Laser beam , how to give more realism to

  • laser beam , how to give more realism to…

    I am designing a site for a dental clinic that offers laser whitening ;
    I sketched this idea : a laser pen gives off a red laser beam and hits the teeth of a mouth , scanning and turning them white ;
    The laser beam lacks realism ; I´ve thought something soft with blurred edged and some reflections as it hits the teeth surface ;
    I ´ve tried Soften Fill Edges on a red line converted to Fill but I don´t think the result was fine.
    Is there anything I can do in order to add more realism to the beam (and add as well some reflection to the teeth surface )?
    Thanks
