New for 2027: MetLife Dental

Starting Jan. 1, 2027, dental PPO options will be insured by MetLife Dental. The plans are: Preventive Care, Dental Care, and Dental Care Plus. All plans cover eligible preventive care at 100%, with the flexibility to receive dental services from both in-network and out-of-network dentists.

You will receive an ID card from MetLife Dental, but it isn’t required to obtain services. You can also access and print an ID card on the MetLife Dental website.

Save More When You Stay In-Network

You have the flexibility to visit an in-network or out-of-network dentist but using an in-network MetLife dentist can help you save.

MetLife negotiates discounted fees with participating dentists. These negotiated fees can reduce the price on which your share of the cost is based, helping your dental benefits go further.

A Large Nationwide Dental Network

MetLife’s dental network includes more than 133,000 licensed dentists across more than 470,000 locations nationwide and continues to grow.

The extensive network includes general dentists and specialists, giving you more options when looking for convenient, in-network care for yourself or your covered family members.

Visit MetLife to find participating dentists in your area and access additional information about your dental coverage.
