This is absolutely TRUE. I once had to have an emergency Root canal, much more expensive than an extraction. I was only able to come up with 1/4 of the money, but I was able to find a dentist to help me out, and I paid him off over the next few months. An extraction? Those are pretty cheap last I checked, unless the tooth is impacted, like a wisdom tooth or something.
And a heads-up to Freepers like myself who tend to put off dental work. Bad teeth can lead to a host of other problems, including CARDIOVASCULAR disease. Bite the bullet and get those teeth fixed!
My Dad's best friend and my Godfather is a dentist. He charges us his costs for our work (for his assistant, anything he has to order etc)
He said the thing about seeing your dentist twice a year saves you a lot of money in the long run. Very few expensive problems will develop in less than 6 months.
