Q.
I had several “procera” crowns fitted just over 2 years ago most of which replaced older crowns fitted around 20 years ago. One of the new crowns fell out 12 months ago and was refitted. This has recently again fallen out and another has also fallen out without warning. It would appear that the crowns were fitted onto posts that were fitted 2o years ago. I now have 2 prominent gaps and am having problems getting the crowns refitted. I am worried about infection to my open gums. What is your advice please.
