FAQs on Arrangement of Teeth and Different Types of Teeth Video Lecture - Science Class 7

1. What is the arrangement of teeth in the mouth?
Ans. The arrangement of teeth in the mouth is known as the dental arch. It consists of two arches, the upper arch (maxillary arch) and the lower arch (mandibular arch), with teeth arranged in a specific pattern to form the dental occlusion.
2. What are the different types of teeth found in the mouth?
Ans. There are four main types of teeth found in the mouth: incisors, canines, premolars, and molars. Incisors are the front teeth used for cutting, canines are pointed teeth used for tearing, premolars are located between canines and molars and are involved in chewing and grinding, and molars are the back teeth used for grinding and chewing.
3. How many teeth are there in the adult human mouth?
Ans. In the adult human mouth, there are typically 32 teeth. This includes 8 incisors, 4 canines, 8 premolars, and 12 molars (including 4 wisdom teeth). However, it is common for some individuals to have fewer teeth due to extraction or congenital absence.
4. What is the purpose of each type of tooth in the mouth?
Ans. Each type of tooth in the mouth serves a specific purpose. Incisors are used for biting and cutting food, canines are for tearing and grasping, premolars assist in chewing and grinding, and molars are primarily responsible for crushing and grinding food before swallowing.
5. What are the consequences of misaligned teeth?
Ans. Misaligned teeth, also known as malocclusion, can lead to various consequences. These may include difficulties in biting and chewing, speech problems, increased risk of tooth decay and gum disease, jaw pain or temporomandibular joint disorders, and even self-esteem issues due to the appearance of the smile. It is advisable to consult a dentist for appropriate treatment options if misaligned teeth are causing any problems.
