Eligibility and Enrollment

All benefit eligible employees may enroll themselves and their eligible family members in one of the two dental plan options described below.  Employees pay the full cost of the Dental plan. 

New Hires may enroll within their first 30 days of employment, otherwise existing employees may enroll during the annual open enrollment period held each fall for a January 1st start date.  Some qualified life events causing a drop in external dental coverage will allow for enrollment in a dental plan for yourself and/or your dependents.

ID Cards

Please allow 7 to 14 days from new hire enrollment for new ID cards to arrive in the mail. You will receive two identical ID cards, to cover any and all members of your family.  During open enrollment, you will not recieve new ID cards unless you are new to a plan. Cards will arrive prior to the new year. If you lose your ID card, please contact Delta Dental at the number above, or you may access and print a copy through your online account.

Orthodontic coverage is available for both children and adults, under the Dental HIGH plan. The $2,000 orthodontia lifetime maximum is per covered family member and is separate from the $5,000 annual plan maximum.  Patients who are already undergoing treatment, may be eligible for a portion of orthodontic coverage based on the length of active treatment remaining.  Please review and share the payment schedule below with your provider to determine the amount of reimbursement that will be available.

Leaving Dartmouth

Can I Continue Dental Under COBRA?

Yes, the same rules apply for Dental coverage under COBRA as they do for Medical.  See information on COBRA coverage and rates on our Leaving Dartmouth webpage.

Where Else Can I Buy Dental Insurance?

New Hampshire Continuation of Coverage (COC). In addition to your COBRA packet, New Hampshire residents will also receive a packet offering continuation of dental coverage (COC) through the State of New Hampshire.

  • Plans - The NH COC is a continuation of your existing Delta Dental plan.
  • Costs - The same as your Dartmouth Coverage, but the state of NH does not charge the additional 2% admin fee that you pay with COBRA.
  • Coverage Ends - NH COC continues for 18 months, same as COBRA
  • ID Card – You will continue to use the same ID number/card that you used as a Dartmouth employee, whether you continue through COBRA or NH COC.
  • No Coverage - There is no IRS penalty for canceling dental insurance.

What Happens When My Dental Coverage Runs Out Under COBRA or Through the NH COC?

You may be able to purchase a private dental plan through North East Delta Dental or another dental carrier that covers your geographic area.
