If there is no gap between the milk teeth and there is no deformity or misalignment, it can be left untreated and observed for the time being, but if there is deformity or misalignment, you should go to the hospital stomatology department in time for consultation. Milk teeth are gradually lost and replaced by permanent teeth from the age of 6 to 7 to 12 to 13 years old, and the jawbone will develop, so there will be gaps between the teeth, and there is no need for special treatment for milk teeth without gaps. When the permanent teeth appear to be malformed and misaligned, and there is no gap, they can be corrected through orthodontics to improve the malformation or misalignment of the teeth. At the same time, oral hygiene should be paid attention to in daily life to avoid food residues, resulting in the occurrence of dental caries.
