When buying a Dental PPO or Indemnity insurance plan, make sure to pay attention to the maximum amount of coverage allowed. A comprehensive plan should have at least a $1,000 maximum coverage, but the average range is between $1,000 – $2,000. A major dental procedure can cost hundreds if not thousands of dollars, and you can easily max out your insurance in one trip. When comparing different dental insurance plans, compare the coverage limits. Higher limits usually require higher premiums, but they may be worth it if you require multiple dental procedures.
