(Question) How should people who like coffee care for their teeth whitening?

I really like coffee..

Even when I was working at my previous company

Even 17-8 years ago, when drip coffee was not yet a big trend

I preferred brewed coffee over mixed coffee.

At this company, I used to brew coffee every morning with a coffee machine, gradually developed a refined palate by brewing pour-over coffee, and shared it with my colleagues around me...

Creating a coffee gathering like that, drinking one or two cups of coffee every day, and stopping by Starbucks in the evening to have coffee...

If you catch a cold, you can also drink decaffeinated.

As a result, my teeth are turning yellow...

I brush my teeth regularly, but I want to whiten my teeth.

Trying won't help; I can't quit coffee...

I read somewhere that brushing your teeth before drinking coffee is better for whitening.

It's not easy to go out and take a break either...

Are there any tips or things you must do for people who love coffee to whiten their teeth? I'm curious~~
