I know that the high acidity of acidulated phosphate fluoride should not be used in patients with ceramic crowns. Is there an alternative fluoride treatment for patients with ceramic restorations?

Yes, neutral sodium fluoride formulations can be used topically in patients with ceramic restorations. One such product is Denti-Foam (MEDICOM, Inc.) neutral sodium fluoride (NSF) formula. Note – neutral formulations require a longer exposure time than acidic formulations. The product should be placed in a tray and inserted into the mouth for four minutes.
