MDP is a discount dental program. This is not an insurance company. MDP, Inc is constantly adding new providers to our list.  Occasionally a provider will no longer wish to participate but may still be listed on the website or on other literature.  Because of this all Members must verify services with each individual provider prior to your dental visit. Members must be enrolled in the Plan prior to visiting a participating provider to guarantee benefits. Participating providers are independent contractors and are solely responsible for all treatment provided. MDP makes no verbal or unspoken warranties regarding services received, and disclaims all liability for any and all services performed by participating providers and their associates. There are no out-of-network benefits. MDP DOES NOT PAY CLAIMS.
