If you’ve noticed a bothersome orange tint, you may be wondering about the cause, whether it’s worrisome, and how to address it. Typically, plaque is more white than orange, but that doesn’t mean different colored plaque is worrisome. Orange plaque is actually a result of extrinsic stains on your teeth, originating from external sources rather than internal factors. This discoloration is linked to the consumption of certain foods with an orange hue.
