Well I got a cleaning and whitening aside from a language barrier sometimes. The process is easy and straight forward. Although you are not sure with some if they are giving you a higher price. The thing about health care compared to all other goods there is no way to Universally compare price/ quality /predict the future for after care if needed. All the dental facilities I have visited here are very clean and appear professional. I understand alot of Spanish but it gets a bit scary if you say yes to the wrong thing and a translation app has it faults. So having a doctor that can atleast explain your diagnosis in English is a major plus I would imagine for most travelers.
