Eggshells are household waste which in large quantities can have a negative impact on the environment. The very high content of Calcium Carbonate 90% is the main component of the composition of egg shells. This study aims to identify the manufacture of dental biomaterials; toothpaste. The egg shell were calcinated with the sintering temperatures of 350, 500, 600, 900 0C for 10 minutes reacted with Hydroxy o- phosphate. From the spectrum results obtained, the best hydroxy apatite was at sintering temperature of 900 0C. The samples were compared to the addition of NaOH and the control variables. Additive fortification was carried out in preparations including glycerin, baking soda, and betel leaf extract for antimicrobials. Tested pH where the best at the range  4.5-10.5. From the results obtained the best is sample 10 where the pH is neutral 7 organoleptic appearance was semi solid.
