Tooth Eruption Guide–When Will My Children’s Teeth Come In and Fall Out?

January 13, 2024 ABC Children's Dentistry

Did you know that your baby’s teeth start forming before they are even born? It’s true! Although you can’t see them during the first six months, the teeth are there, waiting to emerge beneath the gums.

Many parents wonder when their children’s teeth will emerge and when they will fall out.  Be aware that the timing of tooth eruption varies widely, so talk to your pediatrician if you are concerned that your baby’s teeth have not yet come in.

Here is a comprehensive guide to help you estimate the times when teeth will be arriving–or leaving!

Primary Incisors (Baby Front Teeth)

Typically, your baby’s front two bottom incisors will be the first to come in at around 6 months of age. About 2 months later, the top two incisors will follow. It is common for babies’ teeth to erupt in pairs. Once you notice a tooth emerging, it is important to start brushing it with a soft infant toothbrush.

Primary Lateral Incisors

The lateral incisors, which are located right beside the front incisors, will be the next to appear. You can expect these teeth to erupt around 9 months of age. Often, the top four teeth (both central and lateral incisors) will come in around the same time. It is a good idea to schedule your baby’s first dental visit by the time he or she turns one, so that your pediatric dentist can examine the new teeth.

First Set of Primary Molars

Following the incisors, the first molars will begin to emerge. Usually, babies get their molars before their canines, creating a temporary space between the front four teeth and the back teeth. The first molars usually erupt around 13 months of age.

Primary Canines

The canine teeth are responsible for tearing food and will help your baby eat more textured foods. These teeth generally erupt around 16 months.

Second Set of Primary Molars

The second set of molars is sometimes referred to as the “two-year molars” because they typically emerge around your baby’s second birthday.

First Permanent Molars

Your child’s first adult teeth, known as permanent molars, will begin to erupt around the age of 6. At this stage, many children may not have the dexterity to reach the back of their mouth to brush these important teeth. It is important to assist with brushing, especially at night, until the child reaches the age of 8.

When Will My Baby’s Teeth Start Falling Out?

Generally, your child’s baby teeth will fall out in the same order that they emerged. The first tooth is typically lost around the child’s 6th birthday. The process of losing baby teeth usually continues until the child is about 12 or 13 years old. As permanent teeth take their place, it is important to keep up with good brushing and oral hygiene, including regular trips to the dentist.
