I had a post and crown done in April 2008, it fell out and had to be replaced six months later. Now the post and crown fell out again. After talking with his office they said they would pro rate the cost, because it should last 5-6 yrs. However, they spoke with dr. Nunn he said it would be full price because he already replaced it for free. I thought replacing it 6 months later was because of poor installation. And to not pro rate it after collecting thousands from my wife and I and our insurance companies just proves greed. He is expensive and no I do not recommend this dentist
