What should I run beside, a Discount Dental Plan or Dental Insurance?

My fiance comes from a not so wealthy background or household and is having huge issues because her wisdom teeth own started to come in finally. She does not have Dental insurance and can't afford it but she requests the wisdom teeth extracted as they are impacted and causing severe twinge in her jaw. I be looking at dentalplans.com and noticed these "discount dental plans" where it offer discounts on the costs of the procedures instead of just normal dental insurance. Are these lawful? Or are they just not worth it?
Answers:
healthplans.bebto.com - my family own this health insurance. It is affordable and has righteous coverage for dental issues.
You can also purely shop around - dentists like to make deal to get the business.
