Hello! Like many of you, I'm seriously considering traveling to Costa Rica to have extensive dental work done, as cost are prohibitive in the US. I know I have a lot more research to do, as there are so MANY postings on this topic, but I'm curious if anyone has had any experience with Dentavac. I have read one or two reviews and several postings by the same person...has anyone else had any experience with them? Or any other recommendations?
