Teeth whitening~~

Since I like coffee

Now, I feel like my teeth are stained.

A yellow light started to turn, and I began to worry.

There is no one around who has done it, so there is nowhere to ask.

I didn't even know where to look.

How long do I need to undergo teeth whitening to see results?

Is the effect not that significant?

Has anyone tried it?

Are there multiple methods for teeth whitening or just one?

Which method would be good?

How much is the cost?

It would be best to have an in-person consultation for accuracy, but I think it would be helpful to have some knowledge beforehand.
