Humans typically have 20 baby teeth in total, also called primary or deciduous teeth.

Quick Scoop

  • Total baby teeth: 20 (full set).
  • Top vs bottom: 10 on the upper jaw and 10 on the lower jaw.
  • Types included: incisors, canines, and molars (no premolars in baby teeth).
  • They usually start appearing around 4–7 months of age and complete over the next few years.
  • All 20 are eventually lost and replaced by about 32 permanent adult teeth.

Baby teeth may be temporary, but they’re important for chewing, speaking clearly, and holding space for future adult teeth.

TL;DR: Humans have 20 baby teeth before they are replaced by permanent adult teeth.
