# Mouth Tool

{% @arcade/embed flowId="D0s6jYXASEAwbWdpK8pV" url="<https://app.arcade.software/share/D0s6jYXASEAwbWdpK8pV>" %}

The **Mouth** tool in Aperty allows you to enhance the appearance of the subject's smile by improving the brightness and color of the teeth while refining the look of the lips. It provides simple but effective options to ensure teeth and lips look natural, bright, and clean without over-editing.

* **Teeth Whitening**: Adjusts the overall whiteness of the teeth by removing yellow or discolored tones. Increasing this slider brightens the teeth, making them appear whiter and cleaner. Be careful not to overdo it, as teeth that are too white may look unnatural.
* **Teeth Brightening**: Enhances the overall brightness of the teeth by increasing their exposure and lightness. This effect gives the teeth a healthy glow, complementing the whitening adjustment. Increasing this slider makes the teeth stand out more, especially in low-light portraits or if the teeth appear dull.

{% hint style="info" %}
For natural results, use **Teeth Whitening** to subtly remove discoloration, followed by moderate **Teeth Whitening** to enhance overall appearance. Keep the adjustments balanced to avoid an overly processed look, ensuring the smile remains realistic and inviting.
{% endhint %}

* **Lips Blemish Removal:** Smooths out minor imperfections on the lips, such as dryness, cracks, or small blemishes, creating a healthier and more even appearance.
* **Lips Smoothing:** Softens the texture of the lips while maintaining natural details, reducing the appearance of fine lines and enhancing a polished look.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.aperty.ai/how-to-use-aperty/four-key-tools-categories/retouch-tools/mouth-tool.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
