My wife had her wisdom teeth removed by Dr Provenzano in the spring of 2010. The procedure resulted in her losing any sensation of taste on one side of her tongue. She contacted him a week after surgery and was completely dismissive of her symptons and he said that was not possible (which it is with the lingual nerve being severed).
In a testament to his knowledge, he insisted that generic, over-the-counter painkillers are not the same as their brand name equivalents.
This was a horrible experience. We were treated in an unprofessional before the surgery, the surgery was sloppy and possible permanent nerve damage was done, and we were treated in a manner afterwards that was more about him covering his rear than trying to resolve that problem.
