dental insurance is kinda of a scam, if you are not using an employer-sponsered one, they dont cover most things outside of cleanings. the ones i looked from the 3 well known dental insurance, have approximately the same kind of coverage for all 3 plans, the only difference some of them are more expensive. Employer- sponsored plans have very different coverage from the individual plans.
i like how they rail about dental/health insurance as a scam, while they use a more expensive version which is likely paying the full cost of dental care. i would imagine the fund would drain pretty fast if people are getting multiple cavities filled, and not even for other things like extractions, root canal and crowns, or periodontal care, or implants.
I ALSO notice some dental offices, offer thier own "insurance" in house, may or may not be expensive but that could be another avenue if people dont want to pay for better insurance.
