Teeth Flashcards
What are the four types of teeth and their primary functions?
The four types of teeth are incisors (for cutting or slicing food), canines (for gripping and holding food), premolars (for chewing and grinding food), and molars.
How many of each type of tooth are typically found in the mouth?
There are usually 4 incisors, 2 canines, 2 premolars, and 3 molars on each side of the mouth, totaling 5 premolars and molars per side.
What is dentine and its role in the tooth structure?
Dentine is a bone-like structure underneath the enamel. It contains cytoplasm and tubules running from the pulp cavity, providing the underlying structure and support for the enamel.
Describe the pulp cavity.
The pulp cavity is the hollow middle part of the tooth, containing blood vessels and nerves. These supply the tooth with nutrients and oxygen.
What is cement in the context of tooth anatomy?
Cement covers the root of the tooth. Fibres grow out of the cement and attach the tooth to the jaw.
What is enamel and its significance?
Enamel is the hardest substance made by animals, covering the tooth. It provides a tough surface for biting and chewing. However, it can be damaged by acids.
What is plaque and how is it formed?
Plaque is a sticky coating made from leftover food particles, saliva, and bacteria. Bacteria in the plaque respire sugars, creating acids that can damage teeth.
