The child’s teeth are black and rotten with a hole, usually caused by dental caries, treatment measures should be decided according to the specific situation. If minor caries can be relieved by changing medication and filling on time; more serious caries accompanied by localized infection requires root canal treatment and extraction treatment if necessary. 1. If your child suffers from minor caries and the above symptoms appear, you need to go to the hospital dentist in time, change the local medicine regularly to eliminate the infected lesions, and then carry out local filling treatment to help your child improve the discomfort symptoms and promote early recovery. 2. If the degree of tooth damage is more serious, leading to pulpitis or apical periodontitis, etc., it is recommended to follow the doctor’s instructions for root canal treatment. It needs to be carried out by a professional dentist and can quickly improve the symptoms of toothache. In particular, after root canal treatment for caries in baby teeth, the baby teeth will be replaced as the permanent teeth gradually erupt, providing a complete cure. 3. If the permanent teeth have serious necrosis, infection, etc., it is necessary to consult the doctor in time, and the doctor will carry out the extraction treatment to completely improve the discomfort symptoms. You need to go to a regular dentist to ensure that the treatment is safe. Parents are advised to strengthen their children’s dental care, develop a good habit of brushing their teeth every day, and rationalize their diet to avoid the above symptoms.
