I can recommend a bio dentist in Tijuana. He can give you an estimate of cost based on an X ray. He has many years of experience of Amalgam removal and uses only non toxic materials. Many years of experience with removing dangerous root canals. He uses only non metal and radioactivity FREE materials. Every batch gets tested.
Having been in the location for a longer time a few times, both with myself and also with a different patients, I can arrange an accommodation on beach in a nice house ( internet, bedroom, shower,furnished kitchen) and a private driver at a very friendly cost.
You would be going to dentist every day and in the spare time, you can enjoy beach and be doing trips, enjoy the real mexican food and life !
If interested, please contact me.
