Exploding Teeth in the 1800s: The Weirdest Dental Mystery in History

Reading Time: 5 minutes

Most of us have experienced a toothache at some point in our lives. Sometimes it’s caused by a cavity, sometimes by a cracked tooth, or sometimes by gum disease. Today, a quick visit to the dentist usually means the problem can be treated with a filling, root canal treatment, or crown. But in the 1800s, dental care was not as advanced. Pain relief was limited, anesthesia was not widely available, and antibiotics didn’t exist.

Among the many unusual reports from that time, one of the strangest was the phenomenon of “exploding teeth.” These rare cases were documented by dentists in the 19th century and remain one of dentistry’s greatest mysteries.

What Do We Mean by “Exploding Teeth”?

According to reports, several patients in the United States during the early and mid-1800s suffered days of agonizing toothache. Just when the pain seemed unbearable, their teeth suddenly shattered with a loud crack — sometimes described as sounding like a pistol shot. The tooth would burst into fragments, and surprisingly, the patient’s pain would disappear immediately.

This wasn’t a case of normal tooth fracture from biting into something hard, such as a popcorn kernel or ice cube. These teeth appeared to break on their own, without any outside force. Understandably, the idea of a tooth “exploding” captured the imagination of both dentists and the public.

The Most Famous Cases

The first and best-known account was written by Dr. William Henry Atkinson, a Pennsylvania dentist who later became the first president of the American Dental Association. In 1860, he published several cases in Dental Cosmos, one of the earliest American dental journals.

1817: A Reverend in Pennsylvania (identified as Reverend D.A.) had severe pain in his upper canine tooth. He was so desperate for relief that he plunged his head into cold water and even banged his head on the ground. The next morning, with no warning, his tooth burst apart with a loud crack, and the pain was gone.

1830: A woman known as Mrs. Letitia D. had a similar experience, with her toothache ending when her tooth exploded and crumbled.

1855: Another woman, Mrs. Anna P.A., described her canine tooth splitting suddenly from front to back with a “report” (meaning a sharp sound).

1871: Dentist J. Phelps Hibler reported a young woman whose molar shattered so violently that she temporarily lost her hearing in one ear.

Although only a handful of cases were documented, they were strange enough to be remembered as some of the oddest moments in dental history.

Theories About Exploding Teeth

Gas Buildup From Decay

One early theory suggested that decay inside the pulp chamber or root canal might have caused gas to build up. If the enamel and dentin are weakened, this pressure could have fractured the tooth. However, modern dentists point out that teeth are incredibly strong structures, and it’s unlikely that gas alone could create such an explosive force.

Metal Fillings and Galvanism

In the 19th century, dental fillings were made from a wide range of materials, including lead, tin, silver, and other alloys. Mercury-silver amalgam wasn’t widely standardized until the 1920s. If two different metals were used in one mouth, the saliva could act as an electrolyte, essentially turning the mouth into a small battery. This process, called galvanism, can cause electrochemical reactions. Some chemists have suggested that this might have produced hydrogen gas inside a poorly sealed cavity, leading to a sudden fracture.

Exaggeration or Miscommunication

Another possibility is that these cases were simply exaggerated tooth fractures. A severely decayed tooth can split suddenly, especially if the pulp tissue is inflamed or the enamel is already compromised. In an era before dental x-rays, patients and dentists may have described these events more dramatically than they really were.

Why Did the Explosions Stop?

Interestingly, there are no confirmed modern cases of exploding teeth. A few anecdotal reports surfaced in the 20th century, but they are considered unreliable. By the 1920s, when mercury amalgam fillings became standardized and more consistent, the reports essentially disappeared.

Why? Several reasons are possible:

Improved Filling Materials: Standardized dental amalgam and, later, composite resins reduced the risk of unusual reactions.

Better Understanding of Cavities: By the 20th century, dentists knew that caries were caused by bacteria and diet, not mysterious internal forces.

Advances in Preventive Dentistry: Fluoride, regular cleanings, and better oral hygiene have reduced the severity of untreated tooth decay.

Access to Care: More patients were able to see dentists earlier, preventing problems from escalating to the point of catastrophic fractures.

Should You Worry About Exploding Teeth Today?

The good news is no — you don’t need to worry about your teeth suddenly exploding. While teeth can crack, split, or break due to trauma, bruxism (teeth grinding), or large untreated cavities, modern dentistry prevents these problems from reaching the extreme stage described in the 1800s.

Common reasons a tooth may fracture today include:

Large cavities or untreated decay

Old, failing fillings

Night-time grinding or clenching (bruxism)

Chewing hard foods such as ice, nuts, or hard candy

Sudden trauma such as a fall, accident, or sports injury

Dentists now have many ways to treat these issues. Depending on the case, you may need a filing, inlay, onlay, dental crown, or root canal therapy. In extreme cases, extraction followed by a dental implant or bridge may be recommended.

What This Strange Story Teaches Us

The story of exploding teeth highlights just how far dentistry has come. In the 1800s, patients lived with constant dental pain, often without effective treatment. Today, modern tools like x-rays, anesthesia, and dental materials allow us to:

Diagnose problems early

Relieve pain quickly and safely

Restore teeth with strong, durable materials

Prevent serious infections that once would have caused agony

It also reminds us that oral health is closely linked to overall well-being. Toothaches may not “explode” today, but untreated decay can still lead to serious complications like abscesses, gum disease, and systemic infection.

Conclusion

Exploding teeth may sound like folklore, but a few documented cases in the 19th century show that dental mysteries were very real in an age before modern science. While we may never know for sure whether these teeth truly “exploded” or simply fractured dramatically, what we do know is that dentistry has advanced so much that such events no longer occur.

For patients today, the takeaway is simple: don’t ignore dental pain. Whether it’s sensitivity, a cracked filling, or a persistent toothache, modern dentistry offers solutions that are safe, predictable and effective. Explosions belong in history books, not in your mouth.
