at first i wouldnt worry

The crown is nickle, the glue that was holding it is the most toxic and the yuky tase he smelled/tasted when it came off was the deadliest nest of bacteria known to mankind that was producing trillions of babies to be swallowed in his saliva.

THE CROWN will not get stuck, it will pass out like normal food. Most people when eating nuts will swallow chunks as large as crowns and most people swallow food chunks much larger than crowns.

"IF" he wanted to save it and you knew you swallowed it, you walk outside and stick your finger to your throat and PUKE! I had to do this when my mouth was loaded with crowns.

Otherwise, now he has to check each bowel movement............I suggest all crowns are bad news and time to remove the root and have a blank spot to remind him for the rest of his life of his health condition. Naturally people won't go to this extreme and seek to replace their crown.

2 tsp. of real seasalt in a quart of water will flush the entire digestive tract.
then you'd put a sieve in the toilet...

crazy to add to your worry "deadly bacteria"...while you're in this predicament--oregano oil, olive leaf, all that stuff can be taken after--but yes, unless you (he) wanted to vomit, the salt water flush or the epsom salts is the way to move it out fast.

the SWF works best in the morning..

I swallowed my crown, too! I had no idea what to do and was clueless as to how long it would take to pass. But I couldn't afford a new one, so the day after I swallowed it, I went about the disgusting task of squishing through my excrement every day until I found it. I am a thin young woman and I tend to have a small bowel movement every morning. I had swallowed my tooth on a Sunday morning. Every day thereafter, I went about squishing through my stuff after my morning poop every day. After a while week passed, I was beginning to lose hope. I was sure that I must have missed it. Especially after reading on countless medical sites that anything you swallow will leave your body within 48 hours. Well, on the eighth day, HALLELUJAH!! It came out! This was on the NEXT Monday!! So, a full right days after I swallowed my tooth, it finally emerged. I've noticed that several other people who've posted stories of tooth retrieval took around a week as well. So don't give up hope! I am a skinny girl with a fast metabolism who craps every day, yet out still took me eight days to expel my tooth. I'm glad now that I endured this instead of paying five hundred for a new one. It was truly disgusting, but once you get a routine down, it gets easier. And, if like me, you poop once a day, then you stl only have to go through the process around seven times (if, also like me, you take around a well). So hang in there and remember that a LOT of others have had to go through this, too. Whatever doesn't kill you makes you stronger, haha.

And, if like me, you poop once every single day, then you still only have to go through the process around seven times (if, also like me, you take around a week, as well).
