Any recommendations for private dental insurance?

I broke a tooth eating a Clif bar of all things two nights ago. I had to pay the dentist $1096 today for the new crown and the work. Last year one of my little guys had $5000 of dental work done on his baby teeth (yes, his baby teeth). Year before that, my husband had a couple of thousand dollars worth of dental work done. I’m seeing a pattern here. Our dental problems seem to be exceeding our medical bills as of late. We haven’t any dental insurance but I’m thinking we probably should. I have a couple of older molars with those big of silver fillings they used to do back in the 60’s and 70’s and I wouldn’t be surprised if they will eventually go too considering I’m in my 50’s and these teeth are at least 45 years old. So, any suggestions on where to look for decent coverage?
