Adult humans usually have 32 permanent teeth if all of their wisdom teeth are present, and 28 teeth if all four wisdom teeth have been removed or never developed.

How Many Teeth Do Adult Humans Have?

Quick Scoop

Most adults are designed to have a full set of 32 permanent teeth, split into 16 on the top jaw and 16 on the bottom. However, because many people have their wisdom teeth taken out (or they never fully come in), living with 28 teeth is extremely common and still considered normal.

The Basic Numbers

• With wisdom teeth: 32 teeth total (16 upper, 16 lower).
[5][1][3]
• Without wisdom teeth: 28 teeth total, which is extremely typical in modern adults.
[9][1][5]
• Childhood “baby teeth” set: 20 primary teeth before they are replaced by adult teeth.
[7][5]

Teeth Types in an Adult Mouth

• Incisors: 8 total (4 upper, 4 lower) – the flat front teeth for cutting food.
[1][5]
• Canines: 4 total – the pointed teeth used to tear food.
[5][1]
• Premolars: 8 total – used for crushing and tearing.
[1][5]
• Molars (including wisdom teeth): 12 total – main grinding teeth; the last 4 are the wisdom teeth.
[5][1]

Real-Life Variation

In real life, not everyone matches the textbook 32.

• Many adults have 28 teeth because their wisdom teeth were removed for crowding, decay, or prevention reasons.
[3][1][5]
• Some people are born without certain teeth (a condition called hypodontia) or lose teeth later due to decay, gum disease, or accidents.
[7][9]
• Others may even have extra teeth (supernumerary teeth), though this is less common.

Forum-Style Take

User A: “Wait, are we supposed to have 28 or 32 teeth? I’m missing my wisdom teeth so does that mean I’m not ‘complete’?”

User C: “I actually still have all 32 and my dentist just keeps watching my wisdom teeth every year. So yeah, both 28 and 32 happen.”[1][5]
