If it had a brush for teeth like the skin brush.
zoom into the teeth, touch up the teeth only
without changing the gum color.
Even if the current brush could be used but
instead of skin color a whitening color.
It seems that could be an easy add-on.
Add a button next to the touch up brush for teeth.
When active the brush would only be shades of white.
Not saying get rid if the teeth controls, just an add-on
