Your jaw performs an important role in helping to balance and stabilize your head. The jaw muscles are the largest muscles in the head, and they partner with other muscles to keep the head in its proper position. In this task, they use the jaw as a stable anchor point.
When you lose teeth, your jaw becomes unstable. This is often reflected in the way you hold your head, which can tilt left, right, or downward.
Ideally, dentures should make your jaw a stable anchor again. Unfortunately, most dentures just don’t, which can make the head tilt even more severely than without dentures.
