Insurance
With all the identity theft going on, a lot of people are legitimately asking, "Do I need to give out my social security number at the dentist's office?" If dental insurance is involved, the answer is ideally no, but the reality is sometimes different for some carriers.
Medical insurance and car insurance protect you from catastrophes that can bankrupt you. Rarely do dental crisises cost anywhere near what a medical illness or a injury-involved car accident can. Because of this, dental insurance isn't critical. In fact, it's a game that individuals and families cannot win.
The main differences between a PPO and an HMO plan is how the doctor's office is paid, how much you the patient are paid, and unfortunately, how you are treated and diagnosed. When you understand these important disctinctions, you will understand why it makes a big difference which one you choose.
