Do I need to get teeth whitening regularly?

I tend to drink a lot of coffee, green tea, and various types of tea...

It seems that staining on the teeth is unavoidable~

Even if I try not to do so... whenever I go for a regular dental check-up, I always hear about staining.

So, naturally, I started looking into teeth whitening toothpaste, teeth whitening sticks, and so on.

Suddenly, whether you get your hair done or undergo other beauty treatments, you need to do regular touch-ups.

Is teeth whitening also like that??

Is it necessary to undergo whitening regularly, as it cannot be done in just one session?
