Tooth Sensitivity
Tooth sensitivity occurs when the dentin, the portion of the tooth that protects the nerve, is exposed, either via loss of the enamel covering or gum recession. Temperature fluctuations, as well as specific meals (acidic or sweet), might irritate the tooth or teeth. After a short amount of time, the discomfort typically goes away. The dentin has a high number of holes or tubes that go from the tooth's surface to the nerve in the centre. Changes in temperature or specific foods might activate these tubes after the dentin is exposed. What Causes sensitivity? ● Toothbrush abrasion: Brushing excessively hard or with a firm-bristled toothbrush can wear down enamel over time, exposing the dentin. It can also lead to gum recession. ● Dental erosion: It is the loss of tooth enamel as a result of acid assaults from acidic foods and beverages. When the enamel wears away, the dentine beneath it is exposed, which can cause discomfor...
