(Concern) Is scaling mandatory?

Before COVID-19, I had a scaling done once a year.

However, I have never had a scaling procedure since COVID-19.

Under the current atmosphere of the COVID-19 pandemic, just going to the hospital and opening my mouth felt very burdensome.

At first, I felt really uncomfortable, but after a few years, I find it convenient and not very inconvenient at all.

I usually use Listerine after brushing my teeth, and although not every day, I also use interdental brushes.

I'm wondering if scaling is really necessary since my lifestyle habits are already well established.
Of course, depending on how it's done, there can be differences in how much management is involved, but I wonder if it's really necessary to do it as obligatorily as a health checkup.
