Dr. Feder seems to take pride in his work, which I see as a very good sign. He is willing to spend extra time to make sure that a filling or crown is just right. While I'm not qualified to professionally judge the quality of his work, he does seem to be active and respected in the LA dental community, and I'm happy with the work he's done for me.
Without a doubt the best thing about Dr. Feder is his hygenist, Nina. There is no doubt in my mind that this woman has saved me thousands of dollars of dental work. She doesn't just clean my teeth, she takes an active role in making sure that I am taking the best possible care of my teeth. When she saw excessive tartar, she didn't just tell me to floss more like other hygenists have: she showed me how I should be flossing. And when I got it wrong, she showed me again, and again. These days, removing the tartar takes about five minutes. I like Dr. Feder, but if Nina ever leaves, I'll switch dentists to follow her.
Dr. Feder has a laser device which he can use instead of the drill to clean out cavities with no novocain and no pain. No vibration! No needles! No numb lip!
He's not the cheapest dentist, but his prices aren't sky-high.
