How many times a year do you get scaling?

I tend to experience frequent gum inflammation, so I get scaling about 2 to 3 times a year.

However, I hear a lot of people say that doing it too often around me is not good, so I asked the director, and he said it's okay.

After scaling, I feel refreshed, but I also experience a slight sensitivity, which makes me hesitant. However, since it's said to be the best method for treating gum inflammation, I can't avoid it.

Depending on your oral hygiene condition, it's okay to have scaling up to three times a year. How often do you get scaling done?
