There are 32 teeth in the human mouth, including the wisdom teeth at the back that most people have removed. But how many of them do we seriously need? This question has exercised dentists since the dawn of the NHS with its cash-limited budget for treatment.
What is the Total Number of Teeth in the Mouth? An adult person who has all his or her adult teeth should have a total of 32 teeth. These include 8 incisor teeth (four upper and four lower), 4 canine teeth (two upper and two lower), 8 premolars (four upper and four lower), and 12 molars (six upper and six lower). The 4 wisdom teeth are among the molars. A child, who is younger than 6 years old, usually has 20 deciduous teeth. These include 8 primary incisor teeth (four upper and four lower), 4 primary canine teeth (two upper and two lower) and 8 primary molars (four upper and four lower).
