Question

A 29-month-old girl has had a total of 16 teeth since she was 18 months old, and there are still 4 teeth that have not emerged. She has previously been tested for trace elements and found to have a slight zinc deficiency, which has been supplemented. Is this situation normal? What should be done if the teeth still do not emerge? The baby currently has no other deficiencies. Please provide an expert answer; thank you.
