Recently had zirconium crowns fitted. I don't like the surface, it isn't smooth. I don't think they were polished properly.

Question

My previous crowns were absoloutely smooth. My replacements are ridged/grooved, some back teeth have a dip/ cavity food gets stuck to them, I clean themfrequently they feel unclean, my tongue is raw due to being drawn to them. They're extremely uncomfortable, this will encourage plaque build up it's not hygenic. I think my crowns were not polished/finished properly before fitting. Please advise about the correct finish of zirconium crowns and what I should do about it. MT London

Zirconia is one of the hardest materials we use in dentistry. Because of this adjusting and polishing can be difficult however there are many products made for this exact purpose. Your concerns are legitimate as any surface can attract plaque and rough surfaces are no exception. I would recommend visiting your dentist to have this problem resolved. Hopefully this can be done in the office but if there was an error with lab processing and the entire surfaces of all the crowns are this way they may need to be remade.
