Teeth whitening

Isn't it true that almost all celebrities get laminate?

Is the goal to make the teeth appear evenly aligned?

I loved coffee so much...

As I got older over time, my teeth became discolored.

In this case, is it not necessary to go as far as laminates?

So, is teeth whitening effective?

Using products at home doesn't seem to be very effective.

If anyone has tried it at the dental clinic, please share your review.
