Yeah it's very limited in general. You can't even get certain standard types of cleanings with 100% coverage because it's not a supported dental code.
It would be way more efficient for employers not to offer dental insurance and instead give employees a tax-free $1,000 yearly stipend which allows employees to use this for personal and family dental care as an expense report which in turn ends up being a business write off for the employer. Now there's no limitations on what work can get done and no wasting your life trying to chase down dental / FSA details. A higher end dental insurance plan through a company is over $1,000 a year too, so this stipend approach would save employers money and it saves employees a lot of money too because you could easily end up paying $600-700 post-tax money out of pocket for standard cleanings a few times a year when insurance won't cover them (even if that insurance costs $1,000 a year). It's a win / win scenario for both the employer and employee.
