A dental paste filling device for filling dental paste in a container without entraining air bubbles is disclosed. The dental paste filling device includes: a paste supply stage serving as a supply source of the dental paste; a paste filling stage where the dental paste is filled in the container; and a supply flow passage connecting the both stages. The paste supply stage comprises: a storage chamber for storing the dental paste; a storage chamber depressurizing and defoaming device for depressurizing the inside of the storage chamber to defoam the dental paste within the storage chamber; and a storage chamber extruding device for extruding the dental paste within the storage chamber towards the supply flow passage. The paste filling stage comprises: a filling chamber having an open/close mechanism; a holder for detachably holding the container inside the filling chamber; a filling chamber deaerating device for depressurizing the inside of the filling chamber to prevent entrainment of air bubbles into the dental paste; and a reception port for introducing the dental paste into the filling chamber. The supply flow passage comprises: an upstream tube connected to the storage chamber; a downstream tube connected to the reception port of the filling chamber, and a discharge control valve disposed between the upstream tube and the downstream tube.
