Serrula, in medicine, is a structure that develops between the teeth and the jaw. It's a small opening where saliva can be collected and used for cleaning the mouth.
In dentistry, it refers to any of several structures or structures that arise within the mouth during development. These include:
1. Dentin: The outer layer of tooth enamel, which is responsible for protecting the tooth from decay.
2. Dental pulp: A thin layer of tissue between the tooth and the jawbone
