Had crown put on tooth incorrectly and less than 18 months later tooth decay at gum line. I have had several crowns put on over the years and never had this happen. I moved away and dentist here said should not happen this quickly. When contacted, Dr Kemp would not take blame. Instead, insisted that dentist in Charlotte is trying to rip me off. However, Dr Kemp wanted to put on two additional crowns that current dentist says is unnecessary. Dr Kemp in my opinion is unethical.
