Greenville Smiles

I had all my teeth pulled out the they did 4 implants to hold dentures in .I spent 8, 263.80 just for my dentures the first part the pulling of all teeth was even more .I have been back to dentist 4 times for him to repair my broken teeth he blames me said I need to get an extra set for 1400.00 more. Why would I do this when the first ones are obvious not good dentures ? What can I do about this ? I think for the price I have paid and the pain I have been in for the last few months and never going a month without my teeth breaking the dentist should replace the whole thing, They are a transparent looking cheap looking base and even look cheap the teeth look good but useless if they break all the time .. I finally just got my teeth in May of this year because they were doing the dental implants that's why it has taken so long .What can I do, when The dentist says its my fault that they are breaking ? I was eating a piece of bread this last time and they broke. I was getting ready for Thanksgiving dinner also and I have had a bad holiday still grinding my food .
