A Grinding Question

I was attending a presention by the vendor providing administration services for my employer's health insurance policies ("benefits", in American business vernacular).

When the dental policy was explained, a colleague asked if it covers the cost of dental guards used to reduce the damages of teeth grinding.

"It does not", answered the presenter, "but this isn't a common need as far as I know," emphasizing, they asked: "How many people here grind their teeth so hard they need such a device?"

Most of the software engineers in attandance raised their hands.
