Before I get into dental insurances, let me introduce two terms to you. Dental plans are the insurance plans that your dental insurance companies promise to cover you under the contractual responsibility they have had with your employer or the subscriber (that is You). Treatment plans are the plans your dentist develop for you and with you and are based on your needs and desire and are meant to be the best for your dental health. Ideally, your dental plan will cover every treatment plans you need and you want. Unfortunately, this is often not the case because insurance companies are to make money, not to satisfy every need of their clients.
