Why are some porcelain crowns rough instead of smooth?
Answer Dear Sarah, There are several possible reasons why your porcelain crowns may feel rough: – the porcelain was not properly glazed – the margins of the crown do not accurately follow the contours of the tooth to which it is cemented – your dentist adjusted the contours of the crown with his drill and did not follow up by either polishing or re-glazing – your dentist allowed some excess luting cement to remain. Ideally, ceramic crowns should be smooth. Your questions are a legitimate concern, and it would be perfectly appropriate for you to ask them of your dentist. If he is not sufficiently candid about assessing his own crowns, you might want to have another dentist evaluate them. Hope this helps…
