Andreas has given me plenty of free advice. I took what made sense to me, and left what didn't.
Conversely I had a mercury filling out last year. All in all it cost me around $1000. For 1 filling! (plus all the extras like initial appointment, xrays etc.).
The actual filling cost about $400 which worked out to about half an hours work!!
That makes an hourly rate of about $800.
$130 is nothing in comparison.
You are barking up the wrong tree. The real crooks are the ones with the degrees and acreditation, who don't give a stuff about you but just want your cash. Bu$$ine$$.
