Microsoft PowerPoint does not include a functionality to whiten your
teeth.
If you would like Microsoft to include such a functionality, please use
the suggestion feature.
Hi Patrick
I meant on a photograph!!! I know about the chemist, lol
how do I do this(If you would like Microsoft to include such a
functionality, please use the suggestion feature)
If you don't have something like photoshop, you can achieve something
similar (although it's not the easiest way)
insert your image into powerpoint
zoom into the teeth area
add an autoshapes > lines > freeform
carefully draw around the teeth area.
fill the autoshape with solid white, then change the 'transparency' to
approx 60 to 75% to whiten the teeth.
