Dental plans are similar to medical plans in that choices are available. What you elect to have included impacts monthly premiums.
Preventive care, like regular cleaning and exams may save you money over time. Catching problems early helps minimize the need for major procedures. As with medical plans, various factors need to be considered when selecting a dental plan.
Paying for a larger portion of the initial costs out-of-pocket reduces monthly premiums. You may want to consider your dental history when looking at this component.
Using dentists who are "out-of-network" increases your flexibility but can raise your costs.
Every time you see a dentist, get an x-ray or have your teeth cleaned, you may need to pay an out-of-pocket co-pay. Keeping this small impacts premiums.
Other features can be added or modified to provide more comprehensive coverage. Which of these to select depends upon your specific requirements.
