Absolutely horrible. I've never had a cavity or needed much dental care so I was only getting my teeth cleaned here for a long time until he recommended that I replace the crowns on my front teeth, crowns I had had for 17 years. Two years later I'm with a new dentist and having to have them replaced again. The dentist I have now was shoked by what a poor job that was done before. They look bad and my gums have been swollen and bleeding ever since Dr. Katnik replaced the crowns. The ladies that clean your teeth are nice but that is about the only thing good I have to say about my experience in this office.
