Permanent teeth cutting stages in children
The eruption of permanent teeth in children is a physiological process of changing temporary milk units to permanent ones, which will never change as the child grows up. Normally, the molars begin to erupt at the age of 5-6 and continue until the age of 13, and sometimes up to 17-20, when the last third molar appears from under the gum (not always). They come out of the rudiments located under the milk units, being separated from them by a thin bone septum. Over time, the roots of milk teeth dissolve on their own and they fall out, as well as as a result of dental procedures or as a result of pushing out a germinating permanent tooth.
