Dental insurance companies sort different types of dental procedures into different classes.
Class I is for diagnostic and preventative care including some X-rays, exams, and cleanings.
Class II is for basic care such as fillings.
Class III dental care usually refers to major procedures including dentures, bridges, implants, and crowns.
Class IV dental procedures are orthodontics.
Different companies provide various percentages of coverage in these areas. For example, one insurance provider might cover 100% of the cost of Class I services while another might only cover 80%. Yet another plan might not provide Class IV or orthodontic coverage but provide coverage in all other areas. It’s important that you understand what services are covered before signing up for a plan.
