I have been feeding this squirrel for about 4 years now she comes every other day to eat. I've been feeding her walnuts,pecans,grapes and peanuts. She showed up the other day and her upper teeth were gone I don't know what happened to her but now she can only eat grapes and bread. I've tried grinding up the walnuts and pecans but she won't eat it. My question is will her upper teeth grow back and if not can she survive without them? I'm really worried for her. What else can I feed her? Thank you!

Most squirrels in the wild only live a year or two. So she's had a good run. Her teeth won't grow back. Try feeding her whole grain breads and softer foods like popcorn (plain).
