www.bbc.com/future/story/20160301-the-gruesome-and-mysterious-case-of-exploding-teethBetween 1817 and 1920 there are a number of reported cases of people suffering from serious toothache finding relief when their teeth exploded in their mouth. The explanations for what was going on both rest with the fillings used during this time. The first explanation is that decay in the tooth caused gases to build up, eventually causing the tooth to burst. The second is that the metals used in fillings created a small battery, causing a build up of hydrogen in the tooth that was set off by a spark also caused by the metal. I think it would be interesting for MB to take a look at this myth, and see if they could figure out what was going on.

Wow, I heard that one a long time ago and had quite forgotten all about it until you mention it?.
However, I have heard it was because of the type of substances that were used in the fillings, "That have since been banned", which may or may not match what you say there...
What I remember was a case of a filling becoming painful and "Explosive decompression" I suppose, but just popping out, some have said like a popcorn kernel going off, in the mouth, not always causing damage, just one hell of a surprise...
Well, I suppose, if that did happen and you just went "Oh, better call a dentist then", you either have nerves of steel or are legally high at that time?..

Do you have any links to the story about fillings popping at altitude? That would be a good addition to the main story.

I would suppose, as always, we would have to deal with the question of what they define as an explosion. an abscess building pressure and popping a filling out could be considered an explosion.

No links to a story but my friend was flying out to meet me years ago and the crowns on her front teeth popped off at altitude. She was not happy when she landed. It was her first flight ever and I had to talk her into it. She said when the plane got up to altitude her caps just "popped" off into her mouth. I always assumed the was a gap inside and the air inside expanded. If you scroll down on this page to Dental Barotrauma (about a 1/4 way down the page) it describes similar occurrences noted back in WW2 www.nature.com/bdj/journal/v206/n1/full/sj.bdj.2008.1121.html?foxtrotcallback=true |
