    The undersigned, Alan W. Dunton, an individual, (the "Grantor") does hereby
    make, constitute and appoint Edward J. Richardson and Mark A. Catchur, and
    each of them acting individually, his true and lawful attorneys for the
    purposes hereinafter set forth, effective as of this 1st day of April, 2011.

    References in this limited power of attorney to "the Attorney" are to each
    of the persons named above and to the person or persons substituted
    hereunder pursuant to the power of substitution granted herein.

    The Grantor hereby grants to the Attorney, for the Grantor and in his name,
    place and stead, the power:

1.  To execute for and on the Grantor's behalf, in his capacity as a shareholder
    of ORAGENICS, INC., a Florida corporation (the " Company "), Schedule 13D
    and Schedule 13G, and all and any amendments thereto, in accordance with
    Section 13 of the Securities Exchange Act of 1934 and the rules and
    regulations promulgated thereunder (the " Exchange Act ");

2.  To execute for and on the Grantor's behalf, in his capacity as an officer,
    director or shareholder of the Company, Form 3, Form 4, and Form 5, and all
    and any amendments thereto, in accordance with Section 16(a) of the Exchange
    Act;

3.  To prepare, execute in the Grantor's name and on the Grantor's behalf, and
    submit to the U.S. Securities and Exchange Commission (the " SEC ") a Form
    ID, including amendments thereto, and any other documents necessary or
    appropriate to obtain codes, passwords, and passphrases enabling the
    undersigned to make electronic filings with the SEC of reports required by
    Section 13 and 16(a) of the Exchange Act or any rule or regulation of the
    SEC;

4.  To do and to perform any and all acts for and on behalf of the Grantor that
    may be necessary or desirable to complete and execute any such Schedule 13D,
    Schedule 13G, Form 3, Form 4, and Form 5 or any amendment thereto, and to
    timely file such schedule, form or amendment thereto with the SEC and any
    stock exchange or similar authority; and

5.  To take any other action of any type whatsoever that, in the opinion of the
    Attorney, may be necessary or desirable in connection with the foregoing
    grant of authority, it being understood that the documents executed by the
    Attorney pursuant to this limited power of attorney shall be in such form
    and shall contain such terms and conditions as the Attorney may approve.

    The Grantor hereby grants to the Attorney full power and authority to do and
    to perform any and every act and thing whatsoever requisite, necessary, or
    proper to be done in the exercise of any of the rights and powers herein
    granted, as fully to all intents and purposes as the Grantor might or could
    do if personally present, with full power of substitution or revocation,
    hereby ratifying and confirming all that the Attorney shall lawfully do or
    cause to be done by virtue of this limited power of attorney and the rights
    and powers herein granted. The Grantor acknowledges and agrees that neither
    the Attorney nor the Company is assuming any of the Grantor's
    responsibilities to comply with the Exchange Act.

    This limited power of attorney shall remain in full force and effect until
    the Grantor is no longer required to file any of Schedule 13D, Schedule 13G,
    Form 3, Form 4 or Form 5 with respect to his holdings of, and transactions
    in, securities of the Company, unless earlier revoked by the Grantor in a
    signed writing delivered to each of the Attorneys and any substitutes
    therefor, if any. This limited power of attorney may be filed with the SEC
    as a confirming statement of the authority granted herein.

    IN WITNESS WHEREOF, the Grantor has hereunto set his hand to this instrument
    on the date first above written.
