The Evolution of Teeth: From Baby to Adulthood

Learn about dental development stages from infancy to adulthood and when to schedule your child's first orthodontic evaluation.

The Evolution of Teeth: From Baby to Adulthood

Understanding how teeth develop from infancy to adulthood helps parents know what to expect and when to seek orthodontic evaluation.

Baby Teeth (Primary Dentition)

Timeline

  • 6-10 months: First teeth emerge (usually lower central incisors)
  • 12-18 months: First molars appear
  • 16-22 months: Canines emerge
  • 2-3 years: Complete set of 20 baby teeth

Important Role

Baby teeth:

  • Hold space for permanent teeth
  • Guide jaw development
  • Enable proper nutrition
  • Support speech development

Mixed Dentition (Ages 6-12)

This transition period is crucial for orthodontic evaluation:

  • Age 6: First permanent molars appear behind baby teeth
  • Ages 6-8: Lower and upper front teeth replaced
  • Ages 9-12: Remaining teeth gradually replaced
  • Ages 11-13: Second molars emerge

Permanent Dentition

Adults have 28-32 teeth:

  • 8 incisors (front teeth)
  • 4 canines
  • 8 premolars
  • 8-12 molars (including wisdom teeth)

When to Consult an Orthodontist

The American Association of Orthodontists recommends:

  • First evaluation at age 7
  • When permanent teeth begin appearing
  • If baby teeth are lost very early or late
  • If there are spacing or crowding concerns

Common Developmental Issues

  • Early tooth loss: Can cause shifting
  • Delayed eruption: May indicate impaction
  • Crowding: Often visible by age 7
  • Crossbite: Should be treated early

Why Early Evaluation Matters

At age 7, an orthodontist can:

  • Predict future development
  • Identify problems early
  • Plan interceptive treatment if needed
  • Avoid more complex treatment later
