The question of whether or not you can sue a deceased dentist is a complex one that depends on a number of factors, including the laws of the state in which you live, the nature of the claim, and the availability of the deceased dentist's estate.
In general, however, the answer is yes, you can sue a deceased dentist. However, there are some important caveats to keep in mind. First, you must file your lawsuit within the statute of limitations for medical malpractice in your state. Second, you must be able to prove that the dentist was negligent and that their negligence caused your injuries. Third, you must be able to collect on any judgment that you obtain.
