Why does it hurt when my teeth bite hard things?

Human teeth are very sensitive. If you eat some sour food or some hard food, it will cause toothache. This phenomenon generally does not last for a long time. Once the pain continues, it is likely that the gums are shrinking. At this time, you need to seek medical treatment. So why does it hurt when you bite hard things?

First, why does it hurt when your teeth bite hard objects? Teeth are composed of enamel, dentin, and pulp. Enamel is the first solid line of defense of teeth. Together with gums, it protects dentin, which in turn surrounds the pulp. When the dentin is exposed, hot, cold, sour, sweet foods, and foreign objects will penetrate through the countless pores in the dentin, stimulate the nerves of the pulp, and cause pain; when the stimulation disappears, the soreness will gradually disappear.

Second, chewing hard objects, toothpaste particles that are too rough, improper choice of toothbrush and improper brushing methods, etc., will cause long-term wear and tear, causing damage to tooth enamel, exposing dentin and causing sensitivity; acidic beverages and food corrosion, gum atrophy, exposed tooth roots, etc., will cause tooth sensitivity.

Third, how to reduce and prevent tooth sensitivity. Brush your teeth properly. Brushing your teeth vigorously sideways is the main culprit for damaging tooth enamel. Over time, it will cause damage to the protective layer of tooth enamel on the surface of the teeth. The most obvious sign is the grooves on the surface of the teeth. In severe cases, it will lead to pulpitis and tooth sensitivity. Please use a soft-bristled toothbrush, do not brush your teeth sideways, and do not use too much force to avoid wearing your teeth. If your teeth are already sensitive, it is recommended to brush your teeth with warm water. Oral experts recommend that people who suffer from severe tooth pain, tooth sensitivity, or recurring tooth sensitivity should choose an alkaline desensitizing toothpaste. The human oral environment is acidic. If the toothpaste is alkaline (PH value = 8), it will neutralize the oral environment and inhibit the growth of bacteria that cause inflammation. Toothpaste with desensitizing effect usually contains anti-allergic ingredients, which can help block external stimulation to the teeth and relieve tooth sensitivity symptoms.

By making some changes in your daily oral care and eating habits, you can reduce the exposure of dentin, thereby reducing tooth sensitivity and relieving sensitivity and pain.
