Hi A.,
My husband is a broker for life, health, and dental insurance. He rarely recommends dental insurance for his clients because it is usually not worth the expense. Everyone's situation is different so it is probably worth talking to an insurance broker, but don't expect to save a lot. If you want, you can call him - his business is Advantage Brokers of Colorado. ###-###-####
Some dental plans do not cover pre-existing conditions. There are others that do not cover any major expenses the first year.
My husband did say that quite often you can negotiate the cost with your dentist (this is very common for orthodontics). Dentists do not like dealing with insurance companies and they may be willing to lower their cost. As a last resort, almost all dentists do offer payment plans with 0% interest.
Hope that helps!
J.
