EXcellent dentist probably the same office mentioned above.  The guy is called Josep I think but don't know the name of the woman.  Both have more than adequate English.  Bit pricey but that's probably the norm here.
Fmom the Corona Hotel roundabout, walking towards the old bridge.  Turn left at Lidl and the office is a few doors up on the left.  Ring the bell if nobody on reception.  Receptionist doesn't have good English but you'll get sorted.
