2. **Identifying the Options**: The options provided are:

- **Glossopharyngeal Nerve**: This nerve is involved in taste and swallowing but is not primarily associated with dental work.

4. **Conclusion**: The mandibular branch of the trigeminal nerve is commonly referred to as the "dentist's nerve" because it supplies the lower jaw and teeth. Therefore, the correct answer to the question is the **trigeminal nerve**.
