Last week we discussed the use of night guards for nighttime grinding or clenching. Many patients deny clenching at night but still have a lot of muscle pain around the jaw joint and ear area. These people probably actually clench their teeth during the day.
A study of daytime clenchers was designed so that patients were reminded to check where their teeth were every 20 minutes.
Even this almost constant reminder did not lessen the patient’s clenching and there was no difference between men and women
However, the level of perceived stress was higher with patients that clenched during the day and these people clenched or just touched their teeth together during the day 4 times more often than the control subjects.
