Welcome to Justanswer.I will do my best to answer your question.I am not a great typist,be patient and feel free to ask if anything is unclear.A temporary fix for a tooth on a partial would be just that,temporary.The glues that they have available over the counter will dissolve in the mouth and give way.The only other option as a temporary move would be a two part epoxy but the tooth would have to fit exactly in place and all excess would have to be removed.The best bet is this.Most dental offices use a local dental lab.This repair can be done in a couple of hours.It involves using an acrylic powder and liquid to fuse the tooth onto the parial frame and then heat curing it.Some dentists can send you directly to the lab in an emergency and they will repair it there for you.My lab picks up and delivers twice a day so repairs are usually done in a day.If you are not leaving today...I would check with a couple of the offices in your area.Some dentists have the acrylic repair right in their office.One other thing to consider,most dentists worldwide use the same type of acrylic materials and you would probably not be at too much risk of having a repair done in another country if you had to.If there are any other questions pease ask.
