## **Core Concept**
The lymphatic drainage of the teeth involves a network of lymph nodes that help in filtering out bacteria and other pathogens. The lymphatic vessels from the teeth drain into specific groups of lymph nodes in the head and neck region.

## **Why the Correct Answer is Right**
The lymph from the teeth primarily drains into the submandibular lymph nodes. From there, it can further drain into the deep cervical lymph nodes. The submandibular nodes are a primary site for lymphatic drainage of the anterior parts of the mouth, including the teeth.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Submandibular nodes are indeed involved in the lymphatic drainage of the teeth, making this option incorrect as an "except" choice.
- **Option B:** Deep cervical nodes receive lymph from the submandibular nodes and are also involved in the drainage pathway, making this option incorrect.
- **Option C:**
- **Option D:** The correct answer is related to the specific drainage pattern of the teeth.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the lymphatic drainage of the teeth and gums is primarily to the submandibular lymph nodes, and from there to the deep cervical nodes. This pattern is crucial for understanding the potential spread of dental infections.

## **Correct Answer:** D. Retropharyngeal nodes.
