Do Metal-Ceramic crowns harm your gums? Long-Term study investigates
NCT ID NCT07500636
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study followed 32 people who received a single metal-ceramic crown to see if it causes gum changes over 8 years. Researchers compared the gum health around the crowned tooth to the same natural tooth on the opposite side of the mouth. They measured plaque, bleeding, pocket depth, and gum recession during routine dental exams.
