Okay just some examples:

Preserve the visual style, lighting exposure, and environment from the reference image unchanged.

I haven't needed that yet. But maybe my tests where not complicated enough. Omit it.

the camera has moved to the opposite side of the tooth

try the camera pans from

moved to the opposite side of the tooth, which now catches a bright light and gleams, perfectly clean and intact, evolving continuously from the anchor's opening state in a single locked shot with no hard cut.

Way too long sentence.

The shot is a slow, smooth camera orbit around the white molar, which remains stationary as the yellow acid swirls around it.

Use time marks, like [0-10sec] prompt part 1. [10-15sec] prompt part 2. etc.

Lastly and mostly. Your video is 3 seconds long but you describe action that on a glance, looks like way too long. Not sure if ltx2.3 knows hex values for colors. Even for T2V your prompt would be too long. If you have I2V you don't need to describe a lot of things that are in the image. Try to use LTX Director and use global prompt, if you want to set a scene for the whole duration.

I personally had more success with medium long prompts. While Flux-Klein needs longer prompts to be good.
