Hello,
My father had to go through two brain surgery to remove absess from his brain. He is recovering but can't talk very well. the absess was caused by the infection in his teeth. unsanitized dental equipment causes infection which can cauase brain absess. any advice please! thank you!

In dental malpractice cases, it is required to PROVE that the dentist was negligent that caused your father's injuries. It must be based on expert testimony from another dentist that the first dentist was negligent.
