Which fluoride treatment should NOT be applied immediately following coronal polishing?

The choice of stannous fluoride as a treatment that should not be applied immediately following coronal polishing is significant due to its potential effects on teeth. Stannous fluoride has a known propensity to cause staining in dental structures. This staining can be exacerbated if applied to teeth that have recently been polished, as the polishing process removes surface debris and can leave teeth vulnerable to discoloration.

Coronal polishing aims to create a smooth, clean surface on the teeth, ideal for subsequent treatments. When a potential staining agent like stannous fluoride is introduced right after this process, there is a risk of reversing the aesthetic benefits of the polishing. Therefore, it is often recommended to delay the application of stannous fluoride until a later time to avoid any staining issues.

In contrast, treatments such as sodium fluoride, fluoride varnish, and fluoride rinses do not have the same staining concerns and are generally safe and effective options to apply immediately following a polish. These treatments can provide immediate protection and remineralization benefits without compromising the visual appearance of the polished teeth.
