Tooth development begins before birth, with baby teeth forming during the embryonic stage. They start erupting through the gums around 6 months after birth.

Children typically have 20 primary teeth, commonly known as baby teeth. As they grow, these teeth fall out to make way for permanent teeth, which number 32 in adults.

Tooth enamel is the hardest substance in the human body, even stronger than bone. It’s made up of a mineral called hydroxyapatite, which provides strength and protection to the teeth.

The inside of a tooth contains sensitive nerves and blood vessels in the pulp. When tooth decay or damage exposes these nerves, it can lead to toothaches and sensitivity.

Humans have four types of teeth — incisors, canines, premolars, and molars — each adapted for specific functions like cutting, tearing, and grinding food.

Tooth decay, a widespread chronic condition, occurs when bacterial acids erode tooth enamel over time.

Like fingerprints, dental arrangements are unique to each individual, making dental records valuable for identification purposes, similar to forensic fingerprinting.

In ancient civilizations, people used a variety of materials to clean their teeth, including crushed eggshells, charcoal, and even twigs.

Wisdom teeth, also known as third molars, typically emerge in late adolescence or early adulthood. They were historically useful for processing a rougher diet, but in modern times, they often require removal due to lack of space and potential issues.

Similar to dental arrangements, everyone has a unique tongue print, making it a potential biometric identifier.
