Is this T-Rex Tooth restored?

[jikohr]

Hi everyone!

I recently acquired a very large (3.5+ inches) digested Rex from McCone County, Montana. The seller said no repair or restoration and I just wanted to make sure. I shined a UV light on it and there is one area that I'm interested in. Along the mesial Carinae is a very dull green under the UV. I tried to capture it with my phone but all I got was blue light since my Camera isn't equipped for that. Typically when I see restoration it's a very bright and vibrant green under UV so I'm not sure if this dull green area is restoration, if it's just an area that was stabilized, or if that's just there sometimes.

Here are the pics I took, although my question is primarily "what does very dull green under UV light mean?"

Any insight is appreciated!

To my eyes, its not jumping out as having restoration.  If it was, it paint blended to the rest really well, and that much should REALLY stand out under a UV light.  I think you may just be seeing some artifact from heavy consolidation.

Boy it sure looks restored.  You can see a color and texture change bit past half-way down the tooth and no carina.

Really? I looked at that area with the UV light and didn't see anything. Will restoration not show under a UV light? Could the tooth being digested change the texture? here's some more pics.

Your new photos re a bit better.

Could just be a very poorly preserved tooth where the enamel and some of the dentin is worn.  UV should show paint. You can try acetone to see if that effects anything.

poorly preserved is how it was advertised to me so I'm fine with that. You can just never be to careful with these things you know.

I'm not to experienced using acetone how do I use it in this case? Just want to make sure I do it right and don't mess it up (more than it already is).

If the tooth is natural pretty hard to mess it up. Just wipe the sides with a wet cotton swab and see if anything changes.  If its coated with a substance it will remove it

Well I applied acetone and some stuff came off so confirmed funny business. Contacted the seller, got a large partial refund so I'm happy.

I think this speaks for itself. Quite a few things one could make an analogy to.
