A cavity typically looks like a small spot or hole on a tooth caused by decay over time. In the early stages, it may appear as a white or chalky spot on the tooth enamel, indicating demineralization. As the cavity progresses, it often turns brown or black and may develop into a visible hole or pit on the tooth surface. The affected area can feel sticky or rough, and the discoloration can range from light brown to dark black. Cavities can also cause the tooth to have a wedge or conical-shaped decay pattern in the enamel. In advanced stages, the hole becomes larger and darker, sometimes accompanied by gum swelling or bleeding near the tooth
. On dental X-rays, cavities appear as darker spots or shadows on the teeth, distinguishing them from fillings, which show up as brighter areas
. In summary, a cavity looks like:
- Early stage: white or chalky spot on enamel
- Progressing stage: brown or black spot, possibly with a small hole or pit
- Advanced stage: larger dark hole or crack in the tooth
- On X-rays: dark shadow or spot on tooth
These visual signs often come with symptoms such as toothache, sensitivity to hot or cold, bad breath, and gum irritation
