Great set of short videos about specific tooth grinding issues, like causes, treatment, and the difference between grinding and bruxism.

This video did a nice job of explaining tooth grinding and how to prevent and treat it. The dentist was fairly engaging and seemed credible.

interesting Q&A video with a dentist as he explains bruxism, grinding and guards. The video didn't answer a lot of questions, but those asked he seemed to answer in a manner that anyone could understand. This was not the most interesting video I've watched, but it did contain some really good information that will be helpful to many people.
