I agree with Sasha about the type of adhesive for this application.  However, 
one question I have is the purpose of re-adhering the teeth. If the  
specimens are slated for display, then re-adhering teeth is acceptable, but if  the 
specimens are kept for research, then this may be detrimental to their  value. 
It is virtually impossible for someone re-adhering teeth in a socket from  
which soft tissues are no longer present to re-align the teeth to occlude as  they 
did originally. If the occlusion matters, it is best left to competent  
research to draw their own conclusions, rather than having to deal with someone  
else's opinion, which may or may not be correct. Indeed, sometimes researchers  
are forced to remove the adhesive so that they can examine the possible  
occlusions. 
 
Would it not be best to simply label the teeth so that they remain  
associated with the skull and keep them in the same container with the rest of  the 
specimen?

For the  two situations below, the stable acrylic resin Acryloid B-72
(Paraloid  B-72), an ethyl methacrylate co-polymer, is a good option.
It's available  from www.conservationresources.com and other conservation
material  suppliers.  For application tips, contact a local conservator
who can  examine your collection items in person.  In the case of  the
articulated porpoise, if the fin is too heavy to be adhered securely  at
the one end, yet cannot be pinned, external support may be  required.
The adhesive selected should not be stronger than the object  itself, as
the original material will likely fracture.  For additional  information,

Folks -

I have a related question.  What can I  use to attach disarticulated
teeth from small mammal skulls (coyote and  smaller)?  As an entomologist
and botanist, I have very little  experience preparing skeletons and no
knowledge of the types of adhesives  involved.

Thanks,

We have a small porpoise articulated skeleton that needs  repair.  The 
fins have fallen off and are too delicate to drill and  attach with 
wires (which looks like what has been done several times in  the past).

We've considered using polymethyl methacrolate --PMMA (a  bone cement 
used in orthopedics and dentistry) but it is expensive.   Any 
suggestions for a glue for attaching heavy bones to the rest of  the
skeleton?

Any help is  appreciated,
Irene
