It would be advisable to speak with a medical malpractice attorney.There isn't any mathematical formula for determining the amount of your compensation.  You should obtain the medical bills and medical reports.  The medical (dental) reports will document the nature and extent of your injuries and will be used to determine compensation for pain and suffering.  Compensation for pain and suffering is an amount in addition to the medical(dental) bills.  Compensation for the medical (dental) bills is straight reimbursement.  Compensation for documented wage loss is straight reimbursement.Prior to filing a lawsuit, file your personal injury claim, consisting of the medical (dental) bills, medical (dental) reports and documentation of wage loss, with the dentist's insurance carrier.  If the case can be settled with the insurance carrier prior to the expiration of the statute of limitations, no lawsuit is filed.  If the case is not settled, you will need to file your lawsuit for negligence against the dentist prior to the expiration of the applicable statute of limitations or you will lose your rights forever in the matter.When filing your claim with the dentist's insurance carrier, I would ask for quadruple the medical (dental) bills to compensate for pain and suffering, but not expecting to get that.  This would be a starting point in negotiations.  The insurance company will respond with a lower offer and you can continue negotiations.  If you are dissatisfied with settlement offers from the insurance carrier, file your lawsuit for negligence against the dentist.  Any settlement should be sufficient to compensate you for the estimated cost of future treatment because once the case is settled, you won't be able to obtain additional compensation.  Again, your lawsuit must be filed prior to the expiration of the applicable statute of limitations or you will lose your rights forever in the matter.
