Bent rim, repair or replace it?

I recently bought the car and had my mechanic replace the tires and afterward he said my rim was “severely” bent. I went and checked for myself and I noticed a slight bend on the inside of the rim. I’ve been driving my car for long distances and at least 80 MPH for at least a week now and my tire still holds air and doesn’t wobble so I’m not sure if I should replace it or just leave it.
