Pain from sensitive teeth manifests itself when eating or drinking something hot or cold. It can vary from a slight discomfort to a full out “ouch!” moment.
Tooth sensitivity is a condition that is quite common and can be caused by a variety of different issues. It could be due to tooth decay, or a cavity, gum disease, worn tooth enamel, a broken or fractured tooth or filling, or an exposed root.
Enamel covers the crown of the tooth, or its exposed part. This acts as a natural protector against acid and stains. Underneath the gum line is a substance called cementum, which protects the roots of the teeth. Beneath these protective layers is the dentin of the tooth in which lie canals or tubules that are hollow. When the protective enamel or cementum erodes, the dentin can sense pain
Dentists can reduce or eliminate sensitivity by addressing its causes.
