We used to see Dr. Ezaki on Sand Canyon in Irvine and I think he also owns the Apex group. Do NOT see him...felt like everytime we were there he was trying to sell us something new...always claimed we had this wrong and that wrong.
We went to a new dentist recommended by a friend about eight months ago and low and behold, our troubles are not what Dr Ezaki led us to believe. Although I can tell you I need to have one of my fillings that Ezaki did replaced because it's cracked and it's only about two years old. Lovely.
We've also taken our four year old to this new dentist and he was great!
I recommend Dr. Jonathan Cho, he's at the corner of Barranca and Jamboree. Phone is ###-###-####.
Good luck!
