How do I settle a claim for a dental injury at a restaurant?

You hopefully have the actual screw that you bit in to. Or, took a photograph of the screw.  And, if you were other people that were witnesses to corroborate your event.  The value of your claim depends on many factors.  You will need to keep the dental bills and any photographic evidence from your injury.  You also need to make sure you know the exact date that this occurred.  The value of your claim could be worth more than just the cost of the crown.   Any type of documentation you have would be helpful for an attorney to advise you on.  They will need to know the exact location and the county in Texas that you were injured.  If you have the names of the manager and/or other personnel from the store, that would be of help too when you discuss the claim with an attorney.   I would encourage you to call an attorney and talk directly with someone who does this type of legal work. Most of us charge nothing to talk to prospective clients in this area of legal work.
