People could be grinding their teeth without even knowing it and this could be causing them to have a range of problems including headaches, toothache or a sore jaw. 
My Local Health reported bruxism – as the problem is technically known – happens more often than people realise, with many grinding their teeth during their sleep.

“Beyond causing discomfort, grinding can eventually damage dental restorations and possibly loosen teeth. It can also cause damage to the temporomandibular joints,” the article noted.
The temporomandibular joints are the ones which connect a person’s jaw to their skull.
