Do I have a case if I had a root canal that was not done right?

6 years it took you to figure out the work was done wrong? A dentist can look at the tooth today and say what happened 6 years ago? If so and he is willing to testify you may have a case. What is it worth? Who will pay your lawyer? Have you talked to the dentist about his liability insurance. What does he say about it all? See a good PI lawyer for full review.

Six years, way too late.

It takes a medical expert to answer that question. Medical malpractice lawyers who do dental malpractice cases have such experts available. Consider consulting one.

Medical and dental malpractice claims are, by their nature, very difficult. Under California law, it is necessary, before filing suit, to obtain an affidavit from another professional, verifying that he has reviewed the medical charts and has found that there was negligence. This can cost several thousand dollars, and most attorneys expect that the client will cover this cost. Negligence could be defined as the failure to use REASONABLE care; not all bad outcomes are the result of negligence. You should also be aware that there is a cap on the amount of recovery for ?pain and suffering?, thanks to the doctor lobby. Sometimes one has a good case theoretically, but the damages are too small to warrant a suit. For these reasons, not many lawyers handle malpractice cases. You should seek a specialist. You can contact your LOCAL bar association for a referral.

So sue.
