@5d_smile: Your tooth enamel actually acts like a sponge. Just as a sponge absorbs liquids and holds onto them, your enamel has tiny pores that soak up the pigments from the things you consume every day. When you drink a lot of coffee, dark sodas, or tea, those stains do not just stay on the outside where a toothbrush can reach them. Instead, they seep deep into the pores of the enamel and settle inside. This is why you can scrub your teeth multiple times a day and still not see a change in color. You are cleaning the surface, but the stains are already locked within the structure of the tooth. Understanding that your teeth absorb stains like a sponge is the first step to knowing how to actually get your bright smile back. #TeethWhitening #DentalCare #HealthySmile #OralHealthTips #EnamelHealth
