At Morrow, Lai & Edwards Pediatric Dentistry , we know teething patterns vary greatly from child to child—some don’t have any teeth by their first birthday, while others have a mouthful by then. Experts, however, including our friends at the American Academy of Pediatric Dentistry, do recommend that children have their teeth checked by their first birthdays.
Your child will have 20 baby teeth, which will later be replaced by permanent teeth. A baby’s first tooth can come in as early as 3 months or as late as 1 year of age, however primary teeth usually begin to break through the gums when a child is about 6 months old. Most kids have all of their primary teeth by the time they are 3 years old.
The most important thing is not to worry if your toddler’s pearly whites don’t look perfect as they come in—baby teeth come in all shapes, sizes, and slants. Teeth generally appear one at a time over a period of months, and often—but not always—in this order: First the bottom two middle teeth, then the top two middle ones, then the ones along the sides and back. (They may not all come in straight, but don’t worry—they usually straighten out over time.) Besides crooked teeth, your child may experience crowded or spaced-out teeth, missing teeth, supernumerary (too many) teeth and even discolored teeth.
