The front teeth on generated video are too big and how to deal with it?

In fact, the character in the original video did not reveal his upper front teeth when speaking, but only his lower front teeth. But the synthesized video generated an exaggerated upper front teeth, so it seemed very unnatural. Whether there is a way to adjust the size of the upper front teeth.
