Tooth whitening in PS - is this possible?

    I am looking to use PS or some other program to preview results of tooth
    whitening in a dental office. I am trying to replicate the following
    procedure, for which specialized ($$$) programs exist:

    (1) In a picture of a smile the program/plugin/procedure should be able to
    *select the teeth area* automatically (by color or brightness - very
    different from lips, gums, etc.).
    (2) The user can then *manipulate* the color saturation, color balance on
    the selection for the desired result.
    (3) The selection can then be *combined* with the rest of the picture to be
    viewed and printed.

    Is this possible in PS - or using some plugin, procedure etc. I am a total
    PS newbie, only recently bought a digital camera :)
    I have seen past threads about manually doing this procedure.
    What I am trying to avoid is the process of manually selecting the tooth
    area, which is time consuming and imprecise.


    Thanks very much for any suggestions.

    Why go to all this trouble when you can very simple do a feathered
    selection of the teeth, turn off the marching ants with Ctrl or CMD-H
    and then do whatever you want with the tooth color.

    Thanks, I will follow this up.
    I have not even installed PS yet, let alone learned how to use it :)

    Don't discount the fact that, while tooth color is very different than
    lips & gums when we look at them, several factors incl. ambient light
    and reflections, can blur the differences to an amazing degree when
    viewing/editing digital photographs. That would be a pretty complex
    operation to be able to really accurately, automatically select and
    adjust just teeth.

    I'm afraid a manual selection using the pen tool, then convert path to
    selection, feather 2px, is the best method.

    Thanks, this is useful.
    What you suggest may very well be the case, but I have seen it done
    automatically very well by dedicated software.
    First I have to see if PS or another program has the programmability
    necessary to do it.
    Then I will tinker with the settings and see what happens.

    I'm a hobbyist, not a professsional, but I am also an actor, and anytime
    I submit a headshot, I whiten my teeth and eyes!!! :)

    As a dentist, you'd probably recommend having the color adjustment made
    directly to my teeth! :)

    Being in the industry, you are probably aware of products designed for
    just this purpose. But in my (limited) use of PS, I can't imagine an
    automation technique like what you're talking about.

    It puts me in mind of those kiosks where they take your picture and put
    it on the body of Conan the Barbarian, or a Playboy model. They have
    apparently gotten some sort of system for quick color correction of skin
    tones so that heads and bodies will match. I saw once where a black man
    had his head put on Conan's (Schwarzeneggar's) body, and with what
    appeared to be a single click, the man's face was lightened to
    (Practically) seamlessly match the skin tone of the body.

    Sorry for the rambling -

    I am not a dentist, my wife is.
    And, there is special software that allows people to visualize all sorts of
    changes without high-level computer skills.
    Such as - filling gaps, straightening teeth etc.
    They're just asking way too much for it.
    There is similar software for orthodontics, plastic surgery, even hair
    salons.
    Thanks and good luck.

    you can whiten teeth by lassoing them and feather under the select dropdown
    about 2 px then go to image drop down and select brightness and contrast.
    now to move teeth around your gonna have to go to the filter drop down and
    use the liquify filter its kind of tricky at first but does amazing work.
