extortion in nj property closing

I recently sold my home in nj. During my move out, I packed the existing refrigerator and shipped it to storage. I replaced it with another refrigerator. We had a pre-closing walk-thru with the new refrigerator in place and functioning and then we closed on our home. At closing, there was no mention of the refrigerator. Now that these people own the home, they are threatening to sue for Fraud if we do not return the other refrigerator. I feel like they are trying to extort money from me after the fact. What are my leagal rights to counter sue for extortion?

Possible Malparctice by dentist

I went to dentist to fix a apparently chipped tooth. MY tongue was rubbing with it and getting hurt. This was a little pain and my life was business as usual. After gettign treatement and some filling, I has sever pain in my tongue. My dentist told me, when i was leaving his office, that i bit a my tongue very badly and there is a hole in my tognue which he already filled and treated. My life was completly disrupted for almost one complete week. After gettign some relief in pain, My original problem is as it was before visting dentist.

I am planning to sue dentist for pain, injury, waste of time and emotional demages. Does my claim has any basis?
