Clenching can be silent
Grinding involves tooth surfaces moving against each other. Clenching applies pressure, even without an audible sound. Both can be forms of bruxism.
It can happen during the day too
Bruxism does not occur only during sleep. Unconscious clenching can also happen during the day, for example when feeling tense or concentrating.
The effects vary from person to person
Strong or frequent activity can strain the teeth and chewing muscles. Symptoms and possible damage are assessed alongside habits.
