Interesting & Rare Facts about Teeth

Teeth and bones are made of calcium. But both have nerves and blood vessels. Bone marrow is made from bones. Teeth cannot form marrow. So teeth cannot be considered as bones. Here are some surprising facts about teeth that we didn’t know.

20 Unknown Facts about Teeth

1. Teeth are the hardest substances in the human body, even harder than bones.

2. Adults usually have 32 teeth, including four wisdom teeth (third molars) that typically erupt between the ages of 17 and 25.

3. Enamel, the outermost layer of the tooth, is the hardest and most mineralized tissue in the body. It helps protect teeth from decay.

4. The shape and arrangement of teeth vary among different species. Humans have a mix of incisors, canines, premolars, and molars, which serve different functions in biting, tearing, and chewing food.

5. Baby teeth, also known as primary or deciduous teeth, begin to erupt around 6 to 10 months of age. They are eventually replaced by permanent teeth.

6. Tooth enamel doesn’t contain any living cells, which means it cannot repair itself if it gets damaged or decayed. Regular dental care is essential to prevent tooth decay and maintain oral health.

7. Tooth decay, also called dental caries or cavities, is caused by the breakdown of enamel due to acids produced by bacteria in the mouth.

8. Teeth are anchored to the jawbone by roots and held in place by periodontal ligaments. These ligaments allow for a slight amount of movement, which helps absorb the forces of biting and chewing.

9. The average human spends around 38.5 days brushing their teeth throughout their lifetime.

10. The average bite force of an adult human is around 162 pounds (73 kilograms). However, some animals, like crocodiles, have incredibly strong bites that can exceed 3,700 pounds (1,700 kilograms) per square inch.

11. The sensation of tooth pain can be intense because teeth are connected to nerves and blood vessels in the dental pulp inside the tooth.

12. Tooth enamel can be discolored or stained due to various factors, including certain foods and drinks, smoking, and poor oral hygiene. Professional teeth whitening treatments can help restore a brighter smile.

13. Teeth contain unique dental records that can be used for forensic identification purposes, as the shape, size, and arrangement of teeth are highly individualized.

14. Overbrushing teeth with excessive force or using a hard-bristled toothbrush can damage enamel and gums. Dentists recommend using a soft-bristled toothbrush and brushing gently in circular motions.

15. Teeth begin to form in the womb, even before birth. By the time a baby is born, the crowns of their primary teeth are already present, hidden beneath the gums.

16. Tooth loss can lead to bone resorption in the jaw, causing changes in facial structure and potentially affecting speech and chewing ability. Dental implants can be used to replace missing teeth and maintain jawbone health.

17. The study of teeth is called odontology, and forensic odontologists can play a crucial role in identifying individuals through dental records in cases of accidents, disasters, or criminal investigations.

18. Wisdom teeth, also known as third molars, often require extraction because they may not have enough space to fully erupt or may grow at an angle, causing pain and potential complications.

19. Ancient civilizations used various methods to replace missing teeth, including dental bridges made from animal teeth, human teeth, or materials like gold and ivory.

20. Regular dental check-ups and cleanings are essential for maintaining oral health. Dentists can detect and treat dental issues early, provide preventive care, and offer advice on proper oral hygiene practices.
