I would definitely get a second or even third opinion. There is a dentist overseas that a lot of Klinghardt patients see - Volz (
http://www.swiss-biohealth.com/). Maybe you could send to him to see what they suggest. From what I've read, it actually ends up being cheaper going to him. Also, maybe there's an option to inject ozone. I'm definitely no expert in this area but I most likely would not be pulling my front two teeth if there's never been any type of work or pain there.
I'm also a bit leary on the implants. They are usually made of titanium which can be a problem for some people. Dick Van**** had some type of mystery illness that ended up being his implants.
