The separation of insurance between Dental Health Insurance and Standard Bodily Health Insurance does not serve any positive or beneficial purpose to the Health Care Consumer. The United States should adopt a policy that treats oral/dental care the same as any other body system. It has been proven time and again that poor oral care leads to a multitude of health concerns. While preventative care may be covered at full or near full cost, all the preventative care in the world is rendered meaningless if in the event you should need restorative care, you can't afford it.
No health insurance plan would only pay for vitamins, then if you get sick pay for only half your medical bills, and only up to $X.
Our teeth are part of our health and should be cared for as such. With Health Insurance.
