Can phenolpthalein solution be used to prove that toothpaste is a base?

Phenolphthalein changes from colorless to pink in the range of pH 8.2 - 10. If toothpaste has a pH that is below this range, phenolphthalein will not indicate the basicity. if the pH is higher, which I believe it is in most (some) toothpastes, then phenolphthalein can be used, because it will turn from colorless to pink.

Why phenolphthalein change color?

Phenolphthalein in acidic titrations,turns colorless and pink in basic solutions.
