Typically, tooth sensitivity is caused by exposure of the dentin, or middle layer, of the affected tooth. This usually is due to enamel erosion and gum recession. Your tooth roots, which are not protected by enamel, contain tubules that lead to the center of your tooth, where the dental pulp is. Tooth sensitivity is a common problem, with up to 33% of the population reporting it. This condition is most common among adults between the ages of 20 to 40 and women are more likely than men to report it.

A cavity is a small hole in the tooth enamel caused by decay. Tooth sensitivity is tooth pain due to the dentin being exposed to certain stimuli such as heat or cold, excessively sweet or sour foods or beverages, and acidic foods or beverages. The best way to confirm whether you have a cavity or sensitive teeth is with a dental checkup. If there are no holes in your enamel, you have sensitive teeth. If you have one or more holes in your enamel, you have a cavity. No, sensitivity to cold does not necessarily mean that you have a cavity. There are other reasons that your teeth may be sensitive to cold including: gum disease, brushing too hard, clenching/grinding, receding gums, and cracks/chips in teeth.
Dental pulp is made up of blood vessels and nerves which keep your teeth healthy. If a tooth is damaged, the stimuli (heat/cold, sweets) can reach the nerves, which is what causes pain.
In some cases, tooth sensitivity is an indication of other issues including cavities, gum disease, and more.Causes of Tooth Sensitivity
