My lower right molar has broken and so did the amalgam filling.  I am now experiencing upset stomach and diarrhea.  There is very minimal pain in the tooth, no swelling or redness.  I dont feel very well overall.  I need to also mention I have Lupus.
Hello Dairy have gone through your query. I will try to give my best possible advice to you. Commonly it is very unlikely that an amalgam filling causes diarrhea since there can be several more common causes like contaminated food or water for diarrhea to occur. Gastric upset and bloating may be caused if the mercury is ingested(accidentally or through leaching of extra mercury from the filling), but it is very rare. Lupus also doesn't seem to have any relation with your diarrhea. But still I will advise you to check with your dentist again and discuss the problem. But firstly visit your physician to get diarrhea treated.Meanwhile, I am advising few things - Take Rest - Take electrolytes(ORS), - Stay HY Chat Doctor.
