Dentistry/Bitter taste in mouth


txtorn8oh wrote at 2009-04-11 05:42:10
I have also had this bitter taste in my mouth after replacing a metallic/porcelain crown with an all-porcelain crown. I didn't actually notice the bitter taste so much until a corner of the crown chipped off. The bitterness distorts the taste of most everything but especially sweets. I also read that some people had a bitter taste in their mouth after eating pine nuts. I've had these also over the course of several weeks. The bitter taste is definitely stronger after eating pine nuts. Anything sweet tastes bitter on the same side of my tongue as the replaced crown. Coincidence? I've read too many complaints online to think that there is a direct correlation.

I too have recently noticed this sweet, salty and metallic taste in my mouth, on or near the dental work.  The only thing I can attribute this to is the recent dental work I had done...a crown was put on.


I found out the materials that make up a typical porcelain crown: nickel, gold, and other metals in an alloy.  These crowns are placed over an amalgam filling (mercury, silver, tin, copper, zinc).  I am an engineer by trade, and know that differing conductive metals create a current when in a conductive medium (saliva).  These metallic and sometimes sweet tastes are actually your taste senses detecting a galvanic current in your mouth from any dissimilar metals.  This is the EXACT principle behind thermocouples.  If you don't believe me, lick a 9-volt battery and see how it tastes?  These galvanic currents can cause headaches, insomnia, and other health issues for some.

In short, I have attributed this and other health maladies to my dental work.  I am actually perturbed about it, since I just spend $700 on a crown!!  I plan to have my dental work replaced with alternate materials after I save some money.

I have had the same problem for 3 months. I had two teeth filled. One upper and one lower. There is not a tooth next to these teeth, so they are lone standing. I have this horrible bitter taste and tingly tongue almost like acid eating through my tongue. It is truly horrible. This is the first time I've been to this dentist and I am to the point of saying just pull the teeth. They have scheduled me to see a specialist in July..will let you know what he says.

I just had a crown put in and my dentist swears nothing had been done. I have been seeing this dentist for at least 15 years and never had this problem. My only solution now is to have him replace the crown.
