What is Teeth and Dental Health?
Within Biology, which covers cells, the human body, genetics, evolution, plants and ecosystems: the science of living things, this topic explains Teeth and Dental Health. Biology topics show how living things work, from the cell up to whole ecosystems, with models you can explore step by step.
Check that you can explain Teeth and Dental Health in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Teeth and Dental Health helps you explain how living things stay alive and respond to their surroundings, which is central to biology exams.
Teeth and Dental Health in detail
Humans have four types of teeth: incisors for cutting, canines for tearing, premolars and molars for grinding. A tooth has enamel (hard outer layer), dentine (softer inside), and pulp (nerves and blood vessels). Humans have two sets: 20 milk teeth and 32 permanent teeth.
Tooth decay occurs when bacteria in plaque feed on sugars and produce acid that dissolves the enamel. Prevention includes brushing with fluoride toothpaste, flossing, reducing sugary food and drinks and regular check-ups. Fluoride strengthens enamel. Gum disease occurs when plaque builds up at the gum line.
