Hello Doctors, I have two questions. I need a crown on a molar (that is noticeable when I smile). I would like to go with porcelain fused to high noble metal. I would first like to know what guarantee/warranty I should get, and if I should get it in writing. I would take the best care of my tooth possible. An excellent dentist in Mexico can give me a 5 year written guarantee. But, I would rather stay in the US. Also, what is the best percentage of metal to porcelain? Is 30-40% metal standard?
