ANATOMY

Detailed explanation-1: -Tooth enamel, unfortunately, doesn’t have the same regenerative powers. Unlike bones, teeth cannot heal themselves or grow back together if they are broken.

Detailed explanation-2: -No Cells, No Healing “Cells are what start the healing process in our bodies, and as tooth enamel consists of 90 percent minerals, there aren’t many proteins and cells there, ” explains Janne Reseland, a professor of biomaterials at the University of Oslo (UiO).

Detailed explanation-3: -Teeth are the ONLY body part that cannot repair themselves. Repairing means either regrowing what was lost or replacing it with scar tissue. Our teeth cannot do that. Our brain for example will not regrow damaged brain cells but can repair an area by laying down other scar-type tissue .

Detailed explanation-4: -The straightforward answer is no. A cracked tooth will not heal on its own. Unlike your bones, which have a lot of blood vessels, tooth enamel does not have any blood supply and is not able to repair itself when damaged. You cannot simply wait for the crack to heal on its own.

Detailed explanation-5: -It is possible for a tooth to repair itself if the damage is minimal. For example, if a tooth with a crack on the outer level and a minimal fracture line that does not cause pain may repair itself over time. The healing process is known as remineralization and refers to the minerals in our mouths.
