A Preferred Provider Organization (PPO) is the most common type of dental insurance. It gives you a list of dentists to choose from who have agreed to charge lower prices. This helps you save money. PPO plans usually pay for part of your dental care—100% for cleanings and check-ups, about 80% for things like fillings, and around 50% for bigger treatments like crowns or bridges. Most plans also have a yearly limit of $1,000 to $2,000 and help with billing your insurance.
