Inside every tooth, there's a soft area called the pulp. This pulp has nerves and blood vessels that help the tooth stay alive. These nerves are very sensitive — they can feel hot, cold, pressure, and pain.
When a cavity goes deep enough to reach close to the pulp, it irritates these nerves. That’s why you might feel sharp pain or sensitivity when eating something cold, hot, or even sweet. It’s your tooth’s way of warning you that there’s a problem.
If not treated in time, this sensitivity can get worse and may even lead to an infection or the need for a root canal. So, it’s important to catch cavities early and protect the pulp.
