I am rendering a Roblox character in Blender to make a GFX. I seem to be continuously running into this issue, no matter how many times I re-render the image. How do I fix this?

are you using a jpeg as the mouth's texture, or as render output?

Anyway, jpeg is a really harsh lossy picture format. There is always a quite noticeable loss with it.

I recommend you read the Blender Manual's page about the Supported Graphics Formats. Starting by this very simple yet quite true Hint:

If you are not interested in technical details, a good rule of thumb for selecting output formats for your project is:

Use OpenEXR
if you intend to do compositing or color grading on these images.
Use PNG
if you intend on-screen output or encoding into multiple video formats.
Use JPEG
for on-screen output where file size is a concern and quality loss is acceptable.

All these formats support compression which can be important when rendering out animations.

TL;DR : don't use jpeg if you care about quality.
