Today, let's talk about the little knowledge about baby teeth.The baby's baby teeth grow in batches, usually the front teeth erupt first, the left and right pairs erupt, and the lower teeth generally erupt earlier than the teeth of the same name in the upper jaw.If the baby has not grown teeth after the age of 1, you should see a doctor as soon as possible to check the cause in detail, to determine whether there is a local disease, or systemic disease, or developmental abnormalities.If the baby teething soon after birth, you should also go to the doctor in time. Because the teeth erupt prematurely and the roots are not fully formed, if the teeth are loose and fall out at this time, and are mistakenly inhaled by the baby into the trachea, it may cause life danger. In this case, it is recommended to remove them as soon as possible.
