Most adults have 32 teeth if all their wisdom teeth are present, but many people function normally with 28 teeth after wisdom teeth removal.

Quick Scoop: How many teeth are in your mouth?

  • As a baby/child : 20 “baby” (primary) teeth.
  • As an adult with all teeth: 32 permanent teeth (16 top, 16 bottom).
  • As an adult without wisdom teeth: commonly 28 teeth (14 top, 14 bottom).

Mini breakdown by type (adult full set)

  • 8 incisors (front cutting teeth).
  • 4 canines (pointed, tearing teeth).
  • 8 premolars (for chewing and grinding).
  • 12 molars, including 4 wisdom teeth at the very back.

So the answer to “how many teeth are in your mouth?” depends a bit on age and wisdom teeth:

  • Child: about 20.
  • Adult: usually 28–32, most often 32 in textbooks but 28 in everyday reality after wisdom teeth removal.

TL;DR:

  • Baby mouth: 20 teeth.
  • Adult mouth: 32 teeth if you keep all wisdom teeth, 28 if they’re removed (both are normal).
