Indents on cheeks when smiling - is it swelling or filler migration overtime? (photos)

I've had cheek fillers on and off over the last 15 years but none in the last year. Over this year, I've noticed worsening indents on my upper cheek when smiling. I'm not sure if filler would help or this is from filler moving over time? Or is it swelling? I am hating how it looks in photos when I smile. I have Botox in my forehead and crow's feet every few months as well.
