Children who have not grown new teeth after tooth extraction are mainly caused by permanent teeth not yet erupted, permanent teeth blocking eruption or congenital absence of permanent teeth.
1. Permanent teeth do not come to the eruption time: the eruption time of permanent teeth has a certain pattern, therefore, after the loss of milk teeth, if the permanent teeth do not come to the eruption time, they will not be erupted; this kind of symptom generally does not require special treatment, and can be left to its own eruption.
2. Permanent tooth eruption obstruction: If milk teeth are extracted prematurely due to periapical disease or dental trauma, the gum tissue at the missing teeth will become thick and tough due to friction from food, which will prevent the normal eruption of permanent teeth; at this time, it is necessary to seek medical treatment for dental eruption aid, which is to cut open the gum tissue in order to take advantage of the normal eruption of permanent teeth.
3. Congenital absence: permanent teeth can also appear congenitally with the above symptoms, and must be treated with gap maintenance therapy to maintain the gap of the missing teeth; and wait until adulthood for orthodontic or restorative treatments.
