Welcome to Gaia! ::

"Some people have split their tongue by getting a large number of tongue piercings, stretching them, and then cutting between them. The cutting is usually done by tying off using sutues (or dental floss). While this is a slow method, it can be gradual, allowing you time to adjust. However, it can also mean weeks of EXTREME discomfort.

Contact an oral surgeon for references if you want to have it done professionally. Dr. Lawrence Busino in Albany NY has done more than any other doctor in North America, but any oral surgeon that uses a laser should be able to do it with ease, if their ethics allow it. A doctor will normally charge between $500 and $1000 for this procedure. The lasered procedure takes a week or two for primary healing, with full healing in about a month. There are also some private practitioners willing to do this procedure using cautery tools."

That's what I found at BME in their encyclopedia in regards to tongue splitting.

The lizard man went to the said surgeon.
His entry on it can be found here.

Hope that helps. smile

I don't know much aside from those things I've read, but it seems like the laser method would be better for a few reasons.
1. Less pain. (Acording to my reading).
2. A cleaner procedure, so that will reduce a contamination and possible infection risk. (Tying off or cutting sounds less sanitary to me.)
3. Profession oral surgeons do the laser procedure.

Down sides:
1. Sounds like quite a bit of money.
2. It may have to be re-cut to keep from growing back. (So more money there).

That would be my opinion on it since I have not had it done. I don't think I would consider it for myself, but it does look pretty cool.

If you don't seperate the cut it will heal back up. You're supposed to get the inner-sides stitched so that they heal on their own (or so I've been told).
I wondered about the "needing to get it done again and again" thing. But I've read where people didn't like it, and cut it a second time to get the tongue to heal together. If the tongue healed so fast that they had to repeatedly do it over and over to keep it, I don't really know if they would need to get a procedure to reverse it. But then again, this is stuff I've been told, so I can't be completely sure. neutral sweatdrop

I'm serious about trying to get this. Been wanting it for two years and I'll still have to wait for money(if I do get the laser procedure).
I'm just trying to choose how, not if. sweatdrop

Save up money and do it with laser, I as well don't know too much about it, but in general, I'm always for getting anything to do with your body done by the most professional person you can find, even if that means saving for years and flying half way around the globe. Also, saving the money gives you more time for research and thoughts, so it's an other plus side.

Good luck with it, on some people it really looks great!

Tongue splitting intrigues me, but I wouldn't get it done myself. And here's a picture, because I love pictures. I just googled it.
