After my wisdom tooth was removed, my face became paralyzed for a couple days. Is this a dental error that calls for a lawsuit?

You may have a claim against the oral surgeon.  You should begin by seeing an attorney that specializes in dental or medical malpractice.  He or she will likely send you to a specialist to determine what exactly happened and whether the surgeon was at fault.  The paperwork you signed before the surgery took place will also be reviewed.  Most pre-op contracts explain side effects that are possible with surgery.  Once you sign the contract, you agree not to sue the doctor for possible mishaps that happen as a result of the surgery.  However, if your particular side effect was not listed, or the doctor acted negligently, you may still have a claim.  The doctor’s actions after the mistake will also be considered - for example, whether he lied to you about his mistake and if his actions caused additional hardship to you.
