Do you know the different types of teeth and their function? How many primary teeth typically develop? How many permanent teeth develop? Nursing students and healthcare majors must take anatomy and physiology in college. It is also useful to have a basic understanding of teeth anatomy because some buccal medications may require placement above a certain tooth or in a certain arch.
Take the types of teeth anatomy quiz below to test your knowledge. Before taking this quiz, you might want to watch our types of teeth video or review our types of teeth anatomy notes.

Types of Teeth Anatomy Quiz
1. How many teeth typically develop in the first dentition (primary teeth)?
a. 30
b. 18
c. 20
d. 26
The answer is c, 20. There are typically 8 incisors, 4 canines, and 8 molars in the primary dentition, which makes 20 teeth in total.
2. How many teeth typically develop in the permanent dentition in a complete set?
a. 30
b. 32
c. 24
d. 28
The answer is b, 32. There are 8 incisors, 4 canines, 8 premolars, and 12 molars, which makes 32 teeth in a complete set.
3. The primary teeth (baby teeth) are made up of all types of teeth except:
a. Molars
b. Incisors
c. Canines (Cuspids)
d. Premolars (Bicuspids)
The answer is d, premolars. Premolars do not typically appear with the first dentition (primary teeth).
4. Which statement is incorrect concerning incisor teeth?
a. Both primary teeth and permanent teeth contain 8 incisors
b. Incisors typically have only one root
c. The main function of incisors is to grind food
d. Incisors assist with speech
The incorrect answer is c. The main function of incisors is to cut off pieces of food with its incisal edge. The molars and premolars grind and chew the food.
5. Which teeth are distal to the lateral incisors, contain only one cusp, and are used to pierce and tear off food?
a. Canines
b. Cuspids
c. Eyeteeth
d. All of the above
The answer is d, all of the above. Cuspids, also called canines or eyeteeth, pierce food, have only one sharp cusp, and sit distal to the lateral incisors for both the primary and secondary dentition.
6. What is another name for the upper dental arch?
a. Maxillary arch
b. Mandibular arch
c. Golden arch
d. Incisal arch
The answer is a, maxillary arch. The upper arch attaches to the maxilla, which is the upper jawbone.
7. What is another name for the lower dental arch?
a. Maxillary arch
b. Mandibular arch
c. Golden arch
d. Incisal arch
The answer is b, mandibular arch. The lower jaw is the mandible, and the name for the lower arch is the mandibular arch.
8. Which statement is false regarding premolar teeth (bicuspids)?
a. The main function of premolars is to grind or chew food
b. Premolars typically have at least two cusps, but may have 3 or 4
c. Premolars always have only one root
d. Premolars are absent in the primary dentition
The false answer is c. Premolars typically have one root, but they may have 2 or 3 root, especially on the maxillary first premolar.
9. How many molars are typically present in the first and second dentitions?
a. 8 in the primary dentition; 12 in the permanent dentition
b. 4 in the primary dentition; 10 in the permanent dentition
c. Zero in the primary dentition; 8 in the permanent dentition
d. 12 in the primary and permanent dentitions
The answer is a. There are 8 molars in the primary (baby) teeth, and 12 in a complete set of permanent teeth.
10. Which statement is false regarding the third molars?
a. Third molars are typically only present in the permanent dentition, not the primary dentition
b. Third molars are also called wisdom teeth
c. Third molars may fail to erupt in many individuals
d. Third molars typically have one sharp cusp and one root
The false statement is d. Third molars tend to have 4-5 cusps and 2-3 roots.
11. Which quadrant number is the mandibular right quadrant?
a. Quadrant 1
b. Quadrant 2
c. Quadrant 3
d. Quadrant 4
The answer is d, quadrant 4. The maxillary right is quadrant 1, and the numbers flow clockwise from there when you look at it from the anterior view. Maxillary left is quadrant 2, mandibular left is quadrant 3, and the mandibular right is quadrant 4.
