I
was wondering if anyone has tried
those new Crest tooth whitening
strips. They look fairly cool but
I don't want to invest $40 and an
hour of dorkiness a day if they
don't work. Has anyone tried them?
Is there any inconvenience involved
other than the obvious lameness
of wearing a strip for 2 periods
of 30 minutes a day? Do they actually
visually improve the whiteness of
your teeth?
