Mam I have twin babies.one of the baby got his lower 2 teeth erupted.and other one has not even got single tooth erupted in his mouth.Both are now 7.5 months old.kindly tell the normal eruption pattern.

A. The first teeth to erupt are the lower and upper central incisors, which erupt between the ages of 6 12 months. The next to erupt are the lateral incisors between 9-16 months, followed by the first molars from 13-19 months. Next, the cuspids (canines) erupt from 16-23 months.
