I can't seem to get an answer on weather or not this is normal. The long and short of it is that my temporary crown smells badly. If I wiggle the temp a little and place my tongue on the gumline, I can taste the bad stuff from in there. Is this normal? I've had the temp for about 3 weeks. I rinse with Listerine and brush about 3 or 4 times a day. Can I remove this thing and clean under it? I have the paste stuff to put it back on , but will this be extremely painful?
