What is Whitening vs. Regular Toothpaste Study about?

Diamond Gray conducted a science fair project to test whether whitening toothpaste removes more surface stains than regular toothpaste. The hypothesis was that there would be no difference. Eggs were stained in coffee then brushed with either Colgate or Crest toothpaste. Both removed 90% of stains, supporting the hypothesis that whitening toothpaste offers no additional benefit. The conclusion was that marketing claims about whitening toothpaste may be exaggerated.
