Hi.
I'm going to a Tijuana dental clinic very highly recommended by a fellow waccoista named Anja,
and am thinking of driving rather than flying. They have a range of specialists all under one roof and fees are a fraction of the cost here.
The clinic's number is (619) 819-8671 - they speak English and will gladly let you know fees for procedures.
They have many patients from the US and are used to helping people on their stay and return trip (with medical pass to zip through border).
Driving time is about 10 hours each way. I'll likely stay there at least a couple of days (comfortable hotels can also be shared, if we like; temperatures now in 70's and low 80's) before heading back, with perhaps a fun detour on the way north...
Get in touch soon if you'd like to go.
To your health and bright smile! Jude
