Brazil Boy: The human body has always been mysterious and wondrous to both scientists and laypeople. Every time science thinks we’ve understood every aspect of the body, a rare case emerges. One such startling case comes from Brazil, where an 11-year-old boy was found to have a total of 81 teeth. Yes, you read that right. Normally, an adult has 32 permanent teeth, and such a significant difference is considered quite extraordinary.

According to dental experts, even one or two extra teeth are extremely unlikely. But having three or more extra teeth is almost miraculous. According to the 2025 data from the Journal of Dentistry, the chance of this occurring ranges from approximately one in 10,000 to one in a million individuals.

Brazil Boy: What is hyperdontia and how is it recognized?

Hyperdontia means having more teeth than the normal number. These extra teeth can grow anywhere in the mouth, but they typically appear in the upper front jaw and often grow as small, pin-shaped teeth called “mesodens.”

Most people don’t know they have extra teeth until a dentist notices something unusual, such as delayed growth of permanent teeth, crowding, or abnormal spacing. Hyperdontia is accurately diagnosed through dental X-rays or 3D scans. Sometimes it can be a sign of a serious genetic condition, such as Cleidocranial Dysplasia or Gardner’s Syndrome. Therefore, dentists examine the patient by taking a complete medical history.

How useful are extra teeth and what problems do they cause?

Extra teeth are usually not useful. Experts say that these teeth are often malformed, misplaced, or completely embedded within the gums. These can push down surrounding teeth, prevent permanent teeth from erupting, and cause malocclusion. Cysts or infections can sometimes develop around them. The presence of extra teeth can also impact confidence and speech, especially in children.

In most cases, these extra teeth do not grow on their own. Removal becomes necessary only when they cause problems with the jaw.

How many extra teeth can a person have? Is the case of 81 teeth true?

Most people have only one or two extra teeth. Cases of having more than five teeth are extremely rare and often associated with a genetic syndrome. In the case of an 11-year-old Brazilian boy with 81 teeth, experts determined it wasn’t typical hyperdontia. It was a type of benign tumor called compound odontoma, a type of benign tumor composed of small tooth-like structures. The 81 extra teeth were successfully removed from the child’s jaw through surgery.

This case highlights the complexity of the human body and the limitations of medical science. Rare conditions like hyperdontia not only pose physical challenges but can also impact mental and social aspects. With timely medical examination and appropriate treatment, these problems can be resolved.
