ABSTRACT:
A dental apparatus for applying fluid to the teeth and gums includes as one of its principle components a U-shaped flexible, rubber-like tray having side walls and a bottom wall which define a channel into which the teeth and gums can extend. Attached to the inside perimeter of the side walls near the upper edge of the tray is a flexible, elastic tube. One end of the elastic tube is sealed. The other end of the elastic tube extends through the side wall at the front of the tray and is open for connection to a source of pressurized fluid for inflating the elastic tube. Attached to the bottom wall and communicating with the channel are conduit tubes. A method using the above apparatus to apply a fluid, such as an anesthetic, to the teeth and gums is also disclosed.
