Missing filling part?

I had a this filling done in March 2023. By July it felt like there is a part missing when I fill it with my tongue. It used to be completely flat and smooth and now it feels concave like it had missed a part in the middle.
The dentist gave the photographs taken after the filling was applied in March and the one in July when I went to see him to see what happened to the filling.
The dentist is adamant everything is the same but even in the photos you can see the difference.
What do other dentists think of this.
The photo with the bigger close up is the one from March the other is July.

Might just be normal wear and tear on the filling. If the filling was a bit high, sometimes they wear down until a comfortable " level " is reached, especially after a few months of function.
I don't see anything to worry about

Thank you for your reply, I think you are probably right…although it felt like it happened overnight…
