<prompt> Human: I read on the internet that dental insurance does not have pre-existing conditions issue like health insurance does. I feel Im due to have crown replaced which can cost by several hundred dollars. Im currently working a part-time job without insurance benefits, and cant go full-time because of school.  <response>: Youll want to read through any plan youre evaluating very carefully. Most dental insurance doesnt work like health insurance - it is generally a reimbursement plan with a fixed cap for specific services. For example, the plan might cover Xyear for cleanings, Yyear for fillings, etc. and it may not be beneficial to buy into the plan just to use one or two of the benefit categories. Most plans also come with waiting periods. Instead of excluding pre-existing conditions, you may need to wait 6-18 months after enrolling before you are eligible for certain types of coverage. You might be able to use cleaning benefits on Day 1, but not coverage for root canals until 12 months.
