depending on whether you can prove you have no money, make very little etc. they attend you for free for all dental care in c/. de la cruz 4 in iDental - good service according to my secretary (yes, I pay her little :-), or you pay only partially.
They are just behind the Hospital de Vistahermosa on the avda. Denia - you see them at a distance, a huge red heart with iDental on it ...
