As I said the BB teeth/splines are inlikely to have been damaged.
BB wear occurs in the bearings inside the frame.
It's not possible to judge from a picture.
Twist the shaft with your fingers, Does it feel smooth, does it bind up at all, does it have any play in it.
Even these tests are only an indication. It may be issues when actually under load.
Go look at your cranks first and determine if you are going to need to replace one or both.
It's possible the replacement cranks (if required) may require an entirely different BB. It may even come with one as a package.
