A Gurnee woman has a bone to pick with McDonald's.
So that's the secret ingredient!
In a lawsuit against the Waukegan franchise, the McDonald's Corporation, meat distributor OSI Industries, and Wal-Mart (where the restaurant was located), Brown says the burger she bought on July 8, 2008, caused "significant damage to her teeth."
She reportedly required a root canal, tooth extraction, bone graft, an implant tooth, dental post, and crown.
We knew burgers could wreck waistlines, but who knew your teeth were in danger too?
Brown is seeking more than $50,000 in damages, reports the Chicago Tribune.
A McDonald's spokesperson said the company is investigating the allegations.
