Tooth had broken off the night before, including veneer. Contacted this clinic and had v. quick response next morning. Molds made same day (a Tuesday) at clinic and plastic (temporary) crown put in. Proper crown done on Friday morning. I chose a zirconium crown rather than porcelain - it's more expensive, but lasts forever and never stains. ( I researched it myself )
The dentist I saw did some training in California, so was easy to communicate with. His assistant, though eastern European, is fluent in Spanish and pretty good in English too. Nice office and neighbourhood (very near Arguelles Metro, and a huge park as well). I walked it both times from Calleo.
