Human Dental Pulp and Gingival Tissue after Static Magnetic Field Exposure.

Local tissue effects of strong magnets have been evaluated because they are employed to produce orthodontic tooth movements, but many of these studies have failed to distinguish between effects of the static magnetic field (SMF) and cytotoxic effects of corrosion products of the magnetic alloy. The authors therefore evaluated the effects of SMFs produced by resin-encapsulated orthodontic rare earth magnets on human dental pulp and gingival tissues in a clinical study. No histologically detectable changes were seen in dental pulp or adjacent gingival tissues which could be attributed to the magnets. No differences in clinical gingival condition or pocket formation were observed. No signs of sore buccal mucosa were detected and none of the subjects reported any discomfort. The authors concluded, based on the study results and previously reported findings, that there is very little risk of harmful reactions in dental pulp and gingival tissue associated with the clinical use of commercial orthodontic rare earth magnets.

READER COMMENTS
October 23, 2003 - Tress After having a cavity filled yesterday I began having jolts of pain from my tooth. It wasn't constant pain, but would happen every few seconds. I called my dentist and tried the egg yolk also. I guess the sulfur in the yolk is to reduce the "charge". It didn't help and I returned to my dentist in the afternoon. Instead of guaze my dentist placed a green wax strip across the new filling to keep it from connecting to the old filling in my bottom tooth. It has helped. I'll remove it later today to see if the pain has stopped.

August 10, 2003 - Marian I posted here last on Tuesday, August 5, 2003. Update on my galvanic shock episode: I went back to the Dentist that following Thursday afternoon and had the filling removed and had a non-metallic filling put back in. I am now pain free. The gauze that Nichole suggested and the egg yoke did not work.

August 05, 2003 - Marian Today, Aug. 5, 2003 I went to the Dentist to have an old filling removed and a new one put in and part of that tooth had already broken off. (I'm 62 year old female) The Dentist put in a new filling and after I got home I started to have sharp shooting pains in my head. I called the Dentist and they told me to wait about two hours and if I was still having pain to call back, which I did. The Dentist told me that it was like having batteries in my mouth with two separate metals with an electrical charge and as silly as it may sound, he told me to put egg yoke on the tooth. Which I did! (At this point, I would have tried anything). He said this would make the new metal corrosive. I then called my daughter in Virginia, who is a dental assistant and she said it was galvanic shock. I was not told that or that it would last up to 24 hours and go away. I will try the gauze that Nichole suggested and hopefully I will get some relief. This is very painful!

June 27, 2003 - Denise I have been experiencing galvanic shock. I had a filling put in today and when that tooth and the tooth above (which has a silver crown) touch it is very painful. It can be just a small touch and it is very painful. It is almost like putting foil to your tooth except 10 times worse. They say it should go away with in 24 hours. I hope so. Like the other person who left a comment I also put gauze on my tooth and that is the only thing that is keeping me from severe pain.

March 12, 2003 - Nichole I recently experienced galvanic shock after my dentist filled a cavity on the upper right side of my mouth. I described my pain as a feeling of someone having a magnet pulling at my tooth, causing sharp pain throughout that area. In addition, I suffered from a headache on the right side. I went back to the dentist that same day and asked him what could possibly be causing the pain. He told me that it was galvanic shock and that nothing could be done about it. He also said that it would go away in 24 hours. The pain was so unbearable. After the explanation was given, I decided to put gauze over the lower tooth that had previously been filled. Suprisingly enough, it worked. I recommend a method that dentist should practice after filling a cavity - tell the patient to put gauze or some sort of mouth piece over the tooth for at least 24 hours. Even though the pain has seized, is there any adverse effects due to the galvanic shock?

April 5, 1997 - Marny I would appreciate any information on the damage done to dental pulp by a galvanic shock involving amalgam fillings.

September 27, 1996 - Fabrizio Campi, Polytechnic of Milan, Nuc. Eng. Dept. If you know anything else about biological effects of static magnetic fields on tissue I would like to receive more information; particularly, information about dental applications. Thank you.
