Why are Baby Teeth so Spaced Out?

Published in Dental Development 2 mins read

Baby teeth are intentionally spaced out to prepare for the arrival of larger adult teeth. The gaps between baby teeth are crucial for the proper development of a healthy smile.

The Purpose of Spacing

How Spacing Helps:

  • Space for Adult Teeth: The primary reason for the gaps is to provide enough space for the larger adult teeth to erupt correctly. Baby teeth are significantly smaller than adult teeth; without the spaces, there wouldn't be enough room for adult teeth to come in straight. As stated in the reference, these "gaps or spaces are what we want! Baby teeth are very small in size in comparison to the adult teeth counterparts. By having gaps in between each baby teeth, the extra space allows for the larger adult tooth to erupt into its normal place."


Consequences of Insufficient Spacing

If baby teeth were tightly packed together, several issues could arise when adult teeth start to emerge:

  1. Crowding: The adult teeth would likely be crowded and misaligned. This can lead to problems with bite, chewing, and jaw development.
  2. Impacted Teeth: If there is not enough room, adult teeth might not be able to erupt fully.
  3. Orthodontic Needs: Crowding often requires orthodontic treatment like braces or Invisalign.


Table: Baby Teeth vs. Adult Teeth

Function Prepare the way For life
Purpose of gaps Allow room for adult teeth Less room needed


What to do

Here's a simple checklist for parents to follow:

  • Regular Checkups: See your dentist regularly for checkups.
  • Good Dental Hygiene: Teach children to brush and floss.
  • Address Issues Early: Consult a dentist if you notice early signs of misalignment or overcrowding.


It's important to understand that the spacing of baby teeth is a natural and necessary part of dental development. This natural spacing provides room for the larger adult teeth to grow into their correct positions, contributing to a healthy and properly aligned smile in the long run.
