(Concern) Should I get a laminate?

Hello? I am in my 40s. I usually brush my teeth on time, but I am worried because my teeth discoloration happens quickly.

I get scaling done diligently once a year. It’s okay for just a month or two, but then the discoloration comes back immediately.

I used to smoke cigarettes in the past, but I quit a long time ago.

It seems like there aren't any other actions besides coffee that negatively affect teeth whitening, but still, this happensㅠㅠ

I need to cut down on coffee, but without it, my work efficiency drops significantly, so it's really difficult.

I only drink two cups a day, should I even quit coffee for teeth whitening?
