The jaw is made up of muscles that control the movement of the jaw. The muscles, however, can experience muscle fatigue just like any other muscles on the body.

Sensitive Teeth

Your teeth are made up of a tissue known as the enamel. It is the white outer layer of the tooth and the hardest substance in the body, stronger than even your bones. The enamel protects the dentine beneath it.

The dentine is sensitive to heat, cold, and pain and therefore needs the enamel to protect it. Grinding of teeth during sleep destroys the enamel.

Your child cringing in pain after biting something hot or cold is a sign that the enamel has been destroyed.

Chipped and Loose Teeth

The gums hold all the teeth firmly in place. A loose tooth is a clear sign that there has been damage to the gums.

Grinding of teeth can result in the weakening of the teeth at the root. This will, in turn, lead to you having loose teeth.

Sleep bruxism can also lead to chipping of the tooth, especially after the first line of defense, the enamel, is destroyed.
