Dr. Boenning replaced 20-year old crowns in my 2 front teeth. The old ones were thick and off color and lined with silver in the back. If I threw my head back and laughed, I knew that silver was showing. The new crowns were like real teeth. They were translucent, thin as real teeth, and the correct color. I love them. I was even self pay, but he was worth it! The first set of crowns came back and were just a shade off, and he sent them back for the right color. He's the best. I only wish I lived closer.
