If you want to explain the claim “After 5 minutes, yellow teeth become pearly white and shiny” in detail, here is a more accurate version:
What the claim means
The statement suggests that a whitening product produces a rapid visible improvement in tooth color after approximately five minutes of use. The intended result is teeth that appear:
Whiter — yellow or stained areas appear lighter.
Brighter — the smile reflects more light and looks cleaner.
Shinier — the tooth surface appears smoother and more polished.
More pearly — the teeth have a bright, attractive white appearance.
However, “yellow to pearly white in 5 minutes” is a very strong cosmetic claim. Genuine bleaching generally requires more exposure or repeated treatments. The American Dental Association notes that peroxide-based bleaching can chemically lighten intrinsic stains, while whitening toothpastes primarily remove surface stains.

Professional in-office whitening can produce relatively rapid results, but even these treatments commonly involve 30–60 minutes of treatment rather than simply five minutes.

If you’re writing this as product advertising
A more polished and less absolute claim would be:

For best results, use exactly as directed and avoid overuse. Individual results may vary depending on the type and severity of tooth staining.
I would not advertise “guaranteed pearly white teeth in 5 minutes” unless you have clinical evidence specifically demonstrating that result for your product. Whitening can also cause temporary tooth sensitivity or gum irritation, particularly with peroxide-based products.

If you give me the product ingredients or the exact 5-minute whitening method, I can explain exactly how it could make teeth appear whiter so quickly and whether the claim is scientifically credible.
