It's A Sign
Toothache pain is the worst. You can’t see it, it doesn’t go away on its own and you can’t massage it like a muscle knot. It’s also a loud indicator of a serious problem that requires immediate attention from a dentist.
Most toothaches are the result of tooth decay, which means you probably have the result of that tooth decay or advanced gum disease. The pain you feel – usually when you eat or drink something sweet, very hot or very cold – is an alarm bell telling you that the pulp is irritated. The pulp is the inside of your tooth, where the tissue and nerves are located, so if something is wrong with the pulp, you’ll feel it in the entire tooth.
