My nail cuticles are in bad shape, I need help?

I dont so much bite my nails, but bite them to keep them in shape, they are fairly long.





I do however have the bad habit of bitting the skin around the sides of my nails.





Problem is this has pushed back my cuticles a bit further then what I would like, so it makes my fingers and nails look stubbier then they are.





If I just stop my nail biting in general will my cuticles restore themselves?My nail cuticles are in bad shape, I need help?
