baby teeth timing parents

Posted .

There are many areas new parents tend to worry about with their infants, and the growth of baby teeth is a good example. Baby teeth grow in at different precise times for different children, and some parents who have had previous children or spoken to other parents may be concerned if their child’s timing differs too much.

At Children’s Crossing Pediatric Dentistry, we offer a variety of children’s dentist services, from helping with your child’s first dental visit to informing you of several important facts when it comes to their baby teeth growing in. To keep you from stressing about early growth or other care for baby teeth, here’s a primer on each of the important tooth areas that will grow in for your infant, plus the ranges during which to expect them.


The first teeth that will generally erupt, or break through the gum line and begin growing in visibly, will be those known as incisors. These are small-yet-sharp teeth designed to help infants begin chewing as they move away from only consuming soft foods. Children will chew early solids using a combination of these incisors and their back gums.

Here are some general ranges for the appearance of various incisors in children:

  • 6-10 months: Lower central incisors will begin to come in – these are the bottom front teeth, and usually the first to erupt.
  • 8-12 months: Upper incisors begin to show up within this range.
  • 9-13 months: Upper lateral incisors, the ones located on each side of the front teeth, may arrive.
  • 10-16 months: Lower lateral incisors are usually the last incisors to erupt.

Early Molars

Many parents prepare themselves in advance for teething, which generally takes place when the first molars are beginning to grow in. Teething may lead to some pain and crying in children, but the molars that grow in contain flat surfaces that help them grind and chew solid foods and expand their diet. Their age ranges go as follows:

  • 13-19 months: First upper molars generally begin to erupt.
  • 14-18 months: Lower first molars begin to erupt.

Cuspids (Canines)

Those following along will be wondering about the space between the incisors and early molars, and these are filled by cuspids, or canines. These are strong, pointed teeth that allow for gripping and breaking of food, and they grow in within the following ranges:

  • 16-22 months: Two upper canines begin to grow in between incisors and molars.
  • 17-23 months: Two lower canines also begin to appear.

Second Molars

Finally, second molars will erupt in the bottom of the mouth between 23 and 31 months, while upper second molars will grow in by the 25-to-33 month range. By age three or earlier in most cases, your child should have their full set of 20 baby teeth, which will aid them with everything from chewing and swallowing to facial development, speech patterns and preparation for adult teeth down the line.
