Thanks to all who replied with helpful suggestions on glue for re-attaching teeth.  My question was related to skulls used for educational purposes only, rather than specimens in museum collections that might be analyzed by researchers.  Therefore, issues such as proper occlusion are not a concern.

Thanks again!

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,

Subject: [NHCOLL-L:3377] bone glue?

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
