HOSA Dental Terminology Practice

What is meant by 'Eruption' in relation to teeth?

1. Loss of a primary tooth

2. Movement of the tooth as it emerges through surrounding tissue

3. Growth of periodontal tissues

4. A type of tooth discoloration

The correct answer is: Movement of the tooth as it emerges through surrounding tissue

The term 'eruption' in relation to teeth specifically refers to the movement of a tooth as it emerges through the surrounding tissue. This process typically involves a combination of biological changes and physical movements that allow a tooth to break through the gum tissue and enter the oral cavity. Eruption can be categorized into primary (baby teeth) and permanent teeth, each following a specific timeline and sequence as part of dental development. Understanding the process of eruption is crucial for various aspects of dental health, including monitoring the development of a child's teeth and recognizing any abnormalities that may affect oral health. It is a natural part of the growth process where teeth ascend through the jawbone and gums until they are fully visible in the mouth, ready for function. This is not related to the loss or discoloration of teeth, nor does it pertain to the growth of periodontal tissues.
