Dental caries in 10-year-old children are commonly treated by filling cavities, root canal treatment, extraction of caries, etc. Depending on the severity of caries, parents are advised to bring their children to the clinic in time. 1. If the scope of caries is not large, it is necessary to remove the decayed tooth tissue, and then choose different artificial materials to fill the cavity in order to restore the shape and function of the tooth. 2. If the scope of the cavity is relatively large, even deep to the pulp and periapical tissues, the pulp and inflammatory tissues will be removed through root canal treatment, and necessary root canal anti-inflammation will be carried out, followed by filling of the root canal, and finally filling of the tooth. 3. If the carious cavity reaches the bottom of the pulp chamber or the inflammation at the root tip cannot be controlled, and the tooth has no value to be preserved, the decayed tooth will be considered to be extracted, and if it is a deciduous tooth, the eruption of the permanent teeth will be observed; if it is a permanent tooth, the tooth will be implanted or installed with a prosthesis according to the situation. Please follow the doctor’s instructions to standardize the treatment. Meanwhile, parents should advise their children to brush their teeth carefully, eat less sugary food, and reduce the frequency of sugary food, so as to reduce the total amount of caries-causing bacteria in the mouth and prevent the condition from worsening. Regular oral examination.
