ABSTRACT:
A method and apparatus for introducing medicinal fluids into a living body without puncturing the skin. This is done through a root canal of a tooth. A valve device is inserted in the tooth crown and connects to a reservoir of medicinal fluid in the mouth. Pressure on the reservoir will cause fluid to pass from the reservoir through the valve device and root canal into the body tissue.
