Hi,
I don't have their insurance but I am an insurance underwriter.
At those rates you are definitely covering 100% of premium so here are some things you should look at before leaping.
What are the costs of your families dental cleanings? Add those up, do they exceed 50% of the cost of insurance premiums or even 100% of the cost. At $110 the annual premium is $1320. At $75 the annual premium is $900. If yes, then the plan is worth considering, if no and you all have good teeth and no one is approaching the age that they need wisdom teeth removed, then you may want to re-think insurance.
If you decide you want to go with insurance some things to think about when comparing plans:
99.99% of dental insurance has an annual maximum. What is the maximum on each plan. Is the maximum $750, $1,000, $1,500, $2,000 or $4,000. So if the $110 plan has a $2,000 vs a $750 for the $75 plan you would proably want to go with the $110 plan as you are getting much more bang for your buck.
What is the deductible on each plan? Are you getting a $25 or $50 and how many times must you meet the deductible per family?
What are the benefit limits? 100% preventive /80% basic /50 % major /50% ortho or 100 major /50basic /50 major or 50/50/50 or 80/50/50, etc. and are there any excluded benefits and does your preventive apply to the deductible.
HTH.
