Which is the hardest part of the human body?

Tooth enamel is considered the hardest part of the human body. It is the outermost layer of the tooth and is composed mainly of minerals, primarily hydroxyapatite. Tooth enamel is even stronger than bone and protects the underlying dentin and dental pulp. Despite its incredible hardness, enamel can still be susceptible to damage from excessive force, acidic erosion, or poor oral hygiene. Therefore, maintaining good oral hygiene practices is crucial for preserving the integrity of tooth enamel.
