PPO dental plans are more widely accepted than HMO plans. PPO plans will also reimburse you if you receive services from an out-of-network dentist. You will always minimize your out-of-pocket costs if you use an in-network dentist. PPO plans have higher monthly premiums because of the larger network of dentists and the out-of-network coverage provided. None of the dental plans will cover implants, tooth whitening, or adult orthodontics.
