What each tooth does
Kinds of teeth and common reasons to visit
Canines
The strong pointed teeth at the corners of the arch tear food and anchor the smile. Common reasons: decay, a chipped tooth, a tooth out of line.
Premolars
Sitting between the canines and the molars, they tear and crush food. Common reasons: cavities, sensitivity to hot and cold, a broken filling.
Molars
The broad back teeth grind food and take most of the chewing load. Common reasons: deep decay, pain when chewing, a cracked tooth or a worn filling.
Wisdom teeth
The last teeth to appear (usually between 17 and 25); with no room they stay trapped or come in crooked. Common reasons: swelling or pain, gum covering the tooth, pressure on the neighbour. Many people never grow all four, which is normal.

All 32 teeth - numbers and names
Each number has two digits: the first is the part of the mouth (1 upper right, 2 upper left, 3 lower left, 4 lower right), the second counts from the middle of the front (1 to 8). This is the international FDI system.

Children's baby teeth: the 20 baby teeth have their own numbers (51 to 85), so they are not on this chart. For a child's teeth see paediatric dentistry.
This chart is only to help you identify teeth - it is not a diagnosis. Not everyone has all 32 teeth (wisdom teeth that never came or were removed are common). For pain, swelling or any other problem, only an examination by the dentist can tell the cause and the treatment.
