This is an interesting set of old dental plaster moulds consisting of a profile of lower teeth and gum and an undividual tooth.  
 
The front tooth on lower teeth profil has been marked with green ink - we're assuming this is where work may have been needed on the patient.
 
Sold as a pair.
 
Great for display purposes.
