I'm curious about teeth whitening.

I was worried because I thought my teeth looked yellow.

Seeing people with pure white teeth makes me think they're so beautiful.

So, I am interested in and curious about teeth whitening.

I haven't tried teeth whitening toothpaste because I don't think it will be effective, but does it help? It seems that teeth whitening procedures are a more reliable method, but I'm curious if there are any pain or side effects.
