'dimple' tweeter fix

The question I had was once you're able to pop it back is the tweeter damaged even though visually the tweeter looks ok
Are sonics effected once the tweeter is pushed in

You won't know until you listen to the popped back tweeter (driver).

Once a soft dome is deformed with a crease, it no longer behaves the same way under operation. What likely occurs are deviations from the original frequency response above 7000Hz where the dome typically starts entering resonance modes. The deformations and creases that might be in the dome now will alter those modes and change the way the tweeter radiates.

If you can quickly correct a poked in dome so that there are no creases, you stand a better chance at an unaffected speaker. If it hasn't been corrected for a length of time and creases permanently establish themselves, your best bet is to replace the dome assembly, which in the case of Dynaudio, an expensive proposition.

My buddy's tweeter was pushed in and then immediately came out on it's own there is still a crease but not sure if any damage was done
I think these things are really delicate

He's debating whether to change his tweeter as a result

What do you guys think ?

Listen and then decide.
