Any way to get a cleft chin back? I used to have a slight cleft chin which has now disappeared and I'm desperate to get it back!

Hi there! I used to have a cleft chin- a small but noticeable line down the middle (like a butt chin but less pronounced!) I am now in my mid 30s and it has completely disappeared and I am desperate to get it back! It was one of my favourite features and without it my face is pretty bland. Could it just have disappeared over time or could it perhaps be due to something like weight gain on my face? I'd do anything to get it back- whether losing weight or having some kind of procedure. THANK YOU!
