The crown of the tooth is covered by<u> the enamel</u>, the hardest substance in the body.
The hardest material in the human body is dental enamel, or the hard tissue that covers the outside of the tooth crown.
It is more mineralized and durable than bone and the most heavily mineralized bodily tissue.
Calcium phosphate, a hard mineral, makes up the majority of it.
Dentin is the layer that lies behind your enamel. It is created from mineral-secreting live cells. The pulp, the primary living component of the tooth, is located underneath the dentin.
Dental crowns are caps that are affixed to broken teeth.
When fillings are ineffective, crowns are utilized to preserve, cover, and restore the contour of your teeth.
Metals, porcelain, resin, and ceramics can all be used to create dental crowns.
