It's pretty unlikely you'll be wandering Paris in shorts - especially since you're used to such warm weather -- the oldtimers count mid-May as the final frost date! (sometimes it works that way, sometimes it doesn't -- but they publish garden advice to protect your plants until mid-May).
Dental Health Maintenance Organizations (DHMOs) Defined. A dental health maintenance organization (DHMO) is a structured type of dental plan. In this type of plan, a set group of dentists provides broad and affordable care at a low monthly premium. The dentists who work with DHMOs receive a fixed fees each month. Most of the work is done at no cost or for a reduced price.
DHMO plans normally allow you to change your primary care dentist during the year if you are dissatisfied with the quality of treatment you receive. The Dental Health Maintenance Organization pays a participating dentist a certain amount per patient. Therefore, all the dentists who join in the organization agree to provide dental treatment to the plan's enrolled members as specified by the conditions of the dental plan.
