Yes, it is generally possible to add dependents to a Metlife Dental plan, but the specific process and eligibility requirements may vary based on the plan and the employer's policies. Typically, dependents may include spouses, domestic partners, and children. To initiate the addition of dependents, a policyholder would usually need to fill out a specific enrollment form, which can often be found on the Metlife website. It is important to note that there may be designated enrollment periods during which changes can be made or specific qualifying events that allow for mid-year changes, such as a marriage or the birth of a child. For the most accurate information, it is advisable to review the details available on the Metlife Dental website or consult the plan documents provided at the time of enrollment. Visiting the website will ensure that you have the most current information pertaining to adding dependents to your specific plan.
