While companies usually refer to medical benefits in terms of doctors' visits and hospitalization, insurance agencies contend that dental health is essential to overall health and should be included in any comprehensive benefits package. New medical studies show that oral infections (bacteria going into the bloodstream) can be a risk factor in cardiovascular and respiratory disease, diabetes, stroke and pre-term low birth weight. The American Dental Association maintains that additional research is necessary to establish a definite connection, but it says the evidence of a connection is growing.

In addition to improving employees' health, providing comprehensive dental care coverage can be financially beneficial for companies by preventing diseases that would cost more money and time in the long run. The dental industry is highlighting preventative care in particular in order to avoid expensive, painful procedures, as well as helping to eliminate a possible cause for more serious medical conditions, such as heart disease and diabetes.
