dr brown did 4 fillings for me when I was 16-18 years old. since then I have had several other dentists ask me who did them because they were done so poorly. I am now 30 and I just had a filling split my tooth, cracking it in 2 places. when my dentist repaired it he said "the way these fillings were done could be grounds for a lawsuit". dr Brown apparently took out way too much tooth, carved it out down to the nerve, and then did not put the normal buffer layer but instead put straight mercury filling on top of the nerve. angled like a wedge on a log my current dentist said it was only a matter of time before it split my tooth. now I may look at losing a tooth at age 30 when every tooth untouched by dr brown is in perfect condition. the other fillings I have were done the same way, some with 2 different types of material, another thing that has baffled other dentists. one said it looked like he used whatever he had lying around". I hated him as a kid because of he was so cheesy and dorky, and now he has ruined my teeth.
