The Frontline episode on this topic is worth a watch http://www.pbs.org/wgbh/frontline/film/dollars-and-dentists/ http://www.pbs.org/wgbh/frontline/film/dollars-and-dentists/ My mom went to the dentist for (the beginnings of) a tooth infection and they tried to sell her a mouth guard that probably cost $1000 or so. There was no evidence at all that she was grinding her teeth.
