at what age do most babies start teething
When to Expect Teething to Begin. Most babies' teeth begin to erupt between the ages of 4 to 6 months, though for some it may be earlier or later, Dr. Josen says. And no matter what Grandma says, when your child's first tooth pops in, it has nothing to do with smarts. The age the baby cuts his or her first tooth depends on family history of teething and nothing more, says Jill Lasky, D.D.S., a pediatric dentist at Lasky Pediatric Dental Group in Los Angeles.
