How many times a year do you get scaling?

My gums have become much weaker since I had orthodontic treatment 15 years ago.

After getting married and moving, I adopted Sarangi, but after adopting Sarangi

My gums are deteriorating because I haven't been able to get proper care at the dentist.

They say you should get scaling every four months to delay gum recession.

I also visited other dental clinics, and they told me to come every six months.

How many times should someone with weak gums like me go for scaling?
