A child’s teeth growing out of the side of the gums may be caused by ectopic eruption of permanent teeth, which will require prompt removal of the milk teeth. It may also be a supernumerary tooth, which can be removed. If a child’s milk teeth do not fall out in time, occupying the space for permanent teeth to grow, it will lead to permanent teeth erupting in an incorrect position. In this case, the baby teeth can be removed in time and the permanent teeth can usually be adjusted to the correct position on their own. If they are not removed in time, the permanent teeth will continue to grow and can be corrected at a later stage with orthodontic treatment. In addition, the teeth grow out from the side of the gums may also be polyposis, polyposis is usually related to the development of tooth germ, heredity, genetic mutation and so on. It may affect the aesthetics of the teeth and make them untidy, and may also cause pressure on the roots of the teeth, and the supernumerary teeth can be extracted when necessary. It is recommended to consult a professional doctor for reasonable treatment under the doctor’s guidance.
