🦷 81 Teeth in One Mouth — The Rarest Dental Case Ever Recorded
In a remarkable dental case from Brazil, doctors discovered an 11-year-old girl with 81 teeth — the highest number ever documented in a single human mouth. This condition, known as multiple hyperdontia, occurs when extra (supernumerary) teeth develop beyond the normal count. Most people with hyperdontia have one or two extra teeth — but 31 additional teeth is almost unheard of.
Surprisingly, this young patient showed no underlying syndrome or genetic disorder, making the case a medical mystery. Each extra tooth varied in shape and size, causing crowding, jaw deformity, and difficulty in normal chewing and speech.
Managing such a complex case requires a team of oral surgeons, orthodontists, and prosthodontists, often involving staged extractions, growth monitoring, and reconstructive planning over several years.
This rare condition underscores the importance of routine dental check-ups in children. Early panoramic X-rays can detect hidden extra teeth before they disrupt normal eruption or alignment. Parents should watch for delayed tooth eruption, unusual spacing, or facial asymmetry — subtle signs that may hint at an underlying anomaly.
