My humble opinion here:

1- the "cut out the insurance middleman" is just huge and don't tell me what your site is about

2- "EZ dental membership software for managing your new/existing in-house dental plan" - Got a bit confused as to what EZ dental is, as I thought this should be actually OK Dental. Also still don't know what is it that you are selling

3- "Sign Up for free" - for what? what is it that you are selling? who are you?

4- Now I see the screenshots with the stats and below it some useful information and understand more what you are offering.

I suggest you hire a professional designer to re-design your landing page as it is so confusing, size of fonts is just too big in places, I had to spend way too much time to even understand the niche you are targeting.

If you are targeting dentists, then go where they are online/offline. I would find a forum/webpage where there are a lot of dentists and buy an ad there. Alternatively just visit them and see if they are interested.
