I recently had dental work done and, although my dentist claims nothing he
used in my mouth contained gluten, I was terribly ill afterward.  I need to
have a crown, but I don't want to get sick again.  The dentist doesn't really
seem to understand what I need.  Any advice?  Any referrals for Orange
County, CA, dentists who are celiac-friendly?
