My partner has a loose crown...any suggestions for professional assistance here in Nice? Thanks!
I would ask at your hotel to see if they can recommend a local dentist.
Don't know about Niece, but my husband had a crown put back on in 2011 in Florence. We got the dentists name from the people we were renting from (we had an apartment at the time). The crown is still on and it was a gigantic 20euros for the visit Our dentist was astounded at the price we paid. Said he could not have done it for less than 200 dollars.
Good luck.
Inquire at the nearest pharmacy.
Here's the US State department's list of doctors/dentists in the Nice area: http://photos.state.gov/libraries/france/45994/pdf/nice-doctors.pdf In addition your travel insurance company can provide you with recommendations as well.
