my baby is 21 months old. his upper and lower molars have come on both the sides .total 4. but still his lower lateral front tooth has not come. he has only 2 lower teeth in front. 4 at top.

A. Hi usually all milk central and lateral incisor teeth erupt by 14-16 months maximum. consult with your nearest Pediatric dentist for proper clinical and radiographic examination of the unerupted milk teeth
