Soreness of the teeth while chewing is a very common condition. Tooth soreness may be due to infectious diseases of the tooth caused by bacteria in the mouth and destruction of the protective layer. Tooth soreness is mostly seen in inflammation that occurs in the central pulp of the tooth, where the gums contain nerve endings that are very sensitive to pain. Inflammation of the pulp may be caused by tooth decay, trauma and infection. All of these abnormal irritations can lead to irritation of the nerve endings and cause soreness in the teeth. In more severe cases, severe pain can occur. Stress and hot and cold stimuli can cause soreness and discomfort in the teeth. Eating excessively hard foods, cold and hot stimulating foods can cause the pulpal nerve endings of the teeth to be irritated. This is mainly seen in unhealthy teeth with excessive damage to the enamel. These teeth lack the protection of enamel, making them less tolerant of these stimuli and more prone to tooth soreness. In order to reduce the inflammation of the teeth and to reduce the destruction of the protective layer of the teeth, it is necessary to pay attention to the cleaning of the teeth and to maintain good hygiene habits in daily life. The appearance of teeth when eating indicates that the teeth themselves have developed unhealthy problems. When this symptom occurs, it is necessary to go to the regular hospital for timely consultation. To avoid more serious tooth decay problem, timely treatment should be given.
