Yes, you can! If a toe is missing a nail or has a damaged one, a nail technician can apply a fake toenail over it. This is typically done using acrylic or gel to create a custom nail that fits the toe perfectly. The technician would essentially sculpt a new nail, making it look natural and matching the shape and size of the other toes.
There are also adhesive fake toenail options designed specifically for this, but those might not last as long or look as realistic. The custom acrylic or gel option will be more durable and longer-lasting, though. It’s pretty common in cases of injury, nail loss, or even for cosmetic reasons if someone wants to have consistent toenail appearance.
