constant foul taste from my slightly loose crown
one of my dental crowns is slightly loose. As a result, I am experiencing a constant foul taste in my mouth and my breath. I brush and floss regularly and even brush my tongue, yet the foul taste is constant, even immediately following my brushing and flossing routine. My dentist saw no problem with the crown, so he would not do anything about it.
I work with people, so I am very self conscience, 24 hours a day. The taste is beginning to color the taste of everything I eat and drink and I am tired of sucking on mints. What can I do to alleviate the problem?
