Sore teeth from eating acid are mainly a symptom of tooth sensitivity. If it is caused by tooth loss, it can be relieved by filling the tooth. If the tooth is sensitive, it can be treated by desensitization methods, there are mainly some desensitizing toothpastes and fluoride preparations in the clinic, and laser desensitization methods can also be considered. Patients can use desensitizing toothpaste at home to deal with the usual tooth pain. There is no particularly good way to stop the pain in time, and tooth soreness, a sensitive condition, is a slow process of treatment. Patients who have sore teeth without a good and timely pain relief method can go to a nearby dental specialty hospital for timely medical attention.
