I'm curious about teeth whitening.

I suddenly want to get teeth whitening done at my dental clinic.

When I asked, they said there was no need to do it at the dental clinic.

They said they would take impressions at the dentist and provide whitening treatment.

How should I go home and drink with a self-serve bag?

Is this a good way to do it?

Now, whether going or returning, they say their teeth hurt a lot.

I'm worried that the skin whitening might be a little less effective.

I'm also curious if the color changes quickly.

Is it better to go directly to the dentist?
