The average family of four in the U.S. will see an average $4,000 increase in their health insurance premiums next year, according to a new study.

The National Association of Insurance Commissioners said the average premium for a family of three will increase to $9,200 for the 2017 season from $6,600 in 2018.

The average premium increase for families with children will be $3,000.

The average increase will be even more steep for seniors and people with pre-existing conditions.

The group estimates that the average annual increase will go up to $25,400 for an individual and $42,600 for a couple with children.

The association said the new premium increases will make it impossible for Americans to afford the same health care coverage that they currently enjoy.

The study also found that the cost of dental care in the United States will be the highest it has been in 20 years.

The cost of dentures is estimated to be $1,907 per tooth, up from $976 in 2016.

The association also noted that the typical cost of a checkup will increase by $400.

The group said that, because of the cost, the average family will spend more on health care than they do on food and other basic necessities.

The increase in dental costs is a result of a number of factors, including a shrinking number of dentists, the rise in cost of treating dental conditions and the rising cost of insurance premiums, the group said.
