have I killed it with a spoon?

I was half asleep this morning and like an idiot I left a spoon in my Nutribullet cup! At first I wondered what the horrible grinding noise was but switched it off immediately noticed the rattling sound coming from the cup and discovered a teaspoon so twisted Uri Geller would be jealous. Removed the spoon and put the cup back in the bullet but the grinding noise is still there. The blades are looking a little chipped but I can see no other damage. Can I do anything to fix it?
