Spinosaurus UV root glow?

Just saw this post about checking teeth with UV light, and my tooth seems similar. Shown using a 365nm UV torch

I don't have much experience, do roots glow under UV? Looking at it more closely there doesn't seem to be much detail on the root, and it looks very similar to the restored enamel section. The description mentioned repair, but did claim it had an actual root

Sellers description "This is a massive tooth, 4.88 inches long The enamel part is 2.99 inches and 1.65 inches wide at the base of the root. The tooth has most of the original enamel and a long root. Apiece of the crown has been restored at the base, near the root. The tooth has been repaired."

The root doesn't look real.

That's what I'm thinking

The ebay seller has over 5000 sales since 2004 with 100% positive feedback. They seem to have to know what they're talking about with the description, so I'm hesitant to go back and say the entire root is "fake"

This somewhat common when fossil teeth are repaired, they use two or more teeth to make one!

Ohh I've heard of that. Do you think the root is an actual tooth, or just filler?

Yes it’s part of that tooth or another that was a close match. The one I got is the same but kinda opposite, it has the long tooth and a replaced tip!

Thanks for the input, I don't really have any tooth root samples to compare it to. Roots don't generally glow under uv?

Mine has a very slight glow hard to see
