Final answer:
Decreased fluoride uptake is not a negative effect associated with coronal polishing. This procedure can potentially cause dentinal hypersensitivity, loss of enamel, and rough surfaces on restorations but not affect fluoride's ability to strengthen teeth.
Step-by-step explanation:
The question pertains to the negative effects of coronal polishing, a dental procedure. A possible negative effect that is not usually associated with coronal polishing is decreased fluoride uptake. Coronal polishing is used primarily for removing stains and plaque from the tooth surface. While it can cause dentinal hypersensitivity because the process may remove a minuscule layer of enamel, potentially exposing the dentin, the treatment itself does not typically affect the uptake of fluoride by teeth. The fluoride uptake process primarily involves the remineralization of teeth, in which fluoride helps to rebuild the tooth's mineral content, thus strengthening it against acids from plaque bacteria and sugars in the mouth. Prominent negative effects of coronal polishing include loss of enamel if performed excessively, creation of scratches or rough surfaces on restorations, which may harbor bacteria and ultimately lead to tooth decay, and dentinal hypersensitivity. However, as part of general dental hygiene, fluoride treatments and fluoridated water are beneficial for strengthening teeth and preventing decay.
