Chimpanzees have a total of 32 teeth in their mouth. This is the common dental formula for all apes as well as all Old World monkeys. This comes from their 2.1.2.3 dental formula. The formula is the number and type of teeth found on one side of one jaw.

This inorganic material is mainly composed by a calcium phosphate related to the hexagonal hydroxyapatite, whose chemical formula is Ca₁₀(PO₄)₆·2(OH) ¹.

Humans have heterodont dentition with four different types of teeth: Incisors (I), Canines (C), Premolars (PM) and Molars (M). Arrangement of teeth in each half of the upper and lower jaw in the order I, C, PM, M is represented by a dental formula, which in humans is 21232123.

Explanation: The dental formula for a modern human adult is 2:1:2:3 in each quadrant: two incisors, one canine, two premolars, and three molar, for a total of 32 adult teeth. There is some variation in this number, as the third molar (also known as the Wisdom Tooth) is not present in all modern human adults.

Counting the number of each tooth type in one of the maxillary halves produces the following dental formula: 2I, 1C, 2P, 3M. This means that in any quadrant of the human mouth, two incisors, one canine, two premolars, and three molars can be found.

All Old World monkeys, apes, and humans share this 2.1.2.3 dental formula. This not only sets us apart from New World monkeys and prosimians, but it also reflects the evolutionary closeness of the Old World anthropoid species.

The dental formula of Dog

Dogs are omnivores, which means they consume both plants and animals. The dental formula for Dog is: 2 x (3142 / 3143) = 42 teeth (6 incisors 2 canine 8 premolars and 4 molar) / (6 incisors 2 canine 8 premolars and 6 molar) = 42 teeth.

How many adult teeth do you have? Most adults have 32 teeth, once all of their teeth have come in. This will most likely happen by the time a person has reached between the ages of 12 and 14. Some children may not have lost the last of their baby teeth by this age, but this is an uncommon occurrence.

What is the commonly used dental formula? ›

In the form I.C.P.M. , the dental formula is calculated by counting the number of Incisors, Canines, Premolars, and Molars. For example, the upper jaw's dental formula is 2.1.2.3, while the lower jaw's formula is 2.1.2.3. (I2 – C1 – P2 – M3) / (I2 – C1 – P2 – M3) / (I2 – C1 – P2 – M3) / (I2 – C (I2 – C1 – P2 – M3).

There are generally 40 teeth in the mouth of an adult horse. The so-called dental formula for each hemi-arch includes: 3 upper and 3 lower incisors, 1 canine above and one below, 3 premolars above and 3 below and finally an equal number of molars. The total, multiplied by 2, gives the result of 40 teeth.

Among permanent teeth, 16 are found in the maxilla and 16 in the mandible, for a total of 32. The dental formula is 2.1.2.32.1.2.3. Permanent human teeth are numbered in a boustrophedonic sequence.

The dental formula is defined as the number of teeth present in the half of the upper jaw and half of the lower jaw. The dental formula of adult human teeth is 2123/2123. It means that there are 2 incisors, 1 canine, 2 premolars and 3 molars in each half of the upper and lower jaw.

The permanent dentition consists of 32 teeth in total, with the dental formula 2123 (or 2123/2123), indicating two incisors, one canine, two premolars, and three molars in each quadrant.

Today, humans possess 32 permanent teeth with a dental formula of 2.1.2.32.1.2.3. This breaks down to two pairs of incisors, one pair of canines, two pairs of premolars, and three pairs of molars on each jaw.

The Dental Formula of Adults

There are 16 teeth in each arch and eight in each quadrant. Incisors are the eight middlemost teeth (4 up, 4 down) both on the upper and lower jaw. Canines are pointed teeth which are another four teeth (2 up, 2 down) just outside the incisors.

The dental formula expresses the arrangement of teeth in each half of the upper jaw and the lower jaw. Humans below 17 years of age normally do not have the 3rd molar i.e. wisdom teeth. So the dental formula in an adolescent is 2,1,2,2 / 2,1,2,2 and the total number of teeth is 28.

Among permanent teeth, 16 are found in the maxilla and 16 in the mandible, for a total of 32. The dental formula is 2.1.2.32.1.2.3. Permanent human teeth are numbered in a boustrophedonic sequence.
