In my opinion Kuzmin is a ham-fisted clod. He unsuccessfully placed 3 crowns on my new implants. They were too low. I said they were too low. He cemented them anyway. They were too low. My bite was off, I was getting headaches. Rather than do the correct (and ethical) thing and replace the crowns (that he had been well paid for), he tried to fix the problem by grinding down my teeth on the opposite side. My bite is permanently damaged. Other dentists have tried to fix his terrible work and all are shocked that he would ruin perfectly good teeth rather than correct his error with placing crowns that were too low. Never, ever see this unprofessional, poorly skilled, unethical dentist.
