Between 8-10% of the population are thought to grind their teeth regularly. This condition is called “bruxism.” Many people grind their teeth or go through a phase of jaw-clenching at some time in their lives, but a sizeable percentage of Australians grind or clench their teeth on a regular enough basis to lead to dental damage.
While bruxism occurs most commonly in 25 – 44 year-olds, many children also grind their teeth. Britain’s NHS records that one in five children under the age of 11 grind their teeth.
This figure could, however, be higher, as many parents don’t notice that their children are grinding their teeth. And in fact, one of the problems with bruxism is that it is easy to miss, avoid, or misdiagnose.
