Do dental crowns cause bad breath?

my neighbor comes over and when he talks to you close there is a real foul smell in his breath. when I told him about it he said that he had to have his crown removed and replaced with a gold one because the porcelain one gives off a bad odor. any dentists out there agree?

Do dental crowns cause bad breath?
Im not a dentist but I can say from experiance


porcelain crown with or without gold crown


do not give or retain odrs





People with crowns think they dont have to brush thier teeth


because crowns dont rot like teeth do





however brushing is about TEETH GUMS and Tongue





a foul odor means that person has extreme tartar build up


and possibly a bad gum disease





tartar build up especially the thick lower front teeth type from coffee and cigarettes plain ol' STINKS
Reply:i thought having gold in your mouth makes ur breath pretty RANK. sounds like he needs to learn how to floss and brush his teeth/tongue properly.
Reply:I've had a porcelain crown for over a year and my breath never stinks!
