[Concern] I want to get teeth whitening.

There is a saying that "Nureun is healthy."

I've always been envious of those with white skin since I was young.

Just as naturally changing tooth color isn't easy, it's not always easy to do it effortlessly.

I'm also worried that I might accidentally hurt my teeth.

Are there any procedures or methods that can help with teeth whitening, even if only slightly?
