Dr Meden, did and root canal in my upper two front teeth. Those two teeth had crowns and he recommended veneers to replace them. After the veneers were placed because of their transparancy your could see the root canals through the teeth. Dr Meden then claimed that I should have asked for a different type of tooth and tried to make me pay again to fix the problem. A good dentist should know what type of tooth to use from the beginning.
