags wrapped around a finger, and chewing sticks, depending on where they lived and how much money they had. The results, judging from skeletal evidence, were often poor. Most people in Western countries went through life battling heavy tartar buildup, gum disease, and tooth loss, and it was not until the second half of the century that anyone even understood why teeth decayed in the first place. Dental care in this era was a strange mix of reasonable instinct, aggressive abrasives, and outright guesswork.
The Tools of the Trade
The mass-produced toothbrush existed by 1800, but it looked nothing like a modern one. William Addis of England is generally credited with commercializing the first bristle toothbrush in the late 1700s, using bone handles drilled with holes and packed with boar bristle tufts. By the early 1800s, versions of this design were sold across Europe and North America, though they remained something of a luxury item for the first few decades. The bristles were natural animal hair, usually from hogs or horses, and they were stiff, uneven, and dried slowly, making them a friendly environment for the very bacteria they were supposed to remove.
For people who could not afford a manufactured brush or lived far from where they were sold, the standard approach was simpler: wrap a rag or piece of linen around a finger, dip it in some kind of powder or paste, and scrub. This was the dominant method for much of the population through the early and middle 1800s. Some people used small twigs with frayed ends as improvised brushes, which turned out to be surprisingly effective, as we will see. Others simply rinsed their mouths with water or salt water after meals and called it done.
Tooth Powders and Homemade Pastes
The 1800s were the golden age of tooth powder. Before toothpaste was sold in tubes starting in the 1890s, the main cleaning agent was a dry powder that you moistened with water or applied directly to a wet brush or rag. The ingredients varied enormously and were often harsh enough to strip enamel over time. Common bases included chalk (calcium carbonate), crushed charcoal, and baking soda. Some commercial powders added ground cuttlefish bone, pumice, or brick dust for extra abrasion. Flavoring came from essential oils like peppermint, cinnamon, or clove, and some recipes included honey or glycerin to make the mixture more palatable.
Homemade recipes circulated widely in household manuals and newspapers. A typical recipe might call for powdered charcoal mixed with salt and a few drops of peppermint oil. Others recommended crushed eggshells or ground sage leaves. The problem with many of these formulations was that they were too abrasive. Repeated scrubbing with gritty powders wore down tooth enamel, which paradoxically made teeth more vulnerable to decay. The people who cleaned their teeth most vigorously with these products sometimes ended up with worse dental problems than people who did less.
Commercial tooth powders became widely advertised by mid-century, with manufacturers making increasingly bold claims. Some products contained borax or other mild antiseptics, while others were little more than flavored chalk. A few contained genuinely harmful ingredients, including mercury compounds and strong acids, marketed as whitening agents. There was no regulation of dental products for most of the century, so consumers had no way to distinguish a reasonable product from a destructive one.
Chewing Sticks and Practices Beyond Europe
The boar-bristle toothbrush was a European and North American phenomenon. Across much of Africa, the Middle East, and South Asia, people cleaned their teeth with chewing sticks, a practice with roots going back thousands of years. These sticks, typically cut from trees with naturally antimicrobial properties, were chewed on one end until the fibers splayed into a brush-like tip, then used to scrub the teeth and gums. The miswak, made from the Salvadora persica tree, is the best-known example, but dozens of tree species were used across different regions.
Archaeological evidence shows that enslaved Africans brought to Brazil in the late 1700s and early 1800s had distinctive polished wear patterns on their teeth consistent with chewing-stick use, indicating they had practiced this form of oral hygiene before being enslaved.1International Journal of Osteoarchaeology. Pretos Novos: Evidence for African Oral Hygiene Practices in Brazil, 1769–1830 This is a striking piece of evidence because it shows that systematic tooth care was routine in parts of Africa long before Western-style toothbrushes arrived.
Modern research has validated some of these traditional approaches. A systematic review of traditional oral hygiene practices found that herbal dentifrices and mouthwashes containing ingredients like neem, clove, turmeric, and ginger had genuine antimicrobial properties. These traditional preparations performed about as well as fluoridated products in reducing plaque and gum inflammation.2PubMed Central. Traditional Oral Hygiene Practices and Their Effectiveness: A Systematic Review of the Evidence In other words, the 19th-century European with a boar-bristle brush and chalk powder was not necessarily better off than the person in West Africa or South Asia using a chewing stick and herbal rinse. If anything, the natural antimicrobial compounds in many traditional preparations gave them an edge that Western tooth powders lacked.
Nobody Understood Why Teeth Decayed
One of the strangest things about 19th-century dental care is that for most of the century, the fundamental cause of tooth decay was a mystery. An ancient belief that tiny “tooth worms” burrowed into enamel and caused cavities had persisted for centuries and still had adherents in the early 1800s. Other theories blamed decay on imbalances of bodily fluids or on exposure to cold air. People cleaned their teeth because dirty teeth looked bad and smelled worse, not because they understood the bacterial process that was actually destroying them.
The breakthrough came in the second half of the century, after the rise of microbiology. Willoughby Dayton Miller, an American dentist studying under Robert Koch in Berlin, worked out the relationship between oral bacteria, food residues, and tooth decay. His “chemo-parasitic” theory, published in 1890, proposed that bacteria in the mouth fermented carbohydrates and produced acids that dissolved tooth enamel. This was the first scientifically accurate explanation of how cavities form, and it was accepted widely within just a few years.3PubMed. Dental caries: from verminous to infectious disease The framework Miller described remains the foundation of how we understand caries today.
Before Miller’s work, dental hygiene advice was based on observation and guesswork. People noticed that sweet foods seemed to cause more decay, that cleaning the teeth reduced bad breath, and that some people’s teeth held up better than others. But without understanding the bacterial mechanism, there was no way to design products or routines that targeted the actual problem. Salt water rinses and certain herbal preparations happened to have mild antibacterial effects, which is why they helped, but the people using them did not know this was the reason.
What Happened When Teeth Went Bad
For most people in the 1800s, the answer to a toothache was either endurance or extraction. Professional dentistry existed but was limited in scope and accessibility. In the early part of the century, tooth-pulling was often performed by barbers, blacksmiths, or traveling practitioners rather than trained dentists. Anesthesia was not available until the 1840s, and antiseptic technique was not standard practice until even later, so having a tooth pulled was both painful and risky.
Before resorting to extraction, people tried an enormous variety of home remedies and folk cures. In Ireland during the 19th and early 20th centuries, documented toothache treatments ranged from packing the affected tooth with tobacco to herbal and mineral remedies. Some cures were more folkloric, including rituals that had no plausible medical basis whatsoever.4PubMed. Put a Frog in Your Mouth: Toothache ‘Cures’ from Nineteenth- and Twentieth-Century Ireland Clove oil, which contains eugenol, was one of the few popular remedies that actually worked as a topical pain reliever, and it is still used in some dental applications today.
Laudanum, a tincture of opium dissolved in alcohol, was widely available and commonly applied to aching teeth. It worked, in the sense that opiates dull pain, but it addressed nothing about the underlying infection and carried obvious risks of dependency. Whiskey was another common remedy, both swished around the mouth and swallowed. The overall picture is one of desperation: people reached for whatever was at hand because the pain of an abscessed tooth is genuinely excruciating, and the options for dealing with it were limited and crude.
How Bad Were 19th-Century Teeth, Really?
Bioarchaeological studies of 19th-century skeletal remains give a sobering picture. Analysis of skeletons from an immigrant cemetery in New Haven, Connecticut, found that every individual examined had heavy calculus deposits on their teeth, severe periodontal disease, and significant tooth loss that had occurred during their lifetimes. The calculus formed thick rings around the teeth, heaviest on the tongue-side surfaces where a brush or rag would have had the hardest time reaching.5PLoS ONE.

These individuals also showed linear enamel hypoplasias, which are visible lines on the teeth caused by disruptions to enamel formation during childhood, typically from malnutrition or serious illness around age three or four. This kind of evidence reminds us that dental health in the 1800s was not just about brushing habits. Nutrition played a massive role. People who grew up malnourished had structurally weaker teeth that were more prone to decay regardless of how diligently they cleaned them.
That said, it would be a mistake to assume everyone in the 1800s had terrible teeth. Diet mattered enormously, and in complex ways. At the start of the century, refined sugar was still relatively expensive and consumed in modest quantities by most people. As the century progressed and sugar became cheaper and more widely available, decay rates climbed. Populations that ate traditional diets lower in refined carbohydrates, even without access to toothbrushes, often had better dental health than urban populations eating industrialized diets. The teeth tell a story about economics and food systems as much as about brushing.
The Transformation at Century’s End
The last two decades of the 1800s brought rapid changes that began to reshape dental hygiene into something closer to what we recognize today. Miller’s discovery of the bacterial cause of decay gave tooth care a scientific foundation for the first time. Around the same period, toothpaste in collapsible tubes was introduced in the 1890s, replacing loose powders with a more convenient and standardized product. Early tube toothpastes still contained many of the same ingredients as powders, including chalk and soap, but the format encouraged more consistent use.
Nylon bristles would not replace animal hair until the late 1930s, so even the improved toothbrushes of the 1890s were still somewhat primitive by modern standards. But the cultural shift was underway. Public health campaigns began promoting tooth brushing as a daily habit rather than an occasional grooming choice. Dental schools expanded, professional standards tightened, and dentistry moved away from its roots in barbershops and market stalls toward something resembling a modern medical specialty.
Fluoride, the ingredient that would eventually do more to prevent cavities than any brushing technique, was not added to toothpaste or water supplies until the mid-20th century. So even the most conscientious tooth-brusher in 1899, armed with the best available products and the latest scientific understanding, was still missing the single most effective tool in the modern dental arsenal. The 1800s were a century of transition: people went from not understanding why their teeth rotted to having a clear scientific picture of the problem, but the full solution was still decades away.
Class, Access, and Who Got to Brush at All
Dental hygiene in the 1800s was deeply tied to social class, and the gap was enormous. Wealthy families could afford manufactured toothbrushes, imported tooth powders, and visits to trained dentists. They also tended to have better nutrition, which meant stronger teeth to begin with. At the other end of the spectrum, the poor, immigrants, the institutionalized, and enslaved people often had no access to dental care of any kind, either preventive or therapeutic. The skeletal evidence from the New Haven cemetery reflects this reality: these were immigrants whose teeth bore the marks of childhood deprivation and adult neglect.5PLoS ONE. The dead shall be raised: Multidisciplinary analysis of human skeletons reveals complexity in 19th century immigrant socioeconomic history and identity in New Haven, Connecticut
Geography mattered too. Rural populations were far less likely to encounter commercial dental products than city dwellers, but they also tended to eat less sugar. The net effect on dental health varied. A farmer chewing on a birch twig and eating mostly unprocessed food might well have better teeth at fifty than a city clerk who owned a toothbrush but consumed sugar-heavy processed foods and drank sweetened tea several times a day. The relationship between hygiene tools and actual dental outcomes was, and remains, more complicated than it appears.
Children’s dental care was largely informal. Parents might clean a small child’s teeth with a damp cloth, but dedicated children’s toothbrushes were uncommon for most of the century. Teething pain was sometimes treated with syrups containing alcohol or opiates, products like Mrs. Winslow’s Soothing Syrup that are notorious in the history of patent medicine. The idea that children’s primary teeth needed serious preventive care was slow to take hold, partly because baby teeth were viewed as temporary anyway.
Cosmetic Expectations and the Whiteness Obsession
Our modern expectation of uniformly white teeth would have seemed strange to most people in the 1800s. Teeth naturally vary in shade, and many of the popular habits of the era actively stained them. Tobacco use, extremely common among men and not rare among women, left heavy brown and yellow staining. Coffee and tea added their own discoloration. People noticed, and tooth powders were often marketed with whitening claims, but the standard of “acceptable” teeth was far more forgiving than it is today.
That said, very dark or visibly decayed teeth were considered unattractive, and there was a market for whitening treatments throughout the century. Some of these were corrosive acids that stripped surface staining along with enamel. Nitric acid and aqua fortis (another name for the same substance) were used by some practitioners to whiten teeth, with predictably destructive long-term results. The teeth would look whiter for a short time and then decay rapidly because their protective enamel had been chemically eroded. Porcelain dentures and individual false teeth were available for those who could afford them, and George Washington’s famous dental problems had already made prosthetic teeth a topic of public awareness by the early 1800s.
The desire for white teeth drove some of the more harmful products on the market, a pattern that has not entirely disappeared. The abrasive powders, acid treatments, and mercury-containing preparations of the 19th century were the ancestors of today’s over-the-counter whitening strips and charcoal toothpastes, products marketed with similar promises and, in some cases, similar risks of enamel damage if used carelessly. The cosmetic impulse has always run a few steps ahead of the science.
