Detailed Answer:
Hi
Welcome to the HCM
I completely understand your concerns but don't worry. Primary teeth eruption shows wide variations in kids. But most of the kids get all their 20 primary teeth by the age of 3 years.

Sometimes delay can be due to premature birth, hypothyroidism, rickets, hypoparathyroisism. So, I would recommend you to go for the following laboratory work up if the teeth do not erupt (even after 4 months of first tooth eruption) to rule out any of these:

-TSH, FT4, FT3 to rule out thyroid dysfunction
-25(OH)D3, S. Calcium, S. Phosphorus, PTH to rule out any rickets, hypoparathyroidism

You may upload the reports for my reference. Also, ensure a regular healthy diet and fluids.

Hopefully this will help you.
Take care
