Can porcelain teeth be postponed after piling?
Teeth need piling to keep them. Maybe the original root can't be grasped, so piling is needed. This has no effect on the mouth. You have black gums now. It should be that the porcelain teeth you made before are metal, and the metal inside is free, which leads to black gums. If you want to do it again now, it is recommended to choose all-ceramic materials. All-ceramic materials will not cause black lines on gums. All-ceramic is much better than metal in aesthetics.
