Answer:
The disadvantages of have a fixed lower jaw are as follows:
> You cannot chew food properly, as food chewing involves the movement of both upper and lower jaws.
> You are unable to open your mouth wide.
> You may have difficulty in talking and eating, because the lower jaw movement is involved in both.
Both the jaws help in facial movement and ingestion. So a fixed lower jaw can affect these functions.
