Is it ok for someone with shoulder bruxism or rotator cuff problem to use cold compress for comfort and to help with healing?

While a cold compress may not fix the underlying problem, it can provide symptomatic relief and is very safe to use.

You should be perectly safe using this technique especially if it reduces the symptoms. However, the use of the term Bruxism, coined in 1931 by Bertrand Frohman, MD which comes from the Greek expression “brychien odontas, really refers to the grinding of the teeth and the complication resulting from this habit.
