There can sometimes be significant differences between the dental insurance plans that employers sponsor and those that you obtain as an individual. One big (and obvious) difference is that usually employers pay for part or all of the dental insurance plan, whereas if you're buying a plan by yourself you have to pay for the whole thing. Some employers are also able to get a better deal because they're buying insurance in in bulk for all their employees. But, if you shop around, you could potentially get a plan that is similarly priced or even cheaper.
