Dentist in Budapest: any recommendations?

Hi

I am privileged to travel to Budapest early September. I would like to consult a dentist there, too. Can anybody recommend a good practice? Staff should be English or German (or French : Protected content , as I do not speak a word of Hungarian. Also it would be good to be able to consult on Saturdays, although this is not mandatory (I'll arrive on Thu. 2.9 and leave the following Sun.)

Thank you very much for your advice!

Kind regards from Geneva
