About Primary Teeth and Dental Anatomy

As you learn about primary teeth, you will hear terms like “canines,” “incisors,” and “eruption” at the dentist office. Make sure to learn these basic terms which will help you better understand your child’s dental milestones. Here’s a breakdown of key dental terms, eruption timelines, and how to care for those first tiny teeth.

What Are Primary Teeth?

Primary teeth, also called baby teeth or deciduous teeth, are the first set of teeth to emerge. These 20 small teeth play a big role in your child’s oral development, helping with chewing, speech, and guiding permanent teeth into place. Click here to book a dental appointment.

Each arch (upper and lower jaw) contains:

  • 4 incisors (2 central, 2 lateral)
  • 2 canines
  • 4 molars

When primary teeth are ready to fall out, the process is called exfoliation, making room for permanent teeth.
