Decay typically (but not necessarily) starts as a dull white band on the smooth surface of the tooth at the gum line, followed by yellow discoloration. Depending on many factors, including saliva pH, presence of fluoride, removal of plaque, and modification of the substrate, this lesion can become remineralized. Ideally, this is the time for a dentist to begin treatment intervention. If left untreated, white spots will lead to cavitation. |
