A small cavity might seem harmless at first. It often begins as a tiny black or brown spot on the tooth—sometimes without any pain. But what many people don’t realize is that a cavity never heals on its own. It's a sign that bacteria have already started breaking down the tooth enamel, and if left untreated, that tiny hole becomes deeper and wider over time.
As the cavity grows, it reaches the softer inner layers of the tooth, especially the dentin and eventually the pulp, which contains nerves and blood vessels. At this stage, you may start experiencing sensitivity, pain, or even swelling. By the time symptoms appear, the damage is often severe. The infection can spread deep into the root, leading to abscesses, bone loss, or the complete breakdown of the tooth structure.
What started as a small, easily treatable issue can now require complex treatments like root canal therapy or even tooth removal. That’s why early detection and timely dental checkups are so important. Fixing a small cavity is quick, painless, and affordable—ignoring it could cost you your entire tooth.
