I had a root canal on #2 and am now getting a crown. Dentist told me a gold crown would be strongest, but her second choice would be all-ceramic. Last choice would be PFM. I chose all-ceramic based on what she told me. This was all new to me because my previous dentist never gave me a choice, he always used PFM. After reading online, I'm upset because I don't think all-ceramic was best choice. I have a PFM crown right next to it on #3. I did molds today. Is it too late to change to a PFM?
