Tooth badly stained and discolored. Should I be concerned?
Currently on tray 29/29 of Invisalign and waiting for my refinements, I’ve noticed one tooth looks more discoloured than the rest. My teeth were pretty white before treatment I have had the odd few times where i’ve drank with them in and brushed later but for the most part been on top of everything. Does this look like possible decay, staining, or something else? No pain, just worried about the colour change. Has anyone experienced this during Invisalign?
