Decalcified H & E stained section showing shedding of deciduous tooth
During the intraosseous phase, the rate averages 1-10 um per day, it increases to about 75 um per day once the tooth escapes from its bony cell .
Tooth eruptionKey: 1 = milk teeth; 2 = developing adult teeth; 3 = jaw bone; 4 = gum
