Would you pay $2000 to have the slightly moved tooth fixed

I had braces and finished about 18 months ago. After the birth of my boy 5 months ago things got crazy and in the disruption I wasn’t careful so my dog ate my bottom retainer. So now one of my teeth has slightly moved.

To fix it will be another $2000 which is crazy because the whole treatment cost $10000.

Looking at the pictures, can you even tell which tooth moved? Would you pay to fix it, or just the $300 for a new retainer so that it doesn’t move any further?

Please excuse the weird photos but I didn’t now how else to take them
