Early tooth replacement in children is not a growth hormone deficiency. 1. Most children with growth hormone deficiency have significant differences from children of the same age after the age of 2; for example, well-proportioned limbs and a slightly fat abdomen; normal intelligence; backward bone age; a round face and a high-pitched voice; and possibly delayed sexual development, etc.; all of which have nothing to do with children changing their teeth early. 2. The child’s early tooth replacement may be due to genetic factors, such as parents or three generations of immediate family members in the case of early tooth replacement; may also be due to the child’s nutritional status, like to eat dietary fiber or coarse grains of the child due to the regular practice of chewing ability, there will be an early change of teeth; early tooth replacement and the lack of growth hormone does not have any clear correlation. If you are worried about your child’s growth hormone deficiency, you can go to the growth and development clinic of a regular medical institution and consult a professional doctor before deciding whether or not treatment is needed, and do not use medication without authorization to avoid adverse consequences.
