Do i need to Sue?

Based on the facts that you shared, it is possible that you have a claim to assert on an individual basis, rather than as a class action, with regard to the injuries that you sustained from a defective product. You should consult with an attorney in your area about how best to proceed.

As the other poster said, your best bet is to consult with a local personal injury attorney. We don't have all the facts of your case, but there will most certainly be some issues that arise. Did you keep the candy that chipped your tooth? Did you receive treatment at the ER? Do you have a receipt to show that you purchased the candy? These are likely some of the questions that any attorney you see will bring up. As an aside, the other poster is correct, this wouldn't be a class action suit. If you move forward, it'll just be an individual suit against the candy company.

Your ability to prove your claim depends on whether you kept the defective candy or not. If it's in the box, freeze it immediately. Put it in double zip lock bags to keep it as fresh as possible. The claim is for a non-food product in a box of food. That's a claim against the manufacturer, not WalMart. WalMart doesn't have anything to do with what's inside the box. Get yourself to a lawyer who knows about product liability cases as soon as possible. That's probably going to be someone in either Fargo or Bismarck since North Dakota's a very rural state. Good luck!
