@explainingmadicals: explaining.medicals What looks like a tiny black spot on the surface of a tooth can sometimes hide extensive decay underneath. Tooth enamel is the hardest substance in the human body, but cavities can spread beneath it before becoming obvious from the outside. As bacteria feed on sugars left behind in the mouth, they produce acids that gradually dissolve the enamel. Once the decay reaches the softer dentin, it can spread much more rapidly, creating a cavity that is far larger than the small surface opening suggests. During treatment, the dentist carefully removes all infected tooth structure while preserving as much healthy tissue as possible. The cleaned cavity is then restored with a tooth-colored composite filling, which seals the tooth, restores its strength, and helps prevent bacteria from entering again. Because early cavities often cause little or no pain, regular dental checkups are essential for detecting hidden decay before it reaches the nerve and requires more extensive treatment, such as a root canal. Sometimes, the smallest visible spot is only the beginning of what's happening beneath the surface. #LearnOnTikTok #MedTok #fyp #Surgery
