FOR IMMEDIATE RELEASE

              ORAGENICS, INC. TO DE-LIST FROM TSX VENTURE EXCHANGE

ALACHUA, FL (October 7, 2004) - Oragenics, Inc. (AMEX:ONI; TSX-V:ORA.U) today
announced that effective on October 13, 2004, the Company will de-list from the
TSX Venture Exchange and trade exclusively on the American Stock Exchange
("AMEX") under the symbol "ONI..

Oragenics, Inc. has been listed on the TSX Venture Exchange (symbol "ORA.U")
since June 24, 2003, when the Company completed an initial public offering of
its common stock. On May 20, 2004, Oragenics, Inc. stock began trading on the
American Stock Exchange (symbol "ONI"). Since that time, the volume of
Oragenics' shares being traded on the TSX Venture Exchange has steadily
declined. Oragenics shares will continue to be traded on the American Stock
Exchange under the symbol "ONI."

"We appreciate the opportunity of having our stock traded on the TSX Venture
Exchange," said Chuck Soponis, Oragenics chief executive officer. "The TSX
market provided excellent support for our shares and the staff at the venture
exchange has been consistently helpful and cooperative. However, we believe that
a sole listing on the AMEX will diminish investor confusion, reduce our filing
costs, and provide a satisfactory alternative for our Canadian investors."
