Budgie Squashed Toe

Around a month ago Silva got her toe caught in the door. It was bleeding but not dripping and eventually a scab formed. After applying antiseptic for a week the scratch healed completely. However even a month later the toe still looks slightly flatter compared to her other foot although it doesn't look like she is in any pain/discomfort. Is there any way to help get the toe back to normal, will it heal on its own or is it permanent?
