1. The teeth near your gums aren’t very bright or shiny.
The teeth under your gums appear darker because they lack the protective shield of enamel. That’s why when your gums are receding and you’re showing more of your teeth, the ones that show might be a bit more yellow or darker. Teeth without enamel are exposed to all sorts of bacteria and germs. This becomes a problem that goes deeper & compromises the teeth’s general health.
