Tooth sensitivity is no longer an exclusive problem for middle-aged people. Data shows that over one-third of adults suffer from dental sensitivity, triggered by factors like consuming iced coffee, indulging in desserts, improper tooth brushing, biting hard objects, and high stress levels. These factors lead to sudden pain and accelerate enamel wear. When hot, cold, sour, or sweet stimuli reach the dental nerve, every bite of delicious food can turn into a "torture".
