(Question) Is there a way to remove tartar from the lower teeth?

I recently visited the dentist for a check-up and scaling because I was experiencing swelling and pain near my lower teeth. After the consultation, I was told that I had periodontitis due to a significant buildup of tartar near my lower teeth, so I received scaling right away. Looking at the X-rays, it was clear that a lot of tartar had accumulated on my lower teeth, causing the gum area to be swollen. No matter how hard I brush, the tartar on my lower teeth doesn't seem to come off easily. Is there a proper brushing technique, or how to use dental floss or interdental brushes, to prevent tartar from building up on my lower teeth?
