If you had dental coverage when you stopped working, then you can often keep this coverage at the COBRA premium. This coverage lasts for 18 months. If you meet the eligibility criteria, you can enroll in retiree dental coverage when your COBRA coverage expires. You will need to contact Benefits Administration 60 days prior to the expiration of your COBRA coverage to request an application to enroll in the retiree dental plan. You must indicate the requested future effective date when you submit your application.
