What brand of toothpaste is the most effective for whitening teeth? Want to be efficient

There are two kinds of whitening tooth powders that you are familiar with:

Gosmile tooth whitening agent and Bailing brand tooth powder recommended by big S.

I've used both. Let me tell you about the effect:

The taste of big S Bailing brand tooth powder is not ideal after use, and the teeth feel very astringent and uncomfortable in the mouth, especially after drinking cola, and some people will have gum pain after use, so use it with caution! As for the magical whitening effect? No, either. Gosmile tooth whitening agent is good.
