A crack in tooth - how much restoration?

[AranHao]

Hello,there

I Spinosaurus tooth that has no repair or restor as mentioned in the introduction, with a crack. After receiving it, I found that the crack was continuous and it seemed entirely possible that it was broken. Later, I used acetone to wipe the cracks, and the cracks showed white dentin. After thorough wiping, the teeth did not break (acetone removed the glue). 

I want to know if this tooth has repaired crack? 

How can a complete crack appear without breaking?

Thank you for any viewpoints.

Looks to me as if this tooth was broken in half and then glued back together.

Glued 

 

also the area where tooth crown meet the root also look suspicious .

Thank you for your point of view. I fully used acetone to wipe the entire tooth. If glue is used, why doesn't it disintegrate

[BirdsAreDinosaurs]

I agree that it looks glued and that the area where crown and root meet looks suspicious.

 

Just wiping the tooth superficially does not remove the glue in the center of the tooth.

Not that I would recommend doing so, but if you soaked the tooth in acetone for long enough. I expect it would split into two halves.

Could also be that the glue used is not reactive with acetone.

I am trying to completely soak it in acetone overnight to see if it will disintegrate.

Why?

 

Many fossils get broken during extraction from matrix and glued back together. The two halves of your tooth seem to line up fairly well so I think they are part of the same tooth and not a composite. 
 

Personally, I would leave it as is. I see no reason to soak it in acetone overnight and potentially destroy the fossil. I just see the soak doing more harm than good.

The seller is highly honest and purchased this tooth because it has no repair. In the description, it is only a crack and there is no crack repair. If it will disintegrate, I will request a refund.

[AranHao]

Is it 100% certain that it is crack repair? I will request refund.

I would also advice against soaking it. I would say that at least it is quite clear that some restoration/painting has been done to hide the crack and some minor damage.

 

If the tooth falls apart from soaking it, it might be hard to return it.

 

Personally, I do not mind a crack repair if the two bits align up nicely.

 

Chances are that the seller is honest and did not recognize the crack for what it is.

This is also a good possibility. In my experience, quite often glue on teeth from Morocco does not dissolve  in acetone.

Sincerely thanks for everyone's opinion!

Yikes!... do not soak it in acetone. I echo others.... why?  There may also be microcracks that were glued  before they fell apart that you cannot see.  If you soak it long enough to dissolve the main break (I repeat... why?), then any other cracks held together with the same glue will also fall apart and may not be easily repaired.
