Under the laws of most states in this country the statute of limitations for billing for services or product provided a customer in order to file suit such as services provided by a dentist is four (4) years.However, from a business standpoint, imagine how a patient feels about getting a first time bill from a particular dentist for services three (3) plus years after the services were provided. It does not make the dentist sending the bill seem like he or she is too astute of a business person paying attention to detail.
