Question
The baby is already 10 months old, but no teeth have emerged yet, and there is a slight delay in development. After a hospital check-up, all growth indicators are normal. However, parents are worried about the baby’s delayed tooth eruption and want to know if further examination or treatment is necessary.
Answer
The delayed eruption of primary teeth in babies may be caused by calcium deficiency, which is known as rickets due to vitamin D deficiency in medicine. It is recommended that parents often take the baby outdoors for activities to utilize sunlight exposure to promote the production of endogenous vitamin D in the skin. At the same time, consider adding fish liver oil and other foods rich in vitamin D. If the baby shows delayed tooth eruption or smaller teeth, special attention should be paid to their calcium intake.
