Differences Between Primary & Secondary Teeth

Differences Between Primary & Secondary Teeth

As children grow and lose their baby teeth, changes occur in the makeup of their teeth. These differences make primary teeth more susceptible to rapid tooth decay.

Differences between primary and permanent teeth include:

  • primary teeth have shorter clinical crowns
  • primary teeth have thinner layers of enamel and dentin
  • the roots of front primary teeth are narrower
  • Compared to their crowns, primary tooth roots are Longer and more slender

Starting children out with proper oral health can benefit them through their entire lifetime. Here are some helpful hints:

  • Your child's first visit should happen right around his or her first birthday (approximately 6 months after eruption of first tooth)
  • Primary teeth typically start to erupt around 6 months. All 20 primary teeth should be completely in by age 3.
  • Children begin to lose primary teeth between the ages of 5 and 6. This process lasts typically until the child is 12 or 13 years old when most permanent teeth have erupted.
  • Consider sealants on your child's teeth to help prevent cavities.
